Abstract
The purpose of this study is to predict the ratios of increase in lateral stiffness for preliminary structural design of tall buildings. For this, the basic models of tall buildings with 60 stories are generated. The basic models have typical floor plan of Box or T type. And the factors for increase in lateral stiffness are selected as follows; the addition of outriggers, increase in material strength, and increase in member size of core walls, outrigger columns, and outrigger walls. Then these factors are applied to the basic models and their effects are investigated using the results of structural analysis. Finally, based on the investigation, the ratios of increase in lateral stiffness for preliminary structural design of tall buildings are proposed and applied to examples of tall building for verification of the ratios.
