摘要
桥梁荷载试验分析系统BLT是针对桥梁检测试验分析开发的专用软件,能够建立桥梁结构空间有限元模型,运用实体单元和空间梁格法进行静动力试验分析,试验荷载效率计算,查取测点位置的应力和位移理论计算值等。该系统是桥梁检测工作的辅助工具,也可分析宽、弯、斜拉桥梁等空间受力状态。本文详细介绍该系统的整体构思特点、计算原理以及实桥应用算例等。
Bridge load testing analysis system software BLT was developed for bridge detection test analysis. It could establish a threedimensional finite element model of bridge based on solid element or Beam element, to make the static and dynamic test analysis, calculate the test load efficiency, and investigate the theoretical calculations of stress and displacement in the location of the measurement points. This system is a useful auxiliary tool for bridge detection, and also can analyze the spatial force state of the wide, curved, cablestayed bridges. This paper details the characteristics of the overall concept of the system, the calculation principle as well as the real bridge application examples.
