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 and function of CAD system of inverted T-type prestressed cap girder. It takes into account the characteristics of designers using CAD means to carry out engineering design. It integrates the analysis and calculation, the construction design drawing formation, the graphical interaction modification and the data model management, fulfilling the requirements of using CAD high quality and high speed to complete the engineering design. The system can be used to complete the design of the semi-automatic construction drawings of single-and double-column double-cantilevered inverted T-type prestressed tarpaulins, the analysis of reinforcement design and various checking and analysis. Complete output drawings, in line with the construction design requirements.
