摘要
OpenSees三维有限元软件^([1])是一个可以进行有限元计算、设计参数敏感性分析以及可靠度分析的计算平台,具有开源性以及灵活的构架性等特点。采用OpenSees对混凝土双柱墩进行双向时程分析,并将结果与三维空间有限元软件Midas/Civil进行对比。结果表明:在轴压比分别为3.5%和7%时,程序结算的时程分析结果较为吻合,动力特性分析结果也比较接近。该研究可以为OpenSees建模提供参考。
OpenSees -three dimensional finite element softwareE13 is an integrated computing platform which can carry out finite element analysis, parameter sensitivity analysis and reliability analysis. OpenSees have many features such as open source and flexible architecture. Using OpenSees to have a bidirectional Time -his- tory analysis on concrete double columns pier and the results are compared with the results of Midas/Civil, which is a three - dimensional finite element software. Results show that when the axial compression ratio is 3.5 % and 7%, calculation results of the Time -history analysis and dynamic characteristics analysis agree well by different analysis softwares. This research can provide reference for OpenSees modeling.
