Abstract: Due to the architectural appearance and functional requirements of a multi-story steel structure exhibition hall, the centrally braced steel frame structural system is adopted in the north area of the exhibition hall, and there are many irregularities in the structure. The performance-based seismic design scheme was adopted. For the inner side of the structure, the space grid structure formed by the curtain wall keel was used as the vertical force transmission component, and the whole process of its stability was analyzed, the calculation results show that the structure stablity meets the requirements. After static elastoplastic analysis of the structure under the rare earthquake, it is found that the structure has good seismic performance. The multi-scale analysis of the main joints shows that the joints are basically in elastic working state under rare earthquake.
Keywords:performance-based seismic design; whole process stability analysis; multi-scale analysis; static elastoplastic analysis; temperature stress analysis
