一、引言 SAF5程序是以有限元法为基础编制的线性结构静动力分析程序。其通用性强、适应面广,有相当大的解题规模和较高的解算效率。多年以来应用于解决机械、航空、土木等许多部门的实际课题,证明其分析结果是可靠的。目前仍是敌国装机最多、应用最广、受到广泛欢迎的结构分析通用程序。但是,对于从事工程结构分析或建筑设计的技术人员来说,SAP5输出的内力只不过是中间结果,还有必要作进一步加工处理,如荷载组合、内力包洛、计算配筋等.现在提出的SAP5配筋程序(以下简称配筋程序)正是在分析SAP5结构功能的基础上, I. INTRODUCTION The SAF5 program is a static and dynamic analysis program for linear structures based on the finite element method. Its versatility, wide adaptation, there is a considerable problem-solving scale and high efficiency of the solution. It has been used for many years to solve practical problems in many sectors such as machinery, aviation, civil engineering, etc., and has proved that the analysis results are reliable. At present, it is still the general procedure of structural analysis with the most installed, most widely used and widely welcomed by the enemy countries. However, for technical personnel engaged in engineering structural analysis or architectural design, the internal force output by SAP5 is only an intermediate result, and further processing is necessary, such as load combination, internal force, calculation of reinforcement, etc. Now proposed The SAP5 reinforcement program (hereinafter referred to as the reinforcement program) is based on the analysis of the structural functions of SAP5.
