文章基于有限元综合程序ANSYS,采用APDL和UIDL语言编写针对桥梁结构计算与分析的二次开发模块。模块包括静力计算和抗震计算两部分。静力计算模块结合桥梁结构和现行设计规范的特点,计算工况包括了2004新规范的活载计算内容。抗震模块报括谱分析和时程分析两部分,可以方便的选择反应谱以及地震波,同时可以进行幅值的自动调整。对于大跨度桥梁,能够选择进行多点激震和考虑行波效应的地震影响分析。模块计算中所需参数根据对话框输入,工程人员应用起来比较方便。
Based on the finite element integrated program ANSYS, this paper uses APDL and UIDL language to write the secondary development module for bridge structure calculation and analysis. The module includes two parts: static calculation and anti-seismic calculation. Static calculation module combined with the characteristics of the bridge structure and the current design specifications, calculation conditions include the 2004 new specification live load calculation content. Anti-seismic module includes spectral analysis and time history analysis of two parts, you can easily select the response spectrum and seismic waves, while the amplitude can be automatically adjusted. For long-span bridges, seismic effects analysis with multiple point shocks and traveling wave effects can be selected. The required parameters in the module calculation are input according to the dialog box, and the engineering staff are more convenient to use.
