摘要:
为了使静力弹塑性分析方法应用于高层结构的弹塑性变形计算,该文根据静力弹塑性分析的基本原理并结合高层建筑结构特点,通过理论分析,得到了既考虑多阶振型组合又能反映结构瞬时动力特性的静力弹塑性分析改进方法。算例计算表明:文中提出的改进的静力弹塑性分析方法可以适用于高层建筑结构在地震作用下的弹塑性变形计算;并且由于高层结构抗侧移刚度较小,在地震作用下侧向位移曲线受高阶振型影响明显。
Abstract:
A method of static elasto-plastic analysis is applied to calculate the elasto-plastic deformation of high buildings under the seismic action.From the basic principle of static elasto-plastic analysis combined with characteristics of the structure in high buildings,an improved method of static elasto-plastic analysis including both the combination of multi-mode vectors and the instantaneous dynamic characteristics of the structure is presented.The calculation results show that the improved method of static elasto-plastic analysis is applicable to calculate the elasto-plastic deformation of high buildings under the action of earthquakes.Because the lateral stiffness in high buildings is smaller,the lateral displacement shape on elasto-plastic deformation under the seismic action is obviously influenced by the higher mode vectors of the structure.
