精确多分段杆单元模型及其应用
|
摘要
利用结构力学原理推导得出了考虑剪切变形影响的精确多分段杆单元模型的单元刚度矩阵．采用简化桩模型与精确多分段杆单元模型来模拟独立桩承框架结构,输入El-Centro地震波,对一幢七层独立桩承钢筋混凝土框架结构进行地震反应时程分析．并把采用精确多分段杆单元模型的分析结果与采用多分段杆单元模型和5分段杆单元模型的分析结果进行对比,来验证精确多分段杆单元的精度及采用精确多分段杆单元的必要性．图11,参13．
A considered shear deformation affect,exactitude multi-segment bar member's stiffness matrix was deduced by structural mechanics principle.And then,exactitude multi-segment bar member and simplified pile model were adopted to simulate a seven-story R/C frame supported by some isolated piles.Inputting El-Centro earthquake acceleration records,its seismic responses were computed by time history analysis method.Precision and necessary of the exactitude multi-segment bar member were demonstrated by comparisons of seismic response of three different type element models.11figs.,13refs.
