Abstract:Taking the reinforced outer frame structure system as the research object, the force characteristics of the reinforced outer frame structure were introduced, and the main factors affecting the mechanical characteristics of the structure were studied. The influence of the column spacing of the inner and outer frame columns on the structural stiffness and yield bearing capacity was analyzed, and the economic and seismic performance of different structures under the same lateral stiffness were compared. Finally, the application of the reinforced outer frame structure in  Shenzhen Pacific Finance Building was introduced. The results show that the application of the reinforced outer frame structure in the project saves more than 10% of the material compared to the conventional frame-core tube structure system.

Keywords:reinforced outer frame; structural system; parameterized; saving material
