Abstract ：
To achieve thermal load-bearing integration in reinforced concrete shear wall, this study innovatively proposes a prefabricated ceramsite foam concrete sandwich shear wall (CFCW), in which ceramsite foam concrete (CFC) is employed as an interlayer between normal concrete (NC) layers, effectively combining thermal insulation with structural strength. In this study, four full-scale CFCW specimens with different boundary elements were tested through quasi-static tests under varying axial compressive ratios.The results indicated that all the specimens exhibit primarily flexural failure modes, and an increase in axial compressive ratios enhanced the bearing capacity, initial stiffness, and energy dissipation capability of CFCW specimens while simultaneously reducing their deformation capacity. Furthermore, finite element models were established using OpenSees to simulate the seismic behavior of CFCW, and the results validated the effectiveness of the model. Building upon this, a parametric analysis of the finite element model was conducted, which provides significant reference for the engineering application of CFCW structures.

Abstract ：
A cantilever block wall-panel attachment strip (CBW) flexible connection node was designed to connect precast concrete (PC) exterior wall panels to steel frames. To investigate the performance of the CBW flexible connection node and PC exterior wall panels during earthquakes, a partial two-storey steel frame was extracted from an actual engineering structure, and a full-scale steel frame-exterior wall panel shaking-table model was designed. Two sets of shaking-table tests were conducted under seismic intensity 7, 8, and 9 (Chinese Seismic Intensity Scale) earthquakes. The acceleration and displacement responses of the composite wall panel, open window panel, and integral wall panel along the in-plane and out-of-plane motions were analysed. The acceleration amplification factors of the PC exterior wall panels ranged from 0.753 to 1.400 (in-plane) and from 0.998 to 2.199 (out-of-plane). The CBW flexible connection node had a deformation capacity that could coordinate the deformation of the exterior wall panel and prevent severe damage. The surfaces of the PC exterior wall panels remained intact during a very strong seismic intensity 9 earthquake.

Abstract ：
In this study, the axial compressive performance of steel-concrete-steel composite walls (SCSCWs) with novel dumbbell-shaped connectors (DSCs) was investigated. Six specimens were designed and tested, and the study parameters included the physical dimensions and arrangement schemes of DSCs. The failure mode, axial displacement, steel strain, and bearing capacity of the specimens were analyzed. The external steel plates exhibited local buckling, and the internal concrete was crushed. The variation in the physical dimensions of the DSC had little effect on the failure modes, and increasing the number of connectors improved the bearing capacity of the specimens. The axial load-displacement relationships of the SCSCWs were calculated considering the effects of local buckling and post-buckling behavior of steel faceplates in the constitutive relationship. The theoretical curves were in good agreement with the experimental results. A simplified formula for the bearing capacity was proposed, and the average ratio of the experimental to theoretical peak loads was 0.98, indicating that the simplified formula had high accuracy. ABAQUS software was used to simulate the axial behavior of SCSCWs. The simulated results were similar to those of the experiments, and the average ratio of the experimental bearing capacity to the corresponding simulated value was 0.99. Based on the benchmark model, further parameter analyses were conducted to study the effects of material strength and physical dimensions on the axial behavior of SCSCWs. Increasing the material strength and sectional thickness could increase the bearing capacity, and the failure mode was not affected. The theoretical initial stiffness of the SCSCWs was calculated, and the accuracy of the formulas was verified using the simulated results.

Abstract ：
In this study, quasi-static tests were conducted on six steel-concrete-steel composite wall (SCSCW) specimens with novel dumbbell-shaped connectors (DSCs) to investigate their seismic performance. The research parameters included the connector arrangement scheme and the axial load. The failure mode, load-displacement curve, and strain data were analyzed in detail. All the specimens exhibited flexural failure, and the experimental phenomena included the local buckling of external steel plates and compressive failure of internal concrete. The local buckling located between the foundation and first row of connectors, had a limited effect on the bearing capacity of the specimens. The connectors effectively controlled the buckling range of the external steel plates. With increasing axial load, the deformation capacity of the specimens decreased significantly. Under the same displacement, the greater the axial load, the greater the secant stiffness, and the higher the accumulated energy dissipation value. When the load reached its peak value, the yield range of the bottom front steel plates of specimen with large axial load was less than that of the specimen with small axial load. The theoretical formula accurately calculated the flexural bearing capacity of SCSCWs, and the maximum error and the average ratio which was defined as experimental value to calculated value were 9% and 1.02, respectively. The horizontal load-displacement relationship of the specimens was calculated using the OpenSees software, and the maximum error of the bearing capacity was 4%. The parametric analysis showed that increasing the steel plate thickness can effectively improve the bearing capacity of SCSCWs.

Abstract ：
This paper studies the shear behavior of U-shaped steel-concrete composite beams (USCCBs), which include eight full-scale beam specimens with different loading directions, loading positions, and shear span ratios. The USCCB is composed of reinforcing bars, encased concrete, U-shaped steel plate, headed studs, and novel dumbbell-shaped connectors. The three-point loading tests were carried out to confirm the shear failure mode and force-transfer mechanism of a concentrated load. The diagonal compression failure of encased concrete, welding fracture and local buckling of U-shaped steel plate, and cracking and spalling of concrete slab were observed in the experiments. The displacement ductility factor of eight specimens was between 1.55 and 3.61, and a rapid drop of the load did not occur in this study. The concrete slab reached ultimate compressive strength, the U-shaped steel plate mainly reached yield strength, and the steel-concrete relative slip or separation did not occur before the load reached peak value. The loading direction and shear span ratio have more effect on the bearing capacity of specimens. The novel connector controls the buckling range of the steel plate, but it has less effect on the bearing capacity. The transfer path of the shear load was measured and analyzed by strain data, and the included angle was between 33.5 degrees and 49.2 degrees. The calculation method of shear capacity for USCCB specimens was proposed, and the average ratio of calculation/test was 1.04.
