首发时间:2008-09-19
摘要:本文概述了目前结构抗震研究中常见的分析方法,介绍了ANSYS/LS-DYNA进行结构动力弹塑性时程分析的原理,在不考虑次梁、填充墙体及电梯间混凝土墙的情况下,通过ANSYS前处理软件,选用BEAM161梁单元,SHELL163弹性壳单元建立框架结构的三维有限元模型,然后利用LS-DYNA软件对这一模型的地震振动过程进行三维非线性有限元模拟,分析了框架结构在人工地震波作用下的位移反应、加速度反应、速度反应和楼板等值应力,再现了结构在地震作用下的动力仿真分析过程,验证了这种仿真方法的有效性。

The Seismic Vibration Process Simulation of Based on ANSYS/LS-DYNA
Abstract:This thesis has summarized the present analysis methods in structure seismic research,introduced ANSYS/LS-DYNA principle in elastic-plastic time history analysis.Without regard to subbeam,infilling walls and concrete walls in elevator room,use ANSYS progressive software,build a 3D finity element model with BEAM 161,SHELL163.Use LS-DYNA software to simulate frame structure’s 3D vibration non-linear finity element process in the earth quake .Analyse displacement reaction,acceleration reaction,velocity reaction,ceiling equivalence reaction,reproduce the process of structure’s dynamic simulation analysis. Validate the validity in the method.
Keywords: time history analysis frame structure, seismic vibration,finite element simulation
