摘要
利用有限元分析程序SAP2000,以两个框架结构为例对结构进行pushover分析和时程分析,研究结构在地震作用下的反应。对pushover方法应用于不同高度的结构和几种不同的加载方式做了详细的研究,研究内容包括由pushover分析得到的结构破坏时的层间位移分布以及结构变形曲线、结构构件塑性铰的分布情况等,并使其结果与时程分析相比较,分析了pushover方法的不同加载方式的特点和适用范围。
By making use of the finite element analysis program SAP2000,the paper,with the two frames as examples, makes pushover and time history analyses of the structure and studies its reaction to earthquake. The paper studies in great detail the applieation of the pushover method to structures of different heights and several load patterns. The content of study includes the distribution of layer displacement when the structure is destroyed,the deformation curve of the structure and the distribution of the plastic hinges of the structure＇s components. The paper also compares the result with the time history analysis and analyzes the characteristics and application scope of the pushover method＇s different load patterns.
