Influence of Transition Layer Position on Seismic Performance in Multi-Story Buildings of SRC-S Vertical Hybrid Structures

Abstract:

When vertical hybrid structures of steel reinforced concrete-steel (SRC-S) are used in multi-story and tall buildings, the connection between the two structural systems would probably dissatisfy the seismic request because of the abrupt change of stiffness. Setting up a stiffness-transition-layer is an efficient way to improve the seismic performance. In this paper, elastic and elastic-plastic analysis was conducted on a six-floor frame structure by Midas software. In the building, concrete encased shape steel was applied as the transition layer. By comparative analysis, we tried to find out how different transition layer positions could affect seismic performance in SRC-S vertical hybrid structures. Given the results, transition layer position has great influence on the story drift angle, story drift and the development of the plastic hinges. The suggestion on transition layer position was proposed to provide a reference for seismic design.
