空间计算理论在铰接板桥横向分布系数计算的探讨

         

摘要

目前对于装配式空心板桥的横向分布系数计算一般采用铰接板法,然而该方法认为所有主梁的刚度是相等的,这与实际不符.实际中边梁带有悬臂,则边梁刚度与中梁不等,其横向分布系数与刚度相等的计算结果有差异.采用空间计算理论(梁格法、板壳元法)计算得到横向分布系数,与铰接板法、边梁与内梁刚度不等的横向分布计算方法的结果进行比较分析,给实际工程的设计提供参考.%At present, articulated slab method is applied in calculation of transverse distribution coefficient for prefabricated cellular slab bridge. The stiffness of ali girders is considered equal in this method, In fact the difference in stiffness between centre sill and the side beams leads an inaccurate result. Spatial calculation FEM is applied ,and the calculation result compared with articulated slab method and the method considering the difference between side beam and inside beam is also presented. This method can provide significant reference for engineering application.
