摘要
屈曲约束支撑既能在多遇震下为结构提供抗侧刚度,又能在罕遇震下屈曲耗能,减小主体结构损伤。本文结合某办公楼设计实例,介绍了屈曲约束支撑的特点和设计要点,并利用SAUSAGE软件进行了罕遇地震下的动力弹塑性时程分析。结果表明,屈曲约束支撑具有良好的抗震性能,可用于高烈度区、承担较为重要功能属性的建筑中。
Buckling restrained braces can not only provide lateral stiffness for structures under frequent earthquakes,but also dissipate energy under rare earthquakes and reduce damage of main structures.This paper combines the design example of an office building,introduces the characteristics and design points of buckling restraint braces,and uses SAUSAGE software to carry out dynamic elasto-plastic time history analysis under rare earthquakes.The results show that the buckling restraint braces have good seismic performance and can be used in high-intensity areas and buildings with more important functional attributes.
