摘要
阐述剪力-柔性梁格法的基本理论,应用MIDAS/Civil对钢箱梁桥和混凝土箱梁桥建立梁格模型和单梁模型,通过计算,得到钢箱梁和混凝土箱梁在荷载作用下的竖向位移,验证了梁格法能较好地模拟钢箱梁桥和混凝土箱梁桥,计算结果满足工程精度。
The article sets forth the basic theory of the shearing force-flexible beam grillage method,and uses MIDAS/Civil to build the beam grillage model and simple-beam model for steel box-beam bridge and concrete box-beam bridge.After the calculation,the vertical displacement is given for the steel box beam and concrete box beam under the loading action so as to validate that the beam grillage method can better simulate the steel box-beam bridge and concrete box-beam bridge.The calculation result can satisfy the engineering precision.
