摘要
我国已建带铰T构桥梁数目较多,且产生了不少病害,部分病害均与剪力铰有关,但其受力情况难以明确,利用ANSYS有限元软件建立剪力铰结构局部模型,分别研究剪力铰在静力和疲劳作用下各部位的应力分布情况,并提出剪力铰维修、加固的建议,为剪力铰的改进提供参考。
China has built a larger number of configurations with joint T bridge and generates a lot of diseases,some diseases are related to shear hinges,but it is difficult to define the forces,using ANSYS finite element software to establish local model shear hinge structure respectively,in the study of shear hinges static and fatigue the stress distribution of the parts,and proposed shear hinge repair,reinforcement proposals provide a reference for the shear hinge improvements.
