摘要:

对SAP2000n程序中静力弹塑性分析的基本原理及实现步骤进行分析,并结合中国规范对其中一些参数加以调整.最后用程序对一个四层框架进行静力弹塑性分析和抗震性能评价.结果表明:该方法可从层间位移角、塑性铰分布及变形等方面对结构进行综合的量化评价,并能揭示出结构在罕遇地震作用下的薄弱环节,是实现基于性能设计的有效方法.

Abstract:

The basic principle and implementation steps of static elastoplastic analysis in SAP2000n program are analyzed, and some of these parameters are adjusted in combination with Chinese standards. Finally, the static elastoplastic analysis and seismic performance evaluation of a four-layer frame were carried out by program. The results show that this method can comprehensively and quantitatively evaluate the structure from the aspects of interlayer displacement angle, plastic hinge distribution and deformation, and can reveal the weak links of the structure under the action of rare earthquakes, which is an effective method to realize performance-based design.
