摘要：青岛蓝色中心酒店项目存在扭转不规则、凹凸不规则、楼板不连续、局部穿层柱等不规则项，属于超限高层建筑。结构设计过程中，进行了小震弹性分析和大震动力弹塑性分析，针对结构的薄弱部位采取了一系列有效的加强措施。采用基于性能的设计方法进行结构抗震设计，可以实现预期的D级抗震性能目标。同时还对网壳屋盖与主体结构的连接方案进行了分析比较，采用了弹性支座的弱连接方式，减小了网壳的跨中挠度，并且使水平推力相对较“均匀”地传递给下部结构。对超长结构楼盖进行了温度应力分析，对温度应力较大部位的楼板进行了加厚处理，并根据温度应力计算结果对楼板配筋进行了加强。

Abstract: Qingdao Blue Center Hotel project with irregular items such as torsional irregularity, concave and convex irregularity, floor discontinuity, partial crossing column and so on, belongs to the out-of-code high-rise building. In the process of structural design, the elastic analysis of small earthquakes and the dynamic elasto-plastic analysis of large earthquakes were carried out. A series of effective measures were taken to strengthen the weak parts of the structure. The performance-based design method was adopted for structural seismic design, which can achieve the expected D-class seismic performance target. At the same time, the connection scheme between the reticulated shell roof and the main structure was analyzed and compared. The weak connection mode of elastic support was adopted, which reduces the mid-span deflection of the reticulated shell and makes the horizontal thrust transfer to the substructure relatively evenly. The temperature stress analysis was carried out on the super long structure floor, and the slabs in the parts with high temperature stress were thickened, and the reinforcements of the slabs were reinforced according to the results of temperature stress calculation.

Keywords: out-of-code high-rise building; dynamic elasto-plastic analysis; temperature stress analysis; mode of connection between reticulated shell and main structure; performance-based seismic design
