摘要: 汕頭市澄海區(qū)人民醫(yī)院新建門診醫(yī)技住院樓位于高烈度區(qū),地震作用大,設(shè)計(jì)復(fù)雜程度高,需采用消能減震設(shè)計(jì)方法。 從可實(shí)施性、減震效果和經(jīng)濟(jì)性幾方面進(jìn)行比選,黏滯消能器減震方案是較優(yōu)方案;詳細(xì)介紹了黏滯消能器減震設(shè)計(jì)流程及分析結(jié)果。 經(jīng)多遇地震作用下彈性分析和罕遇地震作用下彈塑性分析,黏滯消能器可為主結(jié)構(gòu)提供附加阻尼 5%,不提供附加剛度,大幅降低地震作用下剪力,滿足框架-剪力墻結(jié)構(gòu)的二道防線設(shè)計(jì)要求。

Abstract: The newly-built outpatient medical technology inpatient building of Chenghai District People’ s Hospital inShantou is located in the high seismic fortification intensity region with large seismic action and high design complexity,which should addopt energy-dissipated design method. Comparing and selecting from the aspects of feasibility, dampingeffect and economy, the damping scheme of viscous energy dissipator was the best scheme. The design process and analysisresults of viscous energy dissipator were introduced. Through the elastic analysis under the frequent earthquake and theelastic-plastic analysis under the rare earthquake, the viscous energy dissipator can provide additional damping ratio of 5%for the main structure without providing additional stiffness, which greatly reduces seismic shear forces and meets the designrequirements of the two defense lines of the frame-shear wall structure.

Keywords:high seismic fortification intensity region; energy-dissipated design; viscous energy dissipator; elastic-plastictime-history analysis
