PKPM钢结构节点设计程序的重建与改进

Reconstruction and Improvement of PKPM Steel Structure Connection-joint Design Program

针对我国自主研发的PKPM系列钢结构设计软件中节点设计结果不能人为干预的问题以及其设计机制的缺陷,结合钢结构节点设计的专业特点,研发出新的适合于钢框架节点的CAD程序。程序研发采用C++面向对象的开发技术,提供了灵活的人工交互功能,不仅可以实现三维框架的全楼自动节点设计,且设计者可以合并节点、修改节点设计结果并重新校核,使得钢框架节点连接设计变得快速、简便且准确,从而提高工程效率。本文成果已以动态库插件形式作为钢结构连接设计基类库应用于PKPM系列钢结构设计软件各个模块中,取得了良好的应用效果。

Considering the professional features of steel connection-joint design, this paper developed a new computer-aided design (CAD) program which is aiming at solving problems that the connection-joint design results unsuitable for human intervention of the software developed by our country. Program developing and researching is adopted the object-oriented development technique C++ to provide a flexible interactive function which can not only achieve the whole building's automatic connection-joint design of three-dimensional framework but also nodes merging, node design results modification and re-checking by designer. The program can make the connection-joint design of framework fast, simple and accurate to improve engineering efficiency. The achievement has been used in each module of the PKPM series steel structure design software as base class library of steel connection design in dynamic library plug-in form and obtained good application effects.
