摘要
Abstract
The rigid zone of box culvert refers to the region where the structure intersects at the node, and the relative bending stiffness of the zone is infinitely large. It exhibits non-deformable properties, which results in the deformation of the structure Impact. In order to study the rigid zone of box culvert, the characteristics of force and deformation of box culvert are analyzed, and the rigid zone and its judgment method are determined based on the basic parameters of box culvert. Haunch layout parameters as taken as variables to analyze the law of rigid domain effect of box culvert structure. The ratio between the rigidity domain and the structural dimension of the roof and side walls, and the optimum slope of the haunch layout are determined by analysis. With the effect of the rigid zone, the deformation and internal force are smaller and the amount of steel bar can be reduced to lower the project cost.关键词
