摘要
采用截面纤维模型对南水北调中线工程中的某典型渡槽的支撑框架结构进行了罕遇地震作用下的弹塑性动力时程分析,分析结果表明,该渡槽在罕遇地震作用下,没有明显的薄弱部位,最大层间位移角在限值以内,具有良好的抗震性能。
This paper made elastic-plastic dynamic time history analysis on a typical aqueduct support frames structure using section fiber model to south-to-north water transfer middle route project. The analysis results showed that, under rare earthquake this aqueduct had no obvious weak parts, the maximum displacement angle within the specified value, had a good seismic performance.
