摘要：为研究再生砌体填充墙-型钢再生混凝土框架结构的抗震性能，试验设计了1榀再生混凝土框架和2榀再生砌体填充墙-型钢再生混凝土框架并进行低周往复加载试验。试验结果表明：纯框架试件及带填充墙框架试件均为延性破坏，填充墙沿框架平面对角线区域破坏较为严重，梁端与柱端先后出现塑性铰，符合“强柱弱梁”的抗震设计概念；带填充墙框架相比纯框架峰值承载力提升80%左右，平均位移延性系数大于6,表明其具有良好的变形能力；带填充墙框架在加载前期耗能能力强于纯框架试件，后期因填充墙破坏而承载能力迅速下降，极限位移较小，耗能能力弱于纯框架试件；轴压比越大，带填充墙框架峰值荷载后的延性和耗能能力下降越快。基于现有等效斜压杆理论对试件进行Pushover分析，结果表明Klingner模型与试验结果吻合最好。合理布置的填充墙可作为结构抗震的第一道防线，性能点处结构满足“大震不倒”的抗震要求。

Seismic performance analysis of recycled masonry infill wall-shaped steel recycled concrete frame structure
Abstract: In order to study the seismic performance of recycled masonry infill wall-shaped steel recycled concrete frame structure, one specimen of recycled concrete frame and two specimens of recycled masonry infill wall-shaped steel recycled concrete frame structure were designed and subjected to low cycle reciprocating loading test. The test results show that both the pure frame specimens and the frame specimens with filled walls have ductile failure, and the failure of the filled wall is more serious along the diagonal area of the frame plane, and the plastic hinge appears successively at the beam and column ends, which accords with the seismic design concept of “strong column and weak beam”. The peak bearing capacity of the frame with filled wall is about 80% higher than that of the pure frame, and the average displacement ductility coefficient is greater than 6, indicating that it has good deformation capacity. In the early stage of loading, the energy dissipation capacity of the frame with filled wall is stronger than that of the pure frame specimen, but in the later stage, the bearing capacity decreases rapidly due to the failure of the filled wall, and the ultimate displacement is smaller, and the energy dissipation capacity is weaker than that of the pure frame specimen. The larger the axial compression ratio is, the faster the ductility and energy dissipation capacity of the frame with filled wall decreases after peak load. Pushover analysis of specimens based on the existing equivalent baroclinic bar theory shows that Klingner model is in good agreement with the test results. Reasonably arranged infill walls can serve as the first line of defense against earthquakes, and the structure at the performance point can meet the seismic requirements of “no collapsing under the rarely-occurred earthquake”.
