【摘要】 杭州某混凝土框架结构建筑采用黏滞阻尼器进行减震加固设计，分别使用YJK和SAP2000软件进行多遇地震和罕遇地震分析。在多遇地震作用下，结构主体弹性、黏滞阻尼器开始发挥作用。在罕遇地震作用下，结构开始进入塑性，先后出现梁铰和柱铰，满足“强柱弱梁”和位移角要求，且有一定的安全储备。同时各黏滞阻尼器均滞回耗能，显示出良好的耗能能力，可为结构主体提供良好的安全保障，为类似减震加固项目提供参考技术方案。更多还原

【Abstract】 A concrete frame structure building in Hangzhou adopts viscous damper for shock absorption and reinforcement design. YJK and SAP2000 software are used to analyze frequent earthquakes and rare earthquakes respectively. The results of frequent earthquake analysis indicate that the main structure remains elastic and the viscous dampers begin to function. The results of rare earthquake analysis indicate that the structural components begin to enter the plastic phase, satisfying the requirements of "strong columns and weak beams" and displacement angle, and there is a certain safety reserve. Meanwhile, all viscous dampers dissipate energy through hysteresis, demonstrating excellent energy dissipation capabilities and providing good safety guarantees for the main structure. This paper provides a reference technical solution for similar seismic reinforcement projects.更多还原
