The belt truss joints have many features, including huge mass, thick steel plates, more steel members and so on. The design principles for the belt truss joints of the mega structure system were introduced. Two types of stiffening plates were analyzed and compared to find a more appropriate stiffening plate through using the general finite element software ABAQUS. Considering the combined action of concrete and steel, the mechanical performance of the joints was analyzed under seismic action. The result shows the performance of joints with the horizontal stiffening plate is better than that of the joints with vertical stiffening plate. Joints with horizontal stiffening plate can meet the performance requirement under seismic action.Keywords: mega structure; belt truss; joint; stiffening plate; shear deformation作者簡介：郭峰，碩士，一級注冊結(jié)構(gòu)工程師，Email：guo.feng@ccdi.com.cn。參考文獻［1］HIBBITT, KARLSON.
