本文从我国钢筋混凝土组合T梁公路桥的实际出发,结合系统的室内试验,在确定有关材料参数的情况下,采用了一种精度高、速度快的有限元分析方法。它将整个组合T梁化分成四种单元。文中应用的改进型Wilson元,解决了普通四结点平面元“寄生”剪切问题,因而大大提高了单元的精度。四类元合理模拟了结构各部分的受力特征,使计算优化得以实现,运算机时达到最少。

The article presents a highly accurate and rapid analysis of limited units, based on a series of systematic indoor tests and reinforced concrete T -beam Bridge adopted in our country,with some relevant parameters. It divided the entire T -beam into four units which give an reasonable model structure to show the features of different units under load, and enable ...
