摘要
利用有限元软件ABAQUS对纯钢框架试件、冷弯薄壁型钢组合墙体试件、钢框架-冷弯薄壁型钢组合墙体试件、覆双面OSB板的钢框架-冷弯薄壁型钢组合墙体试件进行水平低周往复荷载作用下研究,分析了试件的滞回曲线、骨架曲线、抗侧刚度、延性和耗能等。结果表明,钢框架与冷弯薄壁型钢组合墙体有明显的组合效应;冷弯薄壁型钢组合墙体能明显增强钢框架结构的承载力、刚度、延性和耗能能力;覆双面OSB板钢框架-冷弯薄壁型钢组合墙体结构抗震性能较不覆板的钢框架-冷弯薄壁型钢组合墙体结构抗震性能好。
The finite element software ABAQUS was used to study pure steel frame specimens,cold-formed thin-walled steel composite wall specimens,steel frame-cold-formed thin-walled steel composite wall specimens,steel frame-cold-formed thin-walled steel composite wall specimens covered with double-sided OSB plates under horizontal low cyclic loading.The hysteretic curve,skeleton curve,lateral stiffness,ductility and energy dissipation of the specimen were analyzed.Results show that steel frame and cold-formed thin-walled steel composite wall have obvious combination effect,cold-formed thin-walled steel composite wall can obviously enhance the bearing capacity,stiffness,ductility and energy dissipation capacity of steel frame structure,and the seismic performance of steel frame-cold-formed thin-walled steel composite wall structure with double-sided OSB plates is better than that of steel frame-cold-formed thin-walled steel composite wall structure without plate.
