［摘要］青島環(huán)球金融中心3#塔樓屋面高度164.5m，為超B級高度超高層結(jié)構(gòu)，塔樓平面形狀呈Z字形，屬于角部重疊的平面不規(guī)則類型。塔樓底層局部兩片剪力墻不落地，采用局部轉(zhuǎn)換。通過合理選取結(jié)構(gòu)布置、加大薄弱部位樓板厚度，使角部重疊區(qū)的結(jié)構(gòu)抗震性能達(dá)到最優(yōu)。設(shè)計(jì)中采用延性較好的型鋼結(jié)構(gòu)，通過提高底層轉(zhuǎn)換構(gòu)件的性能目標(biāo)，使連梁在罕遇地震作用下充分發(fā)揮了耗能作用，主要結(jié)構(gòu)構(gòu)件均未發(fā)生塑性損傷。

Abstract:The roof height of Tower 3 of Qingdao World Financial Center is 164.5m, which exceeds B-grade height requirement of the code. The plane shape of the tower is Z-shaped, which belongs to the irregular type with overlapping corners. Two shear walls at the bottom floor of the tower are not landed, and adopt local conversion. By selecting a reasonable structural layout and increasing the thickness of the weak part, the seismic performance of the structure in the corner of the overlap area can reach the optimal. The center adopts the steel structure with the better ductility in the design. By improving the performance target of the bottom conversion components, the coupling beam could fully play a role of energy dissipation under the rare earthquake action, and the main structural components does not have the plastic damage.
Keywords:Qingdao World Financial Center; Z-shaped plane; irregular corner overlap; structural height exceeding B-grade height requirement of the code; performance-based seismic design
