摘　　要：某超高层建筑塔楼的两侧子结构通过每层的两条连廊连接,形成平面细腰型且开洞的结构形式。通过1∶35缩尺比例模型的振动台试验,研究了模型的破坏形态、动力特性、加速度响应、位移响应、扭转响应等,重点研究了连廊的应变响应。结果表明:在采用规范方法所选地震波作用下,模型未见破坏;在速度脉冲型地震波作用下,多层连廊端部产生竖向裂缝。模型以Y向整体侧移为主,两侧子结构发生明显的异步变形,对连廊受力不利。建议在设计时,除了加强连廊与子结构的连接外,应尽量减小子结构抗侧刚度的差异,控制细腰部分的缩进程度和开洞尺寸,控制子结构外伸段长宽比以及两侧外伸段的抗侧刚度差异。The substructures on both sides of a super high-rise building tower are connected by two corridors on each floor.The plane of the structure is narrow-waist and has an opening.Through the shaking table test of the 1∶35 scale model,the failure mode,dynamic characteristics,acceleration response,displacement response and torsion response of the model were studied,and the strain response of the corridor was mainly studied.The results show that under action of seismic waves selected by the method in code,there is no damage to the model.Under action of velocity pulse seismic waves,vertical cracks are produced at the end of the corridors in several stories.The model is dominated by the overall lateral displacement in the Y direction,and the substructures on both sides have obvious asynchronous deformation,which is unfavorable to the stress of the corridor.It is suggested that in the design,in addition to strengthening the connection between the corridors and the substructures,the difference in lateral stiffness of the substructures should be reduced as far as possible.The indentation degree and hole size of the narrow-waist area should be controlled.The aspect ratios of the extension areas of the substructures should also be controlled,as well as the difference of lateral stiffness in both extension areas of substructures.
