Abstract

Abstract

In steel frame-tube structures (SFTSs), the plastic hinges usually form at column-ends before beam-ends due to the low span-to-height ratio of deep beams, which can lead to lower ductility and energy dissipation capacity of the SFTSs. To address this problem, a replaceable shear link, acting as a ductile fuse at the midspan of deep beams, was proposed. In order to evaluate this proposal, buildings were designed to compare the seismic performance of SFTS-RSLs and SFTSs. Several sub-structures were selected from the design buildings, and finite element models (FEMs) were established to study their hysteretic behaviors. The nonlinear static pushover analysis and dynamic analysis were undertaken in comparing the seismic performance of the FEMs for each building. The results indicated that the SFTS-RSL and SFTS had similar initial elastic stiffness. Compared with the SFTS, the SFTS-RSL had lower yield strength and maximum strength, but higher ductility and energy dissipation capacity. The SFTS-RSL had lower interstory drift compared with the SFTS. Placing a shear link at the beam mid-span did not increase shear lag effects for the structure. The SFTS-RSL concentrated plasticity on the shear links. Other structural components remained elastic during the seismic loading. It could be expected that the SFTS-RSL would be a reliable dual resistant system, which could offer the benefit of being able to repair the structure rapidly by replacing the damaged shear links after earthquakes.
