【摘要】 根据《建设工程抗震管理条例》，位于高烈度设防区的新建学校，需采用隔震减震等技术以保证发生本区域设防地震时能够满足正常使用要求。苏宿园区第三所义务教育学校位于高烈度设防区，各建筑单体采用混凝土框架结构，并附加减震技术（屈曲约束支撑或黏滞阻尼墙）。技术难点在于中震反应谱法等效线性化结构设计难以满足抗震性能目标，受建筑平面限制可布置减震装置的位置相对有限。文章中的结构设计方法采用非传统的基于弹塑性时程分析结果，并对减震装置的布置策略进行了研究，针对教学楼单体开展子结构振动台试验，研究结构抗震性能。分析与试验结果表明，高烈度设防区学校建筑采用混凝土框架结构与组合减震技术的融合是一种相对高效的解决方案。更多还原

【Abstract】 According to the Regulations on Seismic Management of Construction Projects, newly built schools located in high-intensity seismic fortification areas must adopt seismic isolation and damping technologies to ensure that they can meet normal usage requirements during earthquakes corresponding to the local fortification level. The third compulsory education school in the Suzhou-Suqian Industrial Park is located in a high-intensity seismic fortification area. Each building unit uses a concrete frame structure with additional damping technologies(buckling-restrained braces or viscous damping walls). Given the technical challenges such as the inability of equivalent linear structural design methods based on the moderate earthquake response spectrum to meet seismic performance targets and the relatively limited positions available for installing damping devices due to building layout constraints, this paper adopts a non-traditional structural design approach based on elastoplastic time-history analysis results and studies the layout strategy of the damping devices. Substructure shaking table tests were conducted on an individual teaching building to study structural seismic performance. Analysis and test results indicate that the combination of concrete frame structures and combined damping technologies in schools located in high-intensity seismic fortification areas is a relatively efficient solution.更多还原
