Research on Mechanical Property of Intermediate Diaphragm Arrangement of Skew Curved T-beam Bridge
At present,there is little research on the arrangement of intermediate diaphragms for skew curved T-beam bridges.In order to study the influence of intermediate diaphragm arrangement on the mechanical properties of bridges and optimize the arrangement of intermediate diaphragms for skew curved bridges,this paper combines Dr.Bridge's grillage model to carry out stress analysis of orthogonal and skew bridges with different number of intermediate diaphragms,different spans and different intermediate diaphragm arrangements.The research shows that it is appropriate to arrange two diaphragms for 25 m span T-beam,and three middle intermediate diaphragms for 30 m and 40 m span T-beams.For orthogonal and skew bridges,the mechanical property of the normal arrangement of middle diaphragm is better than that of the oblique arrangement of middle diaphragm.
