| 摘 要： | 国家游泳中心“水立方”现浇钢筋混凝土斜看台楼盖跨越两个结构层,形成一个连续、复杂的空间结构。现浇斜看台楼盖建筑尺度及刚度较大,其对整体建筑结构工作性能尤其对地震作用下各类结构构件受力影响较大,不容忽视。我国《建筑抗震设计规范》(GB 50011—2001)对此类带现浇斜楼盖结构抗震设计尚没有明确的规定。本文结合国家游泳中心“水立方”斜看台楼盖结构设计,通过对带现浇斜看台楼盖和不带现浇斜看台楼盖两类结构在水平地震作用下的计算分析,揭示了现浇斜楼盖对整体结构工作性能及对各类结构构件地震作用下受力的影响规律,提出了此类结构的抗震设计建议。

| Abstract: | The cast-in-situ RC slope floor structure of the stands of National Swimming Center "Water Club" spanned two stories and formed a continuous and complicated spatial structure.The significant influence of cast-in-situ RC roof on the dynamical characteristics of the structure and member forces under earthquake action must not be neglected because of its large size and stiffness.There are no related specifications for aseismic design of this kind of structure in GB 50011—2001 "Code for Seismic Design of Bulidings".Based on the analyses of structures with and without cast-in-situ RC slope floor,this paper reveals the significant influence of slope floor on the dynamical characteristics of the structure and member forces under earthquake action.Finally,the related proposals for aseismic design of this kind of structure are presented. |
