摘　　要：针对消能技术在奥林匹克体育中心体育场加固改造工程中的应用。讨论了消能减震结构的分析及设计方法和设计思路、液体粘滞阻尼器的参数选择、布置方式、消能结构构件设计方法等问题。根据不同加固方案的对比分析,在抗震加固工程中采用消能减震装置可明显减小地震力,并减小新加支撑附加给既有结构的地震力。消能减震设计宜根据建筑功能要求、结构变形形式布置消能装置。Application of energy dissipation device in Stadium of Olympic Center is introduced. Method of structural analysis and design of structure with energy dissipation device, determination of device parameters, scheme of installation, design method of components are discussed. By results of contrast between different retrofit schemes, it can be concluded that application in structural retrofit can reduce structural seismic response and the internal seismic force of component from brace newly-added significantly. In energy dissipation design of structure, the layout energy dissipation device should be planned according to demand of architectural demand and structural deformation type.
