某高层剪力墙住宅结构减震分析与设计*闫维明,王 瑾,张向东,苏 亮,王维凝(北京工业大学工程抗震与结构诊治北京市重点实验室,北京 100124)[摘要]将铅剪切阻尼器应用于某高层剪力墙住宅结构的减震分析与设计中,经过多次试算分析得到了阻尼器的优化布置方案。小震下的弹性时程分析和大震下的静力弹塑性分析结果表明,铅剪切阻尼器的减震率达到了40%,可以使该结构的抗震能力约提高1度。对布置阻尼器后的结构竖向承载力进行了验算,并对有关部位、附加剪力墙配筋和预埋件进行了设计。[关键词] 耗能减震;剪力墙;住宅结构;铅剪切阻尼器中图分类号:TU318.83文献标识码:A文章编号:1002-848X(2011)01-0059-04Energy dissipation analysis and design of a tall residential building with shear wallsYan Weiming, Wang Jin, Zhang Xiangdong, Su Liang, Wang Weining(Beijing Key Lab of Earthquake Engineering and Structural Retrofit, Beijing University of Technology, Beijing 100124, China)Abstract:The lead shear dampers were used in a tall residential building with shear walls to reduce the earthquake-induced vibration. The optimum positions and the amount of the dampers were determined through series calculations. The results of the linear time-history response analysis under frequent earthquakes and the non-linear static pushover analysis under rare earthquakes show that the responses of the building can be reduced by 40%. The vertical load-carrying capacity of the structure was checked, and the linking areas and the corresponding embedded parts were designed as well.Keywords:energy dissipation; shear wall; residential building; lead shear damper国家科技支撑计划课题(2006BAJ03B06),高等学校博士学科点专项科研基金(20060005004),北京市属市管高校八才强教计划资助项目。作者简介:闫维明,教授,博士生导师,Email:yanwm@bjut.edu.cn。参考文献[1]孟春光. 粘滞阻尼器减震结构设计方法及计算实例[J]. 建筑结构, 2009,39(S2): 185-189.[2]张春科. 板式铅剪切阻尼器的工程应用与转动式铅剪切阻尼器研究[D]. 北京:北京工业大学,2008.[3]闫维明,刘猛,李振宝,等. 新型铅剪切阻尼器的数值模拟实验研究[J]. 北京工业大学学报,2008,34(21):1286-1290.[4]闫维明,张春科,彭凌云,等. 一种剪切型铅阻尼器及其在某火电厂房中的应用[J] . 工业建筑,2008,38(7):41-44.[5]马春和,余建星,梁凤岭. 某高层住宅楼的改造加固设计与施工[J]. 建筑结构,2009,39(S2): 271-273.
