SAP2000纤维铰模型在某核工程静力弹塑性分析中的应用

Static Pushover analysis and application of a nuclear project by fiber hinge in SAP2000

本工程紧邻主厂房,而主厂房是与核安全有关的Ⅰ类物项,需对其在极限安全地震动下的变形性能进行验算。通过静力弹塑性分析方法,采用SAP2000的纤维铰模型对结构的弹塑性进行模拟,从而得到结构在极限安全地震动下各构件截面不同位置处材料的应力应变发展情况。本文采用的方法可供同类工程设计时参考和使用。

This project is near by the main power house which is Ⅰ type item relate to nuclear safety,therefore checking computation of the mechanical performance under the ultimate safety ground motion is necessary. This paper carries out static pushover analysis by the fiber hinge in SAP2000 to simulate the elastic-plastic response,resulting in the stress and strain of the materials in the different place of each component under the ultimate safety ground motion. This method can be a reference for the engineering designers to design this kind of structures.
