基于11个高强混凝土钢板剪力墙模型试验,采用有限元软件PERFORM-3D完成了不同设计参数的试件在低周反复荷载作用下的模拟分析,对比了抗剪承载力、刚度、滞回性能等参数,验证有限元模型的合理性,确定整体结构中剪力墙模型参数.采用非线性时程分析,对比研究带高性能剪力墙的超高层框架-核心筒结构与带普通钢筋混凝土剪力墙的超高层框架-核心筒结构整体地震响应和剪力墙材料损伤等差异.分析结果表明:带高强混凝土钢板剪力墙的超高层框架-核心筒结构底部剪力墙的损伤程度和范围明显减小,其底部剪力墙混凝土最大压应变与原结构相比最大可减小42.9％,钢板最大拉应变与原结构相比最大可减小64.9％.构件试验与整体结构分析均证明高强混凝土钢板剪力墙结构抗震性能优越,结构底部剪力墙损伤得到有效控制.
Study on seismic performances of super high-rise frame-corewall structure with high strength concrete composite steel plate shear walls
Based on 11 model tests of C80 high-strength concrete (HSC) composite steel plate shear walls, finite element software PERFORM-3 D was used to simulate seismic performances of the specimens with different parameters under low cyclic loading, and shear capacity, stiffness and hysteretic behavior were compared to verify the rationality of the finite element model and determine parameters of shear walls used in simulation of the overall structure. Then nonlinear seismic time-history analysis was used to study the differences of seismic responses and damages of shear wall material between super high-rise frame-corewall structure with high strength concrete composite steel plate shear walls and super high-rise frame-corewall structure with ordinary reinforced concrete shear walls. Results show that the damage degree and range of bottom shear walls of C80 HSC steel plate shear wall of super high-rise frame-corewall structure with high strength concrete composite steel plate shear walls are significantly reduced. The maximum compressive strain of bottom shear wall concrete can be reduced by 45.2％ compared with the original structure. The maximum tensile strain of the steel plate can be reduced by 65％ compared with the original structure. Component test and seismic analysis of the whole structure have proved that high strength concrete composite steel plate shear wall structure has advanced seismic performances, and damage of bottom shear wall can be effectively controlled.
