【摘要】 考虑结构本身的不确定性,基于蒙特卡洛随机抽样方法,利用大型通用有限元程序ANSYS,对结构进行弹塑性时程分析,获得结构顶点位移随机分布数据,发现结构本身的不确定性因素对其在地震作用下的反应有较大影响.更多还原

【Abstract】 Considering the uncertainty of structure,based on Monte Carlo Simulation method,a general finite element program ANSYS was used to perform an Elastic-plastic time-history analysis for a power transmission tower.The effect of structure’s uncertainty on its seismic response was observed and researched.更多还原
