复杂高层建筑结构动力弹塑性分析方法及其应用

Elastic-plastic time-history analysis method and application of the complex tall building

复杂高层建筑结构的竖向刚度和承载力变化大、受力复杂,易形成薄弱部位,宜采用弹塑性分析方法进行补充计算。基于现有弹塑性分析方法的基础上,重点介绍了动力弹塑性分析的目的、原理及方法,指出了动力弹塑性分析时应注意的问题。最后给出了动力弹塑性分析方法在具体工程中的应用。

Great variation of vertical stiffness and bearing capacity of the complex tall buildings,which have characteristics of complexity of stress and are easy to form weak site. Elastic-plastic analysis method should be adopted to calculate the complex tall buildings. Based on existing elastic-plastic analysis method,the paper was emphasis on the objective, principle,method of elastic-plastic analysis and pointed out the problems for attention on elastic-plastic analysis method. Finally,elastic-plastic analysis method in the engineering application was provided.
