Abstract: Qingdao Lushang Center Project in district 1C adopts reinforced concrete frame-core structure system with the structural height of 247.5m, which is an ultra-B-level and super high-rise building. Based on the engineering characteristics of the tower and the over-limit situation, different softwares were used to calculate and analyze the structure under the action of frequent earthquakes, fortification earthquakes and rare earthquakes. The foundation design on the rock foundation of the tower was introduced, and finally, a special analysis was carried out for wind load and construction simulation. The results show that the seismic performance objective of “three levels” can be achieved.
Keywords:Qingdao Lushang Center；super high-rise building； foundation design； performance-based seismic design； elastic-plastic time history analysis； shrink and creep effect； construction simulation
