| Abstract |
This study aims to find a reinforcement method of floor slabs to improve lateral stiffness of offset outrigger systems in high-rise buildings.
A structure analysis and design of 70-story buildings utilizing the MIDAS-Gen program were analyzed. The key variables observed were the
reinforcement method of floor slabs between shear wall and offset outrigger, the plate thickness of H beam and slab thickness. Based on
these results, the lateral displacement reduction ratio and the structural efficiency of the methods reinforcing floor slabs, the axial force in
diagonal members of outrigger systems and the maximum principal force distribution of slabs between the shear wall and offset outrigger
were analyzed. The research results revealed that the reinforcement method of floor slabs had an impact on the lateral stiffness of the offset
outrigger system in tall buildings. These results could be quite valuable in further obtaining important engineering data for the structure
design of high-rise offset outrigger systems. |
