Abstract ：
Reinforced concrete (RC) shear walls, as one of the most critical load-resisting components, are widely used in tall building structures. They are probably subjected not only to seismic loads but also to out-of-plane impact loads from vehicles, rockfalls, missiles, and other sources. While numerous studies have focused on the seismic performance of RC shear walls, research on their impact behavior, particularly their residual axial compression performance after impacting, remains limited. Based on this, this study investigates the dynamic response of RC shear walls under impact loads and their residual axial compressive capacity after impacting based on numerical analysis. First, a numerical model of RC shear walls under impact loads was developed using LS-DYNA software, and the validity of the numerical model was verified through comparison with experimental data. Then, this study further explored the effect of various parameters on the peak impact force, out-of-plane deflection, deformation modes and residual axial compressive capacity of the RC shear wall, including impact velocity, impact height, shear-to-span ratio, and shape of impactor. Numerical results indicated that the peak impact force and deflection increased linearly with impact velocity. Impact height (varying from 0.25H to 0.75H) and shearto-span ratio (varying from 1.0 to 2.0) had little effect on impact force but increased peak deflection by 295 % and 32 %, respectively. The shape of impactor significantly influenced the impact force, with larger contact area resulting in higher force. However, peak deflection remained similar for different impactors, 42.56 mm for the sphere, 38.17 mm for the cylinder, and 38.44 mm for the cuboid. The residual axial compressive capacity of postimpact RC shear walls was primarily influenced by the impact velocity and shape of impactor. Finally, empirical formulas were proposed to estimate the residual axial compressive capacity of RC shear walls. The findings of this study can provide a valuable reference for the impact collapse analysis of RC shear wall structures.

Abstract ：
Reliable intensity measures (IMs) are essential for machine learning (ML)-based structural seismic damage assessment because they capture critical ground motion characteristics relevant to structural damage. The inherent randomness of ground motions and the structural diversity of urban buildings require a subset of IMs instead of a single IM for large-scale seismic damage assessments to enhance the predictive accuracy of ML models. A comparative study of filter and wrapper methods was conducted to identify optimal subsets of IMs tailored for reinforced concrete (RC) frame structures in urban building clusters. The process involved: 1) constructing a structural damage database for typical urban RC frames through seismic response analyses on established simplified numerical models; 2) establishing a comprehensive set of IMs, comprising 34 IMs proposed by the authors and 49 collected from literature; 3) evaluating individual IMs using filter methods based on criteria such as correlation, efficiency, practicality, and proficiency, selecting top-ranked IMs, and organizing them into distinct subsets; 4) using wrapper methods, such as forward selection, backward elimination, and genetic algorithm, to initially select subsets of IMs, which were iteratively refined based on the performance of ML models to achieve optimal accuracy; 5) comparing the performance of the subsets derived from filter and wrapper methods, identifying those with acceptable accuracy and the smallest number of IMs; 6) validating the bestperforming subsets through seismic damage assessments of three campus buildings. The framework was demonstrated using extreme gradient boosting (XGBoost) and random forest as representative ML algorithms. The performance of filter and wrapper methods was evaluated across various types and scales of IM sets. Applicable scenarios for each method were analyzed considering predictive accuracy and efficiency, and critical subsets of IMs were recommended for ML-based seismic damage prediction of urban RC frame structures. The results provide reliable and efficient decision support for post-earthquake damage assessment of urban buildings, as well as valuable references for fragility analysis of individual structures.

Abstract ：
Precast concrete (PC) frame structures using wet connections consist of composite beam and column including prefabricated and cast-in-situ concrete parts, characterized by specific complex load mechanisms when large structural deformation is induced during progressive collapse. Therefore, PC beam-column substructures using specific construction methods of wet connections were focused: 1) in PCWC-1, connected beam reinforcements through mechanical sleeves and anchored reinforcements using anchor plates; 2) in PCWC-2, anchored beam reinforcements by bending the end into 90 degrees; 3) in PCWC-1, connected column reinforcements by grouting sleeves with thread connections in one end, while in PCWC-2 by similar sleeves with overlapping reinforcements in one end. Collapse tests were conducted under quasi-static uniformly distributed load (UDL) to get actual responses close to engineering practice. And the corresponding collapse resistance mechanisms were examined analytically. The experimental results indicated that: 1) in the compressive arch action (CAA) stage, higher concrete strength of the cast-in-situ parts was vital for improving the collapse resistance performance of the PC substructures, with the peak load reaching 134 kN, 23 % greater than the 109 kN in the reinforced concrete (RC) substructure; 2) in the catenary action (CA) stage, anchor plates reduced the substructure's ductility, but the 90 degrees bending enabled the PC substructure to achieve a collapse resistance of 168 kN, comparable to the RC's 158 kN. The analytical results demonstrated that: 1) in the CAA stage, beam flexural action primarily contributed to the collapse resistance, with higher-strength cast-in-situ concrete increasing the contribution in the PC substructures by 29 % compared to the RC substructure; 2) adopting cast-in-situ concrete at each beam-end segment resulted in more balanced bending moment developments at the beam-end sections near the middle and side columns, compared to using concrete toppings alone, with moment ratios of 3.5/10 and 1.5/10, respectively, at the peak load stage; 3) in the CA stage, the bending moments developed along the beam due to UDL that induced curved beam deformation, together with the axial force of the reinforcement jointly contributed to the collapse resistance. However, the bending moment contributed less in the PC substructures (9 % similar to 13 %) than in the RC one (18 %), due to weakened cooperation of the prefabricated and cast-in-situ beam parts.

Abstract ：
Under a strong earthquake, the axial force of shear walls in tall buildings may vary from compression to tension, but few studies have been conducted on this. Three low-aspect-ratio reinforced concrete (RC) wall specimens subjected to coupled variable axial tension-compression and lateral load were tested in this study, to investigate the effect of the fluctuating range of axial force and loading histories on the shear behavior of RC walls. The test results indicated that shear-compression failure occurred under the compressive-shear loading for all test wall specimens, and no obvious post-peak strength degradation in tension-shear loading. The hysteretic curves of test wall specimens were strongly affected by the loading histories; the shear strength and deformation capacity were mainly affected by the fluctuation of axial forces, especially for tension-shear strength. The equation of ACI 318-19 and JGJ 3-2010 conservatively predicted the shear strength of RC walls under the variable axial force, while the equation of ASCE/SEI 43-05 accurately predicted the shear strength with the mean values of the VTest/VASCE of 0.97 and 0.94 for compression-shear and tension-shear strength, respectively. Comparison with an RC wall under constant axial tension revealed that the failure modes of RC walls were strongly dependent on the initial cracking patterns. Finally, a finite element (FE) model was developed, and parametric analyses were carried out to further estimate the effect of variable axial force on the cyclic shear behavior of RC walls.

Abstract ：
Post-tensioned slab systems serve as an effective method to enhance the progressive collapse resistance of concrete flat plate structures by significantly improving the punching shear and post-punching capacities of their slab-column joints. While the existing research mainly focused on the punching shear behaviour of posttensioned slab-column joints in small deformation stages, the post-punching behaviour in large deformations has been overlooked. This study aims to fill this research gap thorough experimental and numerical studies. Experimentally, four slab-column joints, including three post-tensioned specimens (with varied prestressing levels) and one specimen without tendons, were designed and tested. Detailed failure process and load-resisting mechanisms of the specimens at different deformation stages were discussed. The test results confirmed the efficiency of post-tensioning in improving the punching shear performance. Varying prestressing levels have influenced the development of punching shear capacity but did not affect the growth rate of load resistance in the initial post-punching stage. Numerically, validated finite element models were used to predict the post-punching capacities of the specimens. The numerical results indicated that post-tensioning helped increase post-punching capacities, but such an enhancement was independent of the prestressing levels. Additionally, the influence of the rupture strains of both tendons and reinforcement on the post-punching capacity was investigated through a parametric study.

Abstract ：
A series of dynamic progressive collapse tests using the uniformly distributed load (UDL) was conducted, to analyze the robustness of three precast concrete (PC) beam-column assemblies using dry connections of top-andseat angles (TSA-D), strengthened top-and-seat angles (STSA-D), and high-ductility reinforcement (DSTSA-D), under a middle column removal scenario. Finite element (FE) models were also developed to accurately simulate the collapse process. Based on the tests and FE models, comparative studies were conducted on dynamic and static collapse responses of the PC assemblies with identical configuration, loading regime, and boundary conditions. The results showed that: the horizontal reaction force developments were similar under dynamic and static collapse scenarios; under dynamic collapse scenarios, the initial stiffness of the PC assemblies increased due to the strain rate effect, while the peak vertical reaction forces under the compressive arch action (CAA) were smaller than those under static collapse scenarios, attributed to dynamic damage; under both dynamic and static collapse scenarios under UDL, the beam deformed in a downward convex curved shape, with local material deformation becoming more concentrated under dynamic collapse scenarios. An energy-based method for calculating dynamic collapse resistance was evaluated and revised: 1) the traditional method, which converts static responses from static analysis into dynamic responses was found to underestimate the resistance under small deformations due to neglecting the strain rate effect, and to overestimate ultimate resistance by ignoring dynamic damage; 2) by using dynamic vertical reaction forces instead, a more accurate prediction of the dynamic collapse resistance was achieved with a single dynamic collapse analysis. Additionally, dynamic amplification factors for the PC assemblies were calculated based on FE models and static test results providing basic knowledge in whole PC structural level research.

Abstract ：
Majority of progressive collapse incidents of concrete flat plate structures were caused by slab overloading in the form of punching shear failure at a slab-column joint, which exhibit distinctive resistance mechanism from those triggered by column losses. Relevant studies on the slab overloading scenario are scarce. To fill this gap in research and to broaden the perspective on different collapse modes, an experimental test was conducted on a 1/ 3-scale 2 x 2-bay flat plate substructure specimen by applying an increased downward uniform load on the slab, until the structure was completely damaged following the initial punching shear failure at the interior slabcolumn joint and was unable to take any further load. In addition, the flexural capacity of the specimen was evaluated using the yield line theory, and an analytical model was also proposed to estimate the post-punching peak load of the specimen. Finally, the experimental results obtained from this study were compared to those of a similar test under an interior column removal scenario. Comparisons indicate that the specimen under the slab overloading scenario displays better collapse resistance than that under the column removal scenario. Nevertheless, the residual resistant capacity of the overloaded specimen may not be adequate enough to prevent the collapse of the entire structure after the initial punching failure.

Abstract ：
This paper aims at assessing the impact of removing various numbers of perimeter columns on the integrity of RC flat plate substructures. Compared to interior columns, those at the corner and edge positions on the building perimeter are more likely to damage by accidental and abnormal loads, which in turn may cause progressive collapse of the entire structure. Given the uncertainty of the loading events, the likelihood of multiple perimeter columns being simultaneously destroyed is also high. However, existing research has primarily focused on the single column removal cases. To address this research limitation, a 3D high-fidelity finite element model of a flat plate substructure with a missing corner column (named Model C) was developed. The accuracy of the model was validated based on our previous experiment of the same substructure. The validated model was subsequently modified to cover two and multiple perimeter column removal scenarios. The two new models are namely, Model C_1e in which a corner column and an adjacent edge column were damaged and Model C_2e, with a corner column and two adjacent edge columns being removed. The simulation results reveal that flexural action was the primary load resisting mechanism in all three models. The load carrying capacity with three column removals was reduced by 75.6% compared to the removal of a single corner column. Full-depth cracks were found at the cut-off position of the top slab rebars for the columns adjacent to the removed one(s). In Model C and Model C_2e, cracks exhibited a diagonal axisymmetric failure pattern of the corner of the slab, with equal load transfer to two adjacent columns. In contrast, Model C_1e exhibited a diagonal non-axisymmetric failure pattern of the slab corner, with more loads being transferred to the adjacent column along the shorter bay. The energy-based dynamic response analyses were also performed to obtain the Dynamic Increase Factor (DIF) for the substructure models under different column removal scenarios. Based on the nonlinear regression analysis, the DIFs for the substructures with one and two column removals were found to be ranged between 1.22 and 1.51, and 1.28-1.68, respectively.

Abstract ：
In concrete flat plate slab-column joints with drop panels, successive punching shear failures often occur at the slab-drop panel interface and along the column perimeter. When such joints are subjected to combined bending -shear actions under an eccentric load, their punching and post-punching shear failure behaviours are further complicated which can significantly impact the progressive collapse behaviour of the structural system. An experimental study was conducted on six laterally-restrained slab-column joint specimens with drop panels. Different levels of load eccentricities and different drop panel thicknesses were considered. Two punching shear failure sections were also identified. For a thick drop panel, the first punching failure took place at the slab-drop panel interface, followed by the second punching shear failure occurring along the column perimeter. For a thin drop panel, on the other hand, punching shear failure only occurred at the column perimeter. The damage patterns, the reinforcement strains and the joint strengths before and after punching failure at two different sections were analysed. Numerical simulation was conducted to investigate the effects of load eccentricity on the inclination of the punching cone. Numerical results showed that the punching cone angles at the slab-drop panel interface and at the column perimeter are, on average, 11.6 degrees and 27.1 degrees, respectively. In addition, larger ec-centricity contributed to higher cross-sectional shear stresses on the eccentric loading side, leading to reduced punching shear strength and earlier damage. Furthermore, the experimental and numerical punching shear strengths were compared against the predictions of the Chinese, American and European design codes. Finally, a post-punching strength prediction method was proposed, and the predicted strengths deviated from the exper-imental results by-16% and 23%, for the thick and thin drop panels, respectively. In addition, the integrity reinforcement was also found to contribute at least 80% to the post-punching shear strength.
