摘要：为研究型钢再生混凝土框架-再生混凝土砌块填充墙框架的抗震性能，通过有限元软件ABAQUS建立了型钢再生混凝土框架-再生混凝土砌块填充墙结构的有限元模型，并进行了分析，通过与已有试验结果进行对比，验证有限元建模方法和本构关系的正确性，在此基础上对框架进行了破坏模式分析，并进一步分析了填充墙对框架抗震性能的影响。研究表明，填充墙的应力分布主要是沿斜对角的受拉应力，在填充墙的角部区域应力较大，中部区域砌块发生滑移错动。在试件的加载过程中，加载初期，填充墙对框架的承载力影响较大，在加载后期，由于填充墙发生破坏，填充墙对框架承载力的贡献减弱，但填充墙的存在一定程度上约束了框架的整体变形，延缓了框架柱柱脚的塑性变形。

Seismic performance analysis of steel reinforced recycled concrete frame infilled with recycled concrete blocks
Abstract: To study the seismic performance of steel reinforced recycled concrete frame infilled with recycled concrete blocks, the finite element model of steel reinforced recycled concrete frame infilled with recycled concrete blocks were established and analyzed by finite element software ABAQUS, and the correctness of the finite element modeling method and intrinsic structure relationship was verified by comparing with the existing test results, and on this basis, the failure mode analysis of the frame was carried out, and the study of the influence of the infill wall on the seismic performance of the frame was further analyzed. The study shows that the stress distribution in the infill wall is mainly tensile stress along the diagonal, with higher stress in the corner region of the infill wall and slip misalignment of the blocks in the central region. In the loading process of the specimen, the infill wall has a greater influence on the frame bearing capacity at the initial stage of loading, and at the later stage of loading, the contribution of the infill wall to the frame bearing capacity is weakened due to the damage of the infill wall, but the existence of the infill wall restrains the overall deformation of the frame to a certain extent and delays the plastic deformation of the frame column footings.
Keywords: steel reinforced recycled concrete; recycled concrete block; frame-infill wall; seismic performance; finite element analysis
