摘　　要：文章以某位于高烈度地区的医院塔楼结构设计为研究背景,对其采用黏滞阻尼器、黏弹性阻尼器作为耗能装置,进行消能减震设计分析。得出以下结论:通过设置合理黏滞、黏弹性阻尼器,可以考虑其提供的等效阻尼比,进行简化计算分析;通过恰当地安装阻尼装置,可以显著提升原有结构关键部位的抗震能力。当遭遇多遇或罕遇地震之际,建筑结构内的关键、重要构件以及薄弱部位的损伤能够得到有效地减弱,让结构具备更好的抗震性能与延性。Takes the design of a high-intensity hospital tower structure as its research background and conducts an energy-dissipating seismic design analysis using viscous dampers and viscoelastic dampers as energy-consuming devices.The following conclusions are drawn:By reasonably arranging viscous and viscoelastic dampers,their provided equivalent damping ratio can be considered for simplified calculation and analysis;By properly installing damping devices,the seismic capacity of key parts of the existing structure can be significantly enhanced.When encountering frequent or rare earthquakes,the damage to critical and important components as well as weak parts within the building structure can be effectively reduced,allowing the structure to have better seismic performance and ductility.
