摘要
随着社会的发展,目前很多大型综合场馆为了满足不同建筑使用功能,往往设计成大跨度,大开间的复杂结构体系,因此整体抗震性能大打折扣,尤其在高烈度地区。为了满足当前建筑结构的抗震需求,主体结构需引进抗震减震措施,以降低地震对建筑的破坏作用并保证结构在地震作用下的安全性。通过对位于高烈度区海口体育馆看台结构部分传统抗震框架—剪力墙结构体系与减震方案框架—屈曲约束支撑以及黏滞阻尼墙结构体系在多遇地震,设防地震以及罕遇地震作用下各抗震指标的对比分析,表明屈曲约束支撑以及黏滞阻尼墙在不同地震作用下,耗能充分减震效果明显,有效减小了主体结构构件的损伤,体现了良好的耗能机制,为消能减震技术应用于大型体育馆工程提供了参考。
With the development of society,many large-scale comprehensive venues are often designed as complex structural systems with large spans and large bays in order to meet different functional requirements.Therefore,the overall seismic performance is greatly reduced,especially in high-intensity areas.In order to meet the current seismic requirements of building structures,the main structure needs to introduce seismic and damping measures to reduce the damage caused by earthquakes to the building and ensure the safety of the structure during earthquakes.In this paper,the comparative analysis of various energy consumption indicators between the traditional seismic frame-shear wall structure system and seismic damping scheme frame-buckling restrained bracing and viscous damping wall structure system located in the high-intensity area of Haikou Gymnasium under the action of frequent earthquakes,fortification earthquakes and rare earthquakes shows that the buckling restrained brace and viscous damping wall have sufficient energy consumption and damping effect under different earthquakes,which effectively reduces the damage of the main structural members and reflects a good energy consumption mechanism.It provides a reference for the application of energy dissipation and shock absorption technology to large-scale gymnasium projects.
