| 摘 要： | 由于分析精细、应用简便,平面梁格法已广泛应用于斜弯桥、裤衩高架等异型桥的计算分析中。通过对"Hambly"平面梁格的梁格划分方法与刚度取值的改进,提出更便于杆系有限元软件运用的单层梁格法;通过单层梁格法分析了宽翼缘箱梁的剪力滞效应,并与能量变分法对比,证实了单层梁格法可以有效的计算宽翼缘箱梁剪力滞效应,而这是平面梁格无法解决的。

| Abstract: | The plane grillage method has been widely applied in the calculation and analysis of the oblique,curved and special-shaped bridges because of its fine analysis and convenient application.The article puts forward the single-layer grillage method more easily for the application of member system finite element software by improving the grillage division method of "Hambly" plane grillage and the rigidity calculation.The article analyzes the shear lag effect of wide-flange box beam by the single-layer grillage method,and validates that the single-layer grillage method can efficiently calculate the shear lag effect of wide-flange box beam by comparing with the energy variational method.But it is hard to solve it by the plane grillage method. |
