摘要: 汕头市澄海区人民医院新建门诊医技住院楼位于高烈度区,地震作用大,设计复杂程度高,需采用消能减震设计方法。 从可实施性、减震效果和经济性几方面进行比选,黏滞消能器减震方案是较优方案;详细介绍了黏滞消能器减震设计流程及分析结果。 经多遇地震作用下弹性分析和罕遇地震作用下弹塑性分析,黏滞消能器可为主结构提供附加阻尼 5%,不提供附加刚度,大幅降低地震作用下剪力,满足框架-剪力墙结构的二道防线设计要求。

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.
