摘　　要：推导了空间网格结构几何非线性地震响应计算过程、编制了结构动力特性、地震响应反应谱法与时程法的核心计算程序。以AutoCAD为平台、采用Visual C++6.0编制了各计算分析模块的人机对话控制界面,并开发结构分析所必须的前后处理模块,操作表明,分析模块人机对话控制界面的研制使得计算中各控制参数的输入极为简单;前后处理模块的开发使得结构建模与结果查看直观方便。The calculating formulas of geometrical nonlinear seismic response of spatial grid structure are deduced. The core calculating programs of structural natural vibration characters, ~ponse spectrum and time-hlstory methods on structural seismic response are developed. The dialog interfaces between user and computer of each calculating module are developed using Visual C ＋ ＋ 6.0 based on AutoCAD graphics environment ; the pre-processing and post-processing programs are also developed. The operation of examples shows that the dialog interfaces of calculating module make the input of controlling parameters during calculation very easy ; and the pre-processing and post-processing programs make modeling of structures and examining of results very convenient.
