Abstract: Static and dynamic stability analysis method, value of the safety factor, critical load determination criteria for truss string structures were studied based on Tianjin Meijiang Convention and Exhibition Center project. Determination method of performance-based strength failure critical load for truss string structures was proposed considering engineering seismic design. Seismic design method based on dynamic stability for truss string structure under strong earthquake was discussed. The evaluation for static and dynamic stability of truss string structure for Tianjin Meijiang Convention and Exhibition Center had been carried out. The results show that the project has good seismic performance.
Keywords:truss string structure; static stability; dynamic stability; critical load; criterion
