Lateral Stiffness Optimization in Structural Scheme Design of a Super High-Rise Building in 0.30g Seismic Fortified Regions

Abstract:

It was optimized that the lateral stiffness of an under-designed super high-rise building located in 0.30g seismic fortified regions, with 58 stories above the ground and 235.80 meters total structural height. By having adequately adjusted the wall thicknesses of the core-wall and the cross sectional dimensions of the frame columns, a more reasonable structural scheme was obtained. It was then discussed the suitable numbers and heights of the strengthening stories set for controlling the building’s story drifts. Finally, it was explored that the efficiency of seismic input energy dissipation via viscous dampers installed at the right places of the structure.
