摘　　要：为研究带十字芯板钢管阻尼器的K型偏心支撑框架结构的抗震性能,采用ABAQUS软件分析了阻尼器的削弱比、厚度比、轴压比等因素对该结构抗震性能的影响,研究了结构的变形性能、破坏形态及耗能能力.结果表明:采用十字芯板钢管阻尼器的K型偏心支撑钢框架结构具有优良的变形能力和耗能性能,结构塑性变形与损伤主要集中于阻尼器,能够有效的保护结构的安全.To study seismic performance of K-type eccentric brace with cross core plates steel tube damper, finite element models were built by ABAQUS software to analyze influences of different weakening in steel tube, thickness of the core plates, and axial compression on deformability, failure mode and energy dissipation. The results show that K-type eccentric brace with the proposed damper is advantageous in deformability and energy-dissipation behavior, plastic deformation and damage are concentrated on the damper to ensure the safety of the structure.
