摘要

摘要: 近年来对K型偏心支撑钢框架的研究多是未考虑楼板的影响，将钢框架与楼板结合形成带组合梁的K型偏心支撑钢框架，推导在考虑楼板影响下带剪切型耗能连接的钢框架初始刚度、极限承载力算式。并利用ABAQUS软件建立17个模型分析其在单向荷载作用下的各项性能，结果表明：组合楼板可以提升钢框架的整体性能，改善水平力在结构中的传递，从而大幅度提高结构的各项抗震性能。基于楼板作用下带剪切型耗能连接K型偏心支撑钢框架所推导算式的计算结果，与ABAQUS模拟结果相比，误差基本都在15%以内，具有较好的吻合，为后续带楼板的剪切型耗能连接K型偏心支撑钢框架的承载力与刚度计算分析提供一些算式参考。

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.
