Modularized prefabricated steel structures have certain obvious advantages, i.e., rapid construction, industrial-scale production and pro-environmental aspects, and are the main method in industrialization of steel structures. Although applications of these structures have been reported all over the world, in most cases, the steel structural systems are only suitable for low-rise buildings, and their application in high-rise buildings is quite limited. This paper proposes a new type of modularized prefabricated high-rise steel frame structure with inclined braces. Based on the T30 hotel building, the mechanical properties, failure mode, failure mechanism and elastic-plastic development laws are investigated by using the elastic design of a structure under various load conditions, the analysis of the internal force and displacement responses under frequent earthquakes via the response spectrum method and linear time-history analysis, the static elastic-plastic pushover analysis under rare earthquake conditions. According to finite element simulations and testing, elastic and elastic-plastic structural design methods are proposed in this paper. This work provides an important reference for research and design of the same type of modularized prefabricated high-rise steel structures, and the design method has been compiled into design specification.
