摘要
对在ANSYS中模拟混凝土徐变的方法进行探讨,并利用有限元分析软件ANSYS对20根钢-混凝土组合箱梁的短期和长期荷载效应进行分析计算,主要讨论混凝土强度、栓钉的布置等参数对钢-混凝土组合箱梁考虑徐变时的受力性能影响。
The method of simulation of concrete creep in the ANSYS are discussed and analyzed in this paper, the short-term and long-term load effect to 20 steel-concrete composite box girder are analyzed and studyed, the performance of using different concrete strength, bolt arrangement of nails and other parameters on the steel-concrete composite box girder considering creep are discussed.
