青岛华润中心悦府某超高层剪力墙住宅结构设计

Structural design of a super high-rise shear wall residential building in Joyful Mansion of Qingdao China Resources Center

青岛华润中心悦府8#楼为典型的超高层剪力墙住宅,地下部分与周边结构关系复杂,平面较不规则,刚度偏心严重,为钢筋混凝土超限结构。首先介绍了其地基与基础设计、结构选型,分析了结构超限情况,确定了抗震性能目标。随后,进行了多遇地震作用下的结构弹性分析和罕遇地震作用下的动力弹塑性分析,根据分析结果对不同地震水准下的承载力和变形进行了设计。最后,针对高度、扭转位移比和高宽比等超限问题,探讨了各关键问题的应对措施。

No.8 building in Joyful Mansion of Qingdao China Resources Center is a typical super high-rise shear wall residential building.Its basement has a complicated relationship with surrounding structures.It′s a reinforced concrete out-of-code structure with a very irregular plane and a serious eccentric rigidity.First,the design of foundation and the selection of structural systems were introduced,and out-of-code conditions of the structure were analyzed to determine performance-based seismic design goals.Then,the structural elastic analysis under the action of frequent earthquakes and the dynamic elastic-plastic analysis under the action of rare earthquakes were carried out.According to the analysis results,the bearing capacity and deformation under different seismic levels were designed.Finally,the countermeasures of the key problems were discussed for the out-of-code problems such as height,torsional displacement ratio and height-width ratio.
