无锡深港国际A1地块甲A写字楼为钢筋混凝土框架-核心筒结构。本工程高层塔楼部分存在楼板不连续、大悬挑、扭转不规则、刚度突变等多项不规则类型。针对工程的上述特点,重点探讨了结构布置、抗震性能设计目标、竖向地震作用、施工过程模拟等问题。通过静力弹塑性分析找出结构的薄弱部位,并采取有针对性的抗震加强措施来实现结构的抗震性能目标,为类似工程提供借鉴。
Wuxi Shenzhen Hong Kong International A1 block A office building is a reinforced concrete frame - the core tube structure. There are many irregular types in the high-rise tower of the project, such as discontinuous slabs, large cantilevered, irregular torsion and sudden change in stiffness. According to the above characteristics of the project, the problems of structural arrangement, seismic design goals, vertical seismic action and construction process simulation are discussed. Through the static elasto-plastic analysis to find the weak parts of the structure, and take targeted seismic strengthening measures to achieve the seismic performance of the structure of the target for similar projects to provide reference.
