摘要

摘要: 为研究半刚性框架内填波纹钢板剪力墙对结构抗震性能影响,利用ABAQUS建立数值模型进行探索分析。通过设计3种不同构造的波纹钢板剪力墙,并与半刚性框架相结合,研究此结构体系抗震性能。首先建立单层单跨有限元模型,与现有文献中相关研究模型进行对比验证,确保模型精确性。然后在此基础上建立3种不同构造的波纹钢板剪力墙体,分别与此半刚性框架相结合形成半刚性框架-波纹钢板剪力墙结构体系,研究体系在侧向力作用下抗震性能,最后探究半刚性框架内嵌不同墙体的结构体系剪力分配规律。有限元研究结果表明:半刚性框架(KKJ)具有较好的延性,但其抗侧刚度较小,承载能力不高,能量耗散较稳定但耗能不强;半刚性框架内填墙体(KKJ-Q1)能大幅增加体系刚度、承载力及耗能能力,使其延性降低;墙体填充泡沫混凝土(KKJ-Q2)可抑制波纹钢板屈曲,提高墙体整体性能,其刚度、承载力、耗能能力进一步增加;墙体两端设置加强端(KKJ-Q3)能避免墙体过早发生破坏而失去承载力,刚度、承载力都有一定程度的提升,随着加强端高度增加,导致墙体塑性变形从两端向中心转移,墙体破坏模式从弯曲变为弯剪,刚度、承载力及耗能能力进一步提升;随着外荷载增加,墙体剪力呈现先上升后下降趋势,墙体剪力占比Q3＞Q2＞Q1,墙体刚度与剪力占比呈现正比关系。

Abstract: In order to study the influence of corrugated steel plate shear wall in the semi-rigid frame on the seismic performance of the structure, a numerical model was established by ABAQUS to explore and analyze. Three different corrugated steel shear walls were designed and combined with the semi-rigid frame. First, a single-layer single-span finite element model was established and verified with the relevant research models in the existing literature to ensure the accuracy of the model. Then, on this basis, three corrugated steel plate shear walls with different structures were established, which were combined with the semi-rigid frame to form a semi-rigid frame-corrugated steel plate shear wall structure system. The seismic performance of the system under the action of lateral forces was studied, and finally the shear distribution law of the structural system of different walls embedded in the semi-rigid frame was explored. Finite element results showed that the semi-rigid frame (KKJ) had good ductility, less antilateral stiffness and low bearing capacity, its energy dissipation was relatively stable but the energy consumption was not strong; the semi-rigid frame filling wall (KKJ-Q1) could greatly increase the system stiffness, bearing capacity and energy consumption capacity, so as to reduce its ductility; the wall-filled foam concrete (KKJ-Q2) could inhibit the buckling of corrugated steel plates and improve the overall performance of the wall, its stiffness, bearing capacity and energy consumption capacity were further increased; the strengthening ends at both ends of the wall could avoid premature damage of the wall and loss of bearing capacity, its stiffness and bearing capacity had been improved to a certain extent, as the strengthening end height increased, to the plastic deformation of the wall shifted from both ends to the center, the wall failure mode was changed from bending to curved shear, the stiffness, bearing capacity and energy consumption capacity of the wall were further improved; as the external load increased, the wall shear force showed the trend of rising first and then decreasing, the shear ratio of wall Q3> Q2> Q1, the wall stiffness and shear ratio were proportional.
