基于Ansys有限元软件的钢箱梁人行天桥主梁结构安全验算实例分析

Analysis of Examples of Safety Checking of Main Girder Structure of Steel Box Girder Pedestrian Bridge Based on ANSYS Finite Element Software

通过对某钢箱梁人行天桥为研究对象,运用桥梁博士V3.5.0软件及Ansys有限元软件,对钢箱梁人行天桥主梁结构的强度、稳定性、挠度及自振频率进行了验算,为类似钢结构人行天桥的结构设计与计算提供依据。

Based on a steel box girder pedestrian bridge as the research object,the strength,stability,deflection and natural frequency of the main girder structure of the steel box girder pedestrian bridge are checked by using the software of Dr.Bridge V3.5.0and Ansys finite element software,which provides a basis for the structural design and calculation of similar steel structure pedestrian bridge.
