摘要
迄今为止,计算异型桥、斜弯桥等箱梁桥最有效的计算方法就是剪力柔性梁格法。但梁格法毕竟是在满足一定条件的空间问题,因此从建立模型、大量原始计算数据的准备,还是需要比较长的时间。本文对梁格法的历史背景、计算理论及计算方法进行详细的阐述探讨,希望能够对桥梁设计者对梁格法有更加深入明确的认识,并在一定程度上能够推进梁格法的应用。
Up to now,the most effective method for calculating box girder bridges such as special-shaped bridges and skew-curved bridges is the shear-flexibility grillage method.However,the grillage method is a space problem that meets certain conditions after all.Therefore,it takes a long time to build a model and prepare a large number of original calculation data.In this paper,the historical background,calculation theory and calculation method of the grillage method are discussed in detail.It is hoped that this paper can give bridge designers a more in-depth and clear understanding of the grillage method,and to a certain extent,promote the application of the grillage method.
