摘要
提出了一种适用于村镇建筑的装配式轻钢框架—轻墙板组合结构,基于该组合结构在低周往复荷载作用下的抗震试验及理论分析,利用有限元软件Abaques对1榀组合结构标准试件进行建模,并采用位移控制的单向分步加载进行了力学性能模拟,验证了模型的正确性和有限元分析方法的合理性。结果表明,装配式轻钢框架—轻墙板组合结构有良好的力学性能,在地震作用下具有明显的两道抗震防线,结构安全可靠。
A kind of fabricated lightweight steel frame-lightweight panel composite structure suitable for village and town buildings was proposed.Based on the seismic test and theoretical analysis of the composite structure under low cyclic reciprocating loads,the finite element software Abaques is used to model one normal composite structure specimen. The mechanical performance of the model is simulated by the unidirectional step loading controlled by displacement,which verifies the correctness of the model and the rationality of the finite element analysis method. The results show that the fabricated lightweight steel frame-lightweight panel composite structure has good mechanical properties and has two obvious seismic lines under earthquake. The structure is safe and reliable.
