摘要
针对单层框一桥结构体系,运用结构塑性极限分析原理给出了在罕遍地震作用下可能出现的破坏机构及相应的极限荷载半解析解.通过比较分析,得出最可能出现的几种破坏机构,从而可求出最小的破坏地震作用.
The different collapse mechanical modes corresponding to vertical load and horizontal severe earthquakes are obtained for the single story braced-frame structures, the semi-analytic solution is derived by the way of plastic analysis for ultimate loads of the structures. The most possible collapse mechanism is found by comparison, and then the minimum collapse earthquake action is given.
