蜂窝梁强度破坏补强方法研究
Study on the Reinforcing Methods for the Strength Failure of Castellated Beams
摘要
Abstract
This paper mainly investigates the reinforcing methods for the bending-shear or shear strength failure of hexagonal castellated beams under the concentrated or uniform load.For the bending-shear failure,it puts forward the reinforcing method of plugging two holes in the middle with the steel plates of the same thickness.For the shear strength failure,it puts forward the reinforcing method of plugging two holes at the ends with the steel plates of the same thickness.The bearing capacity and deformation of the specimens before and after reinforcement was simulated and analyzed by the ABAQUS software.The result shows that the bearing capacity of specimens after reinforcement has been improved obviously by more than 10%,and the bending deflection has been effectively controlled,with the deformation reduced by 10%～20%.This reinforcing method is convenient in construction,and is applicable to the structures with relatively large load and strict deformation requirements.关键词
