Abstract

Abstract

In recent years， research on K-type eccentrically braced steel frames has often neglected the influence of floor slabs. By integrating a steel frame with floor slabs to form a K-type eccentrically braced steel frame with composite beams， this study derived formulas for the initial stiffness and ultimate bearing capacity of the steel frames with shear links under the influence of floor slabs. Additionally， the ABAQRS software was used to establish 17 models to analyze its performance under unidirectional loading. The results showed that the combination of floor slabs improved the overall performance of the steel frame and enhanced the transmission of horizontal forces in the structure， thereby significantly improving its seismic performance. The calculation results based on the deduced formula for the K-type eccentrically braced steel frame with shear links under floor slab action were compared with the ABAQUS simulation results. The error of the derived formula was found to be within 15%， showing good agreement. This provides some formula references for calculating and analyzing the bearing capacity and stiffness of K-type eccentrically braced steel frames with shear links and floor slabs.
