型钢混凝土剪力墙变形性能指标体系试验研究
Experimental Study on Deformation Performance Index System of Steel Reinforced Concrete Shear Walls
摘要
Abstract
In order to revise the deformation performance index system of steel reinforced concrete(SRC)shear walls of Guangdong provincial standard Specification for Performance-based Seismic Design of Reinforced Concrete Building Structure(DBJ/T 15-151-2019),12 steel reinforced concrete(SRC)shear walls were designed and tested under low-cyclic loading based on current standard.Seismic behaviors,such as failure pattern,energy dissipation capacity,deformation capacity and displacement ductility were investigated.According to the test results,two performance state division methods based on skeleton curve and failure phenomena were proposed respectively and a comparison between the two methods was made.The deformation performance index limits obtained by these two methods were consistent and could be characterized each other,which verified the rationality of the performance state division method based on skeleton curves.Based on this,the relationship among deformation,extent of damage and bearing capacity of the component was established.Based on the low-cyclic loading test results of 104 specimens,including 12 specimens in this paper and 92 specimens collected from literature,failure mode classification was revised and the regression formulas for the key performance points(θ1,θ5,θ6)of SRC shear wall were established.Finally,the established regression formulas for the key performance points were adjusted by exceedance probability based on ASCE/SEI 41-13,and the deformation performance index limits of SRC shear walls were revised.关键词
