【摘要】 为准确了解新光大桥施工过程中的三维受力状况,建立以块体单元、板单元、梁单元及杆单元组成的有限元模型,利用通用有限元程序Strand7并通过引入API的方法进行施工过程的仿真计算,给出仿真分析结果,指导主桥整体施工。施工过程中的实测结果与仿真计算结果相吻合,证明了仿真分析方法及结果的正确性。更多还原

【Abstract】 To have an exact understanding of the three-dimensional mechanical behavior of the main bridge of Xinguang Bridge in its global construction process,this paper establishes a finite element model that incorporates the solid,plate,beam and link elements,makes the simulation calculation of the construction process,using the universal finite element software Strand7 and the API method and also gives the results of the simulation analysis for the purpose of guiding the construction of the bridge.The measurements obtained in the construction process agree with those of the calculation and prove that the method and results of the analysis are correct.更多还原
