Abstract: The key design highlights of the super high?rise structures in Suzhou Honghai International Plaza were elaboratedand analyzed. In view of the irregularity of the " I" ?shaped plane of the project, a layout scheme was proposed. Tworeinforced concrete cylinders are set up at the intersection of the " flange" and " web" of the I?shaped plane,shear wallswere arranged on both sides of the recess to connect with the concrete cylinder. SATWE and MIDAS Building software wereused to conduct overall analysis of the structural, and PKPM?SAUSAGE software was used to conduct elasto?plastic timehistory analysis. The results show that the structural layout is reasonable and the overall seismic performance is good. Theseismic performance indicators were formulated for the weak seismic parts and key components. The shear bearing capacityof the shear wall and frame column at the bottom reinforced part is controlled according to the middle earthquake elasticity,and the eccentric compression bearing capacity is designed according to the middle earthquake non?yielding design. Thefloor slabs connecting the weak parts and vertically retracting the floors were designed according to the mid?seismicelasticity. For the wall whose nominal tensile stress is greater than the standard value of concrete tensile strength under theaction of fortification intensity earthquake, the section steel was set to bear all the tensile force to ensure the safety of thestructure.
Keywords:super high?rise structure; performance?based design; dynamic elasto?plastic time history analysis
