高层建筑结构初步设计的专家系统

本文通过对结构初步设计本质和内容的分析，提出了高层建筑结构初步设计的专家系统HIPRED的原型系统．它是一个综合集成系统：通过人工神经元网络（ANN）技术存贮专家的设计经验来确定高层建筑的结构体系；利用能连续化地反映高层建筑结构参数分布的基于悬臂梁的结构简化模型，并结合常微分方程求解器COLSYS很好地从速度和精度两方面的匹配来进行力学反应分析；通过人机交互和知识库的引入，系统能够对设计的结构反应参数（位移、周期和地震为）做出评价及对结构做出相应的修改．HIPRED能够帮助设计者在一个较高层次上进行高层建筑结构的初步设计。HIPRED是在Windows环境下，采用面向对象的编程技术（OOP），用C＋＋编写的。

EXPERT SYSTEM OF STRUCTURAL PRELIMINARY DESIGN FOR HIGH-RISE BUILDINGS

In the paper, the essense and contents of structural preliminary design for highrise building s is discussed. An expert system of structural preliminary design for high-rise buildings, HIPRED, is presented. It is an integrated system in which some advanced artificial intelligence (AI) techniques, such as artificial neural networks (ANN) and knowledge base (KB) were incorporated. A fast mechanical analysis method based on a cantilever beam model and a powerful ordinary differential equations solver COLSYS were introduced into the system. The integrated expert system can help engineers find a better high-rise building preliminary scheme.
