底部两层框架—抗震墙砖房抗震分析的计算机方法

Computer Method of Earthquake Analysis for Masonry Buildings with R.C.Frame and Shear Wall in the Bottom Two Stories

通过对比计算分析 ,结合同类型结构 1 3比例模型试验及课题研究 ,提出了相应的计算机分析方法 ,并编制出电算程序。引入墙板单元分析抗震墙 ,对于地震倾覆力矩的分配及底部框架梁承担竖向荷载合理取值等采用新的研究成果。本方法可以作为相应课题研究的配套技术 ,在这类房屋的抗震设计中应用。

Based on A 1/3 scale model test of typical structure , an analytical method by computer is presented through comparative calculation and analysis. A computer program is also worked out. The plate?wall element is adopted for the analysis of seismic structural wall. Some present research results on the distribution of earthquake overturning moment and the rational value of vertical load beared by the bottom frame beam are adopted. The method can be taken as the technology of a complete set for the relative research project and applied to the seismic design of such type of building.
