某单层体育馆减震方案对比与分析

SCHEME DESIGN OF ENERGY DISSIPATION FOR A SINGLE-FLOOR GYMNASIUM

为了响应建设工程抗震管理条例对高烈度设防地区新建学校建筑应当采用减隔震技术来提高抗震性能的要求,文中对实际工程中常见的单层体育馆建筑,分别采用屈曲约束支撑和黏滞阻尼器两种减震装置进行了方案设计,按照云南省抗震设防专项审查的要求分析评价了两种建筑方案的计算结果。结果表明对于单层体育馆,屈曲约束支撑减震难以满足耗能占比的要求,而黏滞阻尼器减震在耗能占比方面要优于屈曲约束支撑。

The regulations on the administration of earthquake resistance in construction projects stipulate the re⁃quirements for the use of seismic isolation or energy dissipation technology in new school buildings in high earth⁃quake intensity area to improve the seismic performance.Buckling-restrained brace and viscous damper scheme for seismic energy dissipation were designed for a common single-storey gymnasium.The results were analyzed and evaluated according to requirements of special review for seismic design in Yunnan Province.The results show that for single-storey gymnasiums,buckling-restrained brace scheme is difficult to meet the requirements of energy con⁃sumption ratio,while viscous damper scheme is better than buckling-restrained scheme in terms of energy consump⁃tion ratio.
