Combining the steel structure corridor added between two buildings in the actual project,designing the support bracket,using the finite element software ANSYS to establish two types of bracket calculation mechanical models,setting up contact elements,simulating the stress state of the post steel bracket nodes,and obtaining the strain and displacement of each part of the bracket,as well as the failure mechanism of the bracket and the failure form of each component;Comparing the calculation results of the two models,the ultimate bear-ing capacity and displacement deformation of the I-shaped bracket are better than those of the double ribbed bracket.However,the concen-trated stress of the double ribbed bracket at the junction of the steel top plate and anchor plate is more uniform.It is recommended to priori-tize the use of the I-shaped bracket in the design.The top and second row anchor bolts are key components of the node,which yield first.As the load increases,the middle row anchor bolts also gradually yield.
