摘　　要：邯郸市科技中心主楼地上25层,主体高度99.2 m,采用框架-剪力墙结构。为保证建筑立面及结构扭转刚度的要求,在主楼四角设置支撑。采用ETABS软件对布置不同数量屈曲约束支撑时的耗能效果进行了弹塑性时程分析。结果表明,建筑中采用屈曲约束支撑和普通钢支撑相结合的布置方案可以实现预期的减震效果和降低工程造价。The main building of Handan Science and Technology Center has 25 floors on the ground,the main body height is 99.2 m,and the frame shear wall structure is adopted.To ensure the building facade and structural torsional stiffness requirements,brace are set at the four corners of the main building.ETABS software was used to analyze the energy dissipation effect when different amounts of buckling-restrained brace were arranged.The results show that the expected shock absorption and cost reduction can be achieved by using the layout scheme of buckling-restrained brace and ordinary steel brace.

关 键 词：屈曲约束支撑 消能减震 时程分析
