Structural design of Linyi Jinshuiwan Phase Ⅱ super high-rise building
Linyi Jinshuiwan Phase Ⅱ super high-rise project has a structural height of 153.3m,belongs to the super high-rise out-of-code structure in the high-earthquake area.The above-ground adopts a concrete filled steel tube frame-reinforced concrete core tube mixed structure.The perimeter frame columns were inclined gradually to meet the profile of the building's façade.Two softwares,YJK and ETABS were used for elastic analysis of the main tower structure,and PERFORM-3D software was used for dynamic elastic-plastic analysis.The design of super high-rise structure was briefly discussed from the aspects of structure system and performance design.The main points of inclined column design,ring truss,bottom forked column and structural dynamic elastic-plastic aspects of shuttle-shaped super high-rise building were analyzed and introduced in detail.Finally,the calculation conclusion of the above points and construction suggestions were given.
