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