摘要
运用编制的有限元程序(SATWE),以底部剪力法为基础,采用整体分析和分开分析两种方法对框架上门式刚架结构进行计算,绘出框架上门式刚架的内力图和变形图。在两种分析方法下,讨论此结构不同的内力与变形产生的原因,并比较两种分析方法的合理性,以期对此种结构抗震设计的研究提供依据,得出合理的结构设计。
In this paper,based on the bottom of shear method,the finite-element method(SATWE) is used to analyze the influence of holistic approach and partial approach on force analysis of steel moment frame with portal frame to arrive at the force diagram.This paper not only discuss the difference of the force and the deformation but also contrast rationality of the two methods.Through this study,the author hoped to get the study of seismic analytical method and design the structure.
