摘要
本文讨论了大型通用线性结构静动力有限元分析微机程序PCSAP5的主要特点以及开发过程中的几个问题与所采取的技术策略。作者采用自行研究成功的特殊的综合复盖技术突破了连接关,成功地将原来只能在大中型机上运行的SAP5改造成为可在现行的各种微机上整体运行的微机程序。PCSAP5保留了原SAP5的全部功能;它在普通微机上最大可以求解14000～16000自由度的问题;它具有增强了的绘图功能,实现了与AUTOCAD的自动连接,可支持在任意绘图硬设备上输出图形。
Some problems and technical considerations about developing the general-purpose structural analysis program PCSAP5 executable on personal computers are discussed. The most difficult problem of linking was solved by using a special overlay technique developed by author. PCSAP5 can be run on all PC series of personal computers, while its ability has been extended to such a high level that it is able to solve a large problem with up to 14000-16000 degrees of freedom. It has an enhanced plotting function which can output drawings on any plotting hardwares. It has the same accuracy as that of SAP5 on large computers.
