预应力倒T盖梁的半自动设计

Semi-automatic Computer Aided Design of Prestressed Concrete Inverted T Beams

本文介绍了倒T型预应力盖梁的计算机辅助设计系统的总体结构及其功能。它考虑了设计人员利用CAD手段进行工程设计的特点,把分析计算,施工设计图的形成,图形交互修改及数据模型管理融为一体,实现了利用CAD高质量、高速度完成工程设计的要求。使用本系统可以完成单、双柱双悬臂倒T型预应力盖染的配束、配筋分析设计,及各种验算分析,并通过设计人员的人机交互手段进行“半自动”施工图设计,输出图纸齐全,符合施工设计要求。

This paper introduces the general structure & function of a CAD system for inverted T beams for bridge structures. Having taken the characteristics of design procedure with computer into account, this system integrates structural analysis, construction drafting, interactive graphics modification & data model management. It can meet various needs of structural designs with both high speed & high quality. This system is suitable to double cantilever inverted T beams with one column or two. It can also be used to complete mechanical analysis for steel bars and stays setting & stress checking. A series of construction drawings can be obtained interactively by this paper's method. This system finally outputs all drawings of an inverted T beam through HP potter, which can satisfy the regulations of COAD and be directly applied to engineering construction.
