型钢高强混凝土剪力墙性能设计方法研究
|
摘要
通过6个剪跨比分别为2.1、1.5和1.0的型钢高强混凝土(SHRC)剪力墙低周反复水平加载试验,研究不同剪跨比下SHRC剪力墙的破坏形态。根据本试验SHRC剪力墙在不同阶段的破坏程度并结合其他相关试验数据,统计给出了SHRC剪力墙在使用良好、暂时使用、生命安全和防止倒塌四个性能水平对应的位移角取值建议。在试验研究基础上,建立SHRC剪力墙极限位移角计算公式,计算结果与试验结果符合较好,提出SHRC剪力墙基于性能的变形能力设计方法,最终给出SHRC剪力墙不同轴压比限值下,满足特定目标位移需求的约束钢筋数量,可供工程设计时参考使用。
Cyclic loading tests of six steel high strength concrete(SHRC) shear walls with shear span ratios of 2.1,1.5 and 1.0 were conducted and the failure patterns of the shear walls under different aspect ratios was studied.On the basis of the damage levels of SHRC shear walls,the limit state of the different seismic performance levels and their dominating parameters are proposed.The performance of SHRC shear walls can be divided into four levels,performance continuity,performance interruption,life safety and collapse prevention.The story drift ratio of SHRC shear walls are developed for four different seismic performance levels and the ultimate drift ratio are calculated using numerical method.Comparison between calculation results and test results illustrates that those calculating procedure is feasible.A performance-based deformation capacity design method was developed for SHRC shear walls and the transverse reinforcement characteristic value in accordance with the target top displacement ratio and axial load ratio was proposed.
