预应力砼箱梁极限承载能力的非线性有限纤维梁段元分析

Nonlinear Finite Fibre Beam Element Analysis of the Prestressed Concrete Box-Girder Structure

为更精确有效的分析预应力砼箱梁结构体系的极限状态特性,建立了考虑双非线性的有限纤维梁段元法,同时进行了原形梁极限承载试验以验证该方法精度.

In the ultimate bearing capacity calculation of prestressed concrete box girder structure, the bi-nonlinear finite fibre beam element method is suggested. The beating capacity experiment of the original girder model was carried out to investigate the feature of its limit state and to validate its applicability and accuracy.
