| 摘 要： | 采用有限元方法,同时考虑几何和材料非线性效应,对某单榀张弦桁架结构在强震下的弹塑性动力变形性能进行分析.结果表明:该结构桁架部分的局部杆件进入塑性发展较快且程度较深,最后因塑性大量发展导致结构位移过大而失去使用功能;在竖向地震加速度峰值为10 m/s<'2>以内时,结构没有出现动力失稳现象;在峰值加速度为8～10 m/...

| Abstract: | By finite element method,considering the geometric and material nonlinear effects,dynamic distortion capability of one single truss string structure was studied under severe earthquake.The results showed the phenomena occurred faster with great degree development that local structure members entered into the plastic operating condition,which resulted in the use of functional of the whole structure loss because of large displacement;there was not the phenomenon of dynamic instability within vertical accelera... |
