摘要
应用ABAQUS有限元软件,对钢框架双钢板组合剪力墙试件进行模拟计算。通过改变结构中内填混凝土板厚度、钢板厚度、混凝土强度及剪跨比等参数来分析结构的骨架曲线、滞回曲线和刚度退化曲线。计算结果表明:试件极限承载力受钢板厚度以及剪跨比的影响较大,受混凝土强度等级和混凝土板厚度影响较小;试件钢板厚度越大、剪跨比越小、混凝土板厚度增大、混凝土强度等级提高,试件的滞回曲线饱满,耗能能力较强,抗震性能较好。
Steel frame bi-steel-plate composite shear walls specimens were simulated using the finite element soft-ware ABAQUS. The effects of the infilled concrete wall thickness, steel-plates thickness, concrete strength and shear span ratio on the specimen properties were analyzed based on the skeleton curve, hysteresis curve and stiffness degradation curve. The analysis results show that the ultimate load is more affected by steel-plate thickness and shear span ratio but less affected by concrete strength and concrete-plate thickness; with the increasing of steel-plates thickness, concrete strength and concrete wall thickness and the decreasing of shear span ratio, the hysteretic curve is full, energy dissipation capacity is strong and the seismic capacity is great.
