多途径综合开发商业软件精细求解土石坝结构静动力反应
摘要
以ADINA软件为例,提出联合开发和调用外部控制程序、自带本构模型二次开发接口、相关计算模块及前后处理模块的思路,全程自动实现各模块的调用计算和数据间的相互传递,一次性完成土石坝静动力反应的精细求解,综合开发时仅对软件自带二次开发接口不能实现的功能进行外部程序编写。通过与著名动力计算程序SHAKE91经典算例的对比分析以及一高土石坝三维静动力反应的工程应用,表明所建议的方法功能拓展性强,数据传递高效快捷,且计算结果合理可靠。这一方法也可推广用于ABAQUS和ANSYS等商业有限元软件,以弥补这些软件在精细求解某些特定问题时自身的不足。
Taking ADINA for example,based on external program and native constitutive model secondary development program,it is put forward that the static analysis module,frequency analysis module and seismic analysis module can be united called and data is transferred among these modules to realize the automatic finely calculation for static and seismic analysis of earth rockfill dam.External program is developed only towards the function which can.t be realized with ADINA's user-supplied program.A classical calculation example in famous seismic analysis software SHAKE91 is analyzed with the suggested method.The results of comparative analysis and seismic safety study of a high earth rockfill dam show that the method suggested is high efficient,easily programmed and reasonable.This method can be similarly applied to the development of ANSYS,ABAQUS and other finite element softwares to make up for their lack of solving certain programs.
