Abstract

Modularized prefabricated steel structure has some obvious advantages, such as fast construction, industrial-scale production and environment-friendliness. Although it has been used for low-rise buildings, its applications in high-rise buildings are quite less. The elastic-plastic time-history analysis under rare earthquake conditions is performed on a 30-floor building. The changing law of the base shear force, the story drift angle, the stress, the damage characteristics, etc. are studied. According to the theoretical analysis, the finite element simulation and the model test, the design methods and the relevant formulas regarding the elastic and elastic-plastic properties of the beam-column connection joints, the column flange joints and the inclined brace joints are proposed in this paper. The control parameters for the structural design are also discussed. This paper provides an important reference for the research and design of the same type of modularized prefabricated high-rise steel structures, and the design method has been compiled into design specification.
