LYP160低屈服点波纹双钢板混凝土组合剪力墙抗震性能分析
Seismic performance analysis of LYP160 low-yield point corrugated double-steel concrete composite shear wall
摘要
Abstract
In order to better improve the seismic performance of the double-steel concrete composite shear wall,a new LYP160 low-yield point corrugated double-steel plate was proposed to replace the flat steel plate in the composite shear wall structure,and 12 groups of specimens were designed with concrete strength(C30,C40,C50 and C60)and medium and low shear span ratios(2.0,1.5 and 1.0)as the main parameters,including 6 groups of ordinary steel specimens and 6 groups of low-yield steel specimens.The finite element software was used to establish a new LYP160 low-yield point corrugated double-steel plate composite shear wall structure model,and by drawing hysteretic curves and skeleton curves,the seismic performance of 12 groups of specimens,including their bearing capacity and ductility,stiffness degradation and energy dissipation capacity was analyzed.The results show that:1)With the increase of concrete strength,the bearing capacity of ordinary steel specimens and steel specimens with low-yield point increases,the ductility decreases to a certain extent,and the energy dissipation capacity basically does not change.Under the same concrete strength,the ductility of steel with low-yield point is better than that of ordinary steel.2)With the decrease of the shear-span ratio,the bearing capacity of ordinary steel specimens and low-yield point steel specimens increases,and the ductility decreases slightly.Under the same shear-span ratio,the ductility of steel with low-yield point is increased by 70.83%compared with that of ordinary steel.The study proves that the bearing capacity,ductility,stiffness degradation and energy dissipation capacity of LYP160 low-yield point steel corrugated double-steel plate concrete composite shear wall are significantly improved compared with ordinary specimens,and have good seismic performance,which can provide theoretical reference for the application of LYP160 low-yield point steel corrugated double-steel plate concrete composite shear wall.关键词
