l前言以往铰接板横向分配系数的计算公式都是在每块板的几何、物理参数一样的基础上推导而得到的，即各板的板宽、抗扭刚度、抗弯刚度都一样。但我们经常会遇到同一跨径内板的参数不相同这样的问题。有很多桥的中板与边板宽度不相同，相应的抗扭惯矩、抗弯惯矩也就不同，对参数 l Foreword In the past, the formulas for calculating the lateral distribution coefficient of hinge plates were deduced on the basis of the geometric and physical parameters of each plate. That is, the plate width, torsional stiffness and bending rigidity of each plate are the same. But we often encounter the same span of the board parameters are not the same problem. There are many bridge plate and the width of the edge is not the same, the corresponding moment of inertia, moment of inertia will be different, the parameters
