某整体式现浇空心板梁静载试验模型对比研究

Comparative Study on Static Load Test Models of Integral Cast-in-place Hollow Slab Beam

针对整体式现浇空心板梁,桥梁设计中一般都是采取单梁法进行设计,但是单梁法对于桥梁整体式现浇空心板梁荷载试验存在一定局限性,无法反映桥梁横向受力分布特征。对此,文章建立了单梁模型及梁格模型,通过现场实测数据对比两种模型理论计算结果,提出整体式现浇空心板梁建模方法,为整体式现浇空心板梁静载试验建模提供参考。

For integral cast-in-place hollow slab beam, single beam method is generally adopted in bridge design, but single beam method has some limitations for load test of integral cast-in-place hollow slab beam, which can not reflect the transverse stress distribution characteristics of the bridge.In this paper, the single beam model and the grillage model are established. The theoretical calculation results of the two models are compared by the field measured data. The modeling method of the integral cast-in-place hollow slab beam is proposed, which provides references for the static load test modeling of the integral cast-in-place hollow slab beam.
