新疆高烈度地区A中学教学楼建设消能减震设计研究

Research on Energy Dissipation and Seismic Reduction Design for Construction of Middle School A Teaching Building in High Intensity Areas of Xinjiang

高烈度区域更易受到地震影响。研究高烈度区域教学楼消能减震设计有助于后期恢复、减少震后损失,提升生存保障。本文以A中学教学楼为研究对象,分析消能减震目标,采用规范消能减震技术及墙体黏滞流体阻尼器方案。研究结果表明,设防地震作用下教学楼主体弹性,粘滞流体阻尼器在中震下就开始屈服耗能,等效附加阻尼比平均值X向4.56%,Y向6.49%,能够满足3%附加阻尼比的要求,粘滞流体阻尼器效果明显。

High intensity areas are more susceptible to the impact of earthquakes.Studying the energy dissipation and seismic reduction design of teaching buildings in high-intensity areas can help with later recovery,reduce post-earthquake losses,and enhance survival security.This article takes the teaching building of Middle School A as the research object,analyzes the energy dissipation and seismic reduction goals,and adopts standardized energy dissipation and seismic reduction technology and wall viscous fluid damper scheme.The research results show that under seismic fortification,the main body of the teaching building is elastic,and the viscous fluid damper begins to yield and dissipate energy under moderate earthquakes.The average equivalent additional damping ratio is 4.56%in the X-axis and 6.49%in the Y-axis,which can meet the requirement of 3%additional damping ratio.Therefore the effect of the viscous fluid damper is significant.
