板壳模型在整体现浇板设计中的应用

为了研究板壳模型在整体现浇板桥设计中的应用,通过使用有限元分析软件Midas/civil建立板壳模型,计算得出相对于等效梁格法更为精确,更为接近实际情况的结果。并根据提取板单元的纵横向弯矩以及主弯矩进行配筋设计。板壳模型的计算结果既包括了结构的整体受力效应,又包括了结构的局部受力效应,因此对计算结果要进行局部削峰。

Design Application of Plate-shell Model in Cast-in-place Slab Bridges

In order to research the design application of plate and shell model in cast-in-place slab bridge,this paper established plate model by finite element analysis software Midas/civil,and the calculation results were more accurate and closer to the actual situation than that of grillage method.The reinforcement design was carried on according to the longitudinal moment,transversal moment and primary moment of plate element.Plate and shell model calculation result.Not only the whole stress effect,but the local stress effect of the structure is including in the results.So the calculation results should be locally peaked.
