Abstract:In the structural design of Shougang studio, according to the requirements of architectural layout and function, the studio was divided into two parts by sliding connections: the large studio and the small and medium-sized studio. The structure of the large studio was complex and there were many irregularities. Two kinds of analysis software were used to calculate and check the whole structure under the frequent earthquake. Elastic dynamic time-history analysis was used to conduct the envelope design. According to the D-class performance target, the structural performance under fortification and rare earthquakes was checked. The dynamic elastoplastic time-history analysis under rare earthquake was carried out by SAUSAGE software, to ensure that the structure could not collapse down under large earthquake. Finite element stress analysis was carried out for large opening and narrow floor slab to ensure the plane stiffness of the floor slab.
Keywords:Shougang studio;performance design;elastoplastic time-history analysis;stress analysis of floor slab
