Abstract:To effectively improve the seismic performance of roofs in buildings and save the construction cost, the seismic performance of the roof of a long-span steel-wood hybrid structure is deeply studied based on an engineering case. The seismic response and tension control stress of pre-stressed cables are determined according to five test parameters, namely, the lateral stiffness ratio, the estimation of seismic action, the setting of bearing capacity, the checking of seismic deformation, and the connection and foundation design. The hybrid roof designed in this study ensures that the roof structure can be subjected to frequent and rare earthquakes. Based on an engineering example, the seismic performance test of a long-span steel-wood hybrid structure roof is carried out according to the effective work. The experimental performance test results show that the seismic performance of the long-span steel-wood hybrid structure roof is stronger than that of a single-structure roof. Moreover, the case study shows that the seismic performance of the inner column is weaker than those of other members of the long-span steel-wood hybrid structure under multidimensional earthquakes.
