摘　　要：以某学校图书馆采用的型钢混凝土框架剪力墙-钢桁架混合结构为工程实例,作为重点设防类建筑,为控制结构构件尺寸、减小结构地震响应、提高结构抗震性能,对混合结构进行消能减震设计,并用SAUSG分析结构在8度(0.2g)地震作用下的地震响应。结果表明:设防地震作用下,消能减震混合结构保持弹性工作;设防和罕遇地震作用下的最大层间位移角在X向分别为1/838和1/499,在Y向分别为1/629和1/248,均满足规范要求;罕遇地震作用下,消能器的滞回曲线饱满,耗散大量地震能量,体现了良好的减震效果,为结构主体提供了安全保障。The section steel and concrete frame shear wall-steel joist hybrid structure adopted in a school library is served as an engineering case for study.As a key defended building,the hybrid structure is designed with energy dissipation and seismic damping to control the size of structural members,reduce the seismic response of the structure and improve the seismic performance of the structure,and the seismic response of the structure under the seismic action of 8th degree(0.2g)is analyzed by SAUSG.The results show that:the energy dissipation and damping hybrid structure maintains elastic work under seismic action of defense;the maximum interlayer displacement angle under seismic action of defense and rare earthquake is 1/838 and 1/499 in X direction respectively,and 1/629 and 1/248 in Y direction respectively,both of which meet the specification requirements;the hysteresis curve of the energy dissipator is full under the action of rare earthquake,which dissipates a large amount of seismic energy,reflecting a good seismic damping effect,and provides safety guarantee for the main body of the structure.
