Abstract ：

Precast segmental bridge columns are commonly used but merely in low-seismicity areas, since their seismic performance is not clear under actual earthquake motions. To evaluate the feasibility of precast segmental columns in high-seismicity areas, it is necessary to investigate the dynamic behavior of such columns under bidirectional seismic excitation owing to multi-dimension characteristics of earthquake ground motions. Two 1/ 10-scaled columns with continuous low-carbonated rebars between segments were designed and reinforced with ultra-high-performance concrete (UHPC) based on a proposed design method. Then, shake table tests of reinforced columns were conducted to investigate the influence of types of seismic motions (near-filed and far-field) and loading direction (unidirectional and bidirectional) on dynamic responses of precast columns. The experimental results showed that minor concrete damage occurred in the bottom segment, and 0.2 % residual displacement was found, which indicated the column had an excellent re-centering capacity. Compared with the column under unidirectional seismic excitation, the column subjected to bidirectional seismic excitations had more serious concrete damage, more obvious fundamental frequency reduction, and larger displacement responses at the column top, residual displacement, and peak stress of tendons. The displacement of the column top under bidirectional loads was twice that under unidirectional loads. In addition, the response of the column under near-field earthquake motions was more significant than that of the column under far-field seismic excitations.

Abstract ：

Compared with precast bent caps, high-performance precast bent caps are shorter and lighter, a well-designed precast bent cap can improve the construction rate, and guarantee an acceptable shear resistance capacity. Therefore, an ultra-high-performance concrete (UHPC) with a thin-walled hollow bent cap suitable for short and medium spans was designed, and its mechanical performance was studied. Firstly, a UHPC bent cap model with a scale ratio of 1:3 was cast and used in a 4-point loading test, and its crack propagation pattern, shear resistance capacity, and failure mode of the bent cap were revealed. Then, based on an ABAQUS finite element model verified by the experimental results, the influence of various design parameters on the shear performance of the UHPC bent cap was fully investigated, including longitudinal reinforcement ratio, stirrup ratio, web width, bottom thickness, and the thickness of the top and bottom plates. Finally, a prediction formula of shear bearing capacity suitable for different cross-section types was developed based on the truss-arch model. The results indicated that the bridging effect of steel fibers and diaphragm cloud restrained the generation and extension of cracks during the loading process, thus the UHPC bent cap showed good deformability and shear-resistant capacity. Besides, the shear resistance capacity was improved by the increasing longitudinal reinforcement ratio, stirrup ratio, web width, and the thickness of the top and bottom plates. The accuracy and generalization ability of the established formula was validated by comparing the predicted results with the experimental results derived from this paper and relevant studies. The research can facilitate the application of UHPC and structure lightweight technology in bridge engineering.

Abstract ：

Ultrasonic guided wave (UGW) technique has been widely utilized in damage detection of pre-stressed steel strands. However, most of the current UGW-based methods only focus on bare strands, whereas in real projects the strands are usually pre-buried inside the structure and encapsulated by media such as concrete or grout. In this study, the effects of various grouting and tensioning factors on the propagation of UGW in grouted steel strand, as well as the effectiveness of UGW energy leakage ratio (alpha EL)-based pre-stress evaluation for grouted steel strand, were investigated. Firstly, the theoretical model of UGW propagating in the grouted steel strand was developed. Secondly, a finite element model of grouted strand was established to investigate the dispersion characteristic of UGW as well as the energy distribution and attenuation behavior of UGW in the grout. Thirdly, pre-stressed concrete (PSC) specimens with different grouting diameters, grouting lengths, and tension forces were designed to investigate the effects of grouting thickness, grouting length, and tension force on the group velocity, energy distribution and alpha EL of UGW. Finally, the alpha EL-based approach was validated in pre-stress evaluation for grouted steel strand, and the evaluation accuracy was compared with that for bare steel strand. Results show that compared with the helical wire excitation scenario, the UGW signals propagating in steel strands are significantly less affected by variations in grouting thickness and grouting length under core wire excitation scenario. In the grout, the UGW energy tends to decrease exponentially with the increase of the radial propagation distance, and the helical wire excitation scenario leads to more UGW energy leaking into the grout compared with core wire excitation. It is recommended to excite UGW signal in the core wire instead of the helical wire in alpha EL-based pre-stress evaluation approach for grouted steel strand, in such scenario, the evaluation error is only 4.93 %.

Abstract ：

Ultra-high performance concrete (UHPC) has been widely used in wet joints of precast bridge deck panels (PBDPs) due to its remarkable compressive strength, excellent tensile strength, and exceptional durability properties. However, there is a lack of consistent understanding regarding the mechanical properties of PBDPs with UHPC wet joints, especially shear behavior. To investigate the shear performance of PBDPs with UHPC wet joints, a total of seven bridge deck panels (BDPs) were designed and conducted by four-point bending tests. The test parameters included reinforcement types (straight bar and U-bar), lap details (contact lap and non-contact lap), joint widths (150 mm, 200 mm, 250 mm, and 500 mm), and filling materials (NC and UHPC). According to the test results, the shear behavior of seven BDPs was analyzed. The experiment results showed that all specimens exhibited shear failure, with critical shear cracks occurring in the shear span. For PBDPs with U-bars, the shear capacity of 200-mm-wide UHPC wet joints was 1.5 % higher than that of 500-mm-wide NC wet joints. In addition, the failure pattern had a tendency to gradually shift from shear failure to flexural failure when the width of UHPC wet joints was reduced from 250 mm to 150 mm. To establish 3D finite element (FE) models, a cohesion-friction hybrid model was proposed. The FE models had good simulation accuracy, with a maximum deviation of 7.0 %. Furthermore, a parametric analysis was performed to assess the influence of critical parameters on shear performance. The results showed that longitudinal reinforcement has a greater influence on the shear performance of PBDPs. Finally, shear capacity formulas in the design codes were verified in comparison with test results. The deviation of theoretically calculated values from test results was within 10 %.

Abstract ：

Over the past decade or so, ultra-high performance concrete (UHPC) has been increasingly used for wet joints of bridge deck panels (BDPs) in bridge superstructures. To evaluate the flexural performance of UHPC wet joints for precast bridge deck panels, a total of seven BDPs were designed, including one monolithic cast-in-place bridge deck panel (MCIPBDP), one precast bridge deck panel (PBDP) with NC wet joints, and five precast bridge deck panels (PBDPs) with UHPC wet joints. The design parameters included reinforcement types (straight bars and Ubars), U-bar lap details (contact lap splice and non-contact lap splice), filling materials (UHPC and NC), and joint widths (150 mm, 200 mm, 250 mm, and 500 mm). Three-point bending tests were performed to evaluate the flexural performance based on the failure mode, load-deflection curve, cracking width in the wet joint region, and stiffness degradation. The experimental results showed that it is feasible to replace 500-mm-width NC wet joints with 200-mm-width UHPC wet joints for PBDPs with U-bars. UHPC wet joints, with a width of 250 mm, effectively prevented straight bars from slipping. As the width of UHPC wet joints decreased, the failure mode shifted from shear failure to bending failure. In addition, the cohesion-friction hybrid model was proposed to simulate the behavior of joint interfaces. The FE analysis results demonstrated that the FE model and modeling method have high accuracy and general applicability. Finally, the flexural capacity calculation formula was developed according to the strut-and-tie model. The theoretical calculation results were in good agreement with test results.

Abstract ：

This paper investigates the cyclic behavior of a steel self-centering (SC) rocking column. The steel SC rocking column consists of an H-section steel column and a pair of shape memory alloy (SMA) slip-friction dampers (SMASFDs). As the kernel part, the SMASFDs enhance SC capability of the rocking column and dissipate the input energy. The working principle of the rocking column is first described, along with the analytical equations that govern the behavior under loading cycles, which are validated by experimental data. The component tests were conducted on the NiTi SMA bar and the slip-friction mechanism, separately. And then, the cyclic loading tests were conducted on a 1:2-scaled rocking column specimen. The considered axial force ratio included 0, 0.1 and 0.2. During the entire experimental procedure, the SMA bars were neither repaired nor replaced. It is found that up to a drift ratio of 7 %, the rocking column maintained stable flag-shaped hysteresis, which is characterized by excellent SC capability and satisfactory damping capacity. The testing results also indicated that increasing axial force ratio effectively increased the strength and stiffness of the rocking column, whereas it reduced the post -decompression stiffness due to the P-Delta effect. Finally, the numerical models were established in ABAQUS and OpenSees, both of which were verified by the experimental data, and a parametric study was carried out.

Abstract ：

精确的有限元分析(FEA)依赖于材料的准确定义。通过编写用户子程序UMAT实现了大断裂应变纤维增强聚合物(LRS FRP)在纤维方向上拉伸特性的定义。基于Abaqus中混凝土塑性损伤模型的理论框架，提出了一种改进的混凝土塑性损伤模型用于定义LRS FRP约束混凝土的材料特性。这些改进包括：通过LRS FRP约束混凝土的实验数据校准了与屈服准则相关的参数K；硬化/软化准则与约束刚度相关；流动法则与轴向塑性应变相关。采用修改后的材料模型进行FEA，结果表明：FEA预测的应力-应变曲线与实验结果吻合。基于FEA的结果，讨论了矩形柱截面上应力分布的不均匀性，根据约束效果可分为有效约束区域和弱约束区域，且在约束有效区域上应力分布不均匀性随着截面比(长边/短边)的增加而增加。

Abstract ：

为评估地震作用下大应变纤维增强聚合物(large rupture strain fiber reinforced polymer, LRS FRP)加固桥梁的抗震性能，以一典型三跨连续梁桥为例进行了研究。目前关于LRS FRP约束混凝土往复轴压模型的研究较少，限制了LRS FRP加固桥梁的抗震分析。因此介绍了作者课题组提出的简化LRS FRP约束混凝土往复轴压模型，根据此模型并结合地震易损性分析理论，基于OpenSees平台，采用增量动力分析(incremental dynamic analysis, IDA)方法，对三跨连续梁桥在LRS FRP加固前后的地震易损性进行了分析。结果表明：轻微损伤和中等损伤状态下桥梁墩柱基本处于未受损坏的线弹性阶段，LRS FRP加固对其地震易损性影响不大；严重破坏和完全倒塌状态下，未加固桥梁的损坏超越概率明显大于LRS FRP加固的桥梁。提出的简化LRS FRP约束混凝土往复轴压模型可为LRS FRP加固桥梁的抗震分析提供参考。

Abstract ：

Buckling of the longitudinal rebar is one of the main forms of plastic hinge failure in reinforced concrete (RC) columns after an earthquake. This rebar buckling significantly impacts the seismic bearing capacity and energy dissipation capacity. To restrain the development of longitudinal rebar buckling behavior and delay the degradation of lateral strength in RC columns, this paper developed a new type of buckling restraint rebar (BRR) consisting of three components: longitudinal rebar, a restraint sleeve, and foam material. First, the BRR mechanical properties under compression and tension-compression cyclic loading were obtained through quasi-static loading tests. Then, the BRR compression and tension-compression cyclic loading processes were numerically simulated based on ABAQUS finite element software. The simulated results were compared with the test results. Finally, a stress-strain constitutive model for this new BRR was proposed based on this study. Results showed that the restraint sleeve could significantly enhance the lateral stiffness and the bearing capacity of longitudinal reinforcement after yielding. The compressive performance of BRR was mainly affected by the length and wall thickness of the sleeve. The cyclic performance was mainly affected by the length of the sleeve and the clearance between the sleeve and the reinforcement. The BRR constitutive model proposed in this paper can accurately reflect the influence of restraint sleeves on the stiffness of longitudinal reinforcement after yielding.

Abstract ：

Prestressed structures are widely employed in bridges and large-span spatial structures, and the accurate evaluation of prestress state is of great importance for structural maintenance. This paper reviews the nondestructive testing (NDT) and health monitoring techniques for structural effective prestress. Specifically, the fiber Bragg grating (FBG) sensor-based, magnetic-elastic (ME) sensor-based, dynamic response-based, ultrasonic guided wave (UGW)-based, electromechanical impedance (EMI)-based, and electrical resistance-based methods are reviewed in this paper. Firstly, the principle, application range, and measuring accuracy of each technique are introduced and analyzed, and the benefits and limitations of each technique are summarized: The FBG sensor and ME sensor take on high measuring accuracy and have been applied in practical engineering, but they are required to be preinstalled during structural construction; the dynamic response-based method is greatly effective in cable force assessment but not suitable for prestress evaluation of prestressed concrete (PSC) structures; the UGW-based, EMI-based, and electrical resistance-based methods have shown favorable potential for prestress assessment in laboratory experiments, but their feasibility and accuracy in practical engineering need to be verified. Secondly, the challenges and discussion of each method are discussed in the following four aspects: measuring range, reliability of measuring results, stability and durability considering long-term monitoring, and cost-efficiency. Finally, a decision tree is proposed to choose the most appropriate prestress evaluation method in a specific application scenario.
