Abstract
Shear wall system with outrigger, most popular structural system for controlling lateral displacement of tall buildings, is core wall, outriggers, external walls, internal walls, and partition walls called structural elements. The studies on the capacities of outrigger and core wall have been advanced. However structural elements except for that have no practical and economic guidelines for adequate design to resist lateral loads. On this account, it is necessary to investigate the effects of interaction of each wall element to lateral displacement. In this study, thickness of structural wall as well as core wall, outrigger, interaction of each wall, and design strength are used as design variables. Analysis of example structures which are a plane figure on Y type and 60 stories shear wall-outrigger system were performed and compared top drift along design variables. As results, structural elements are effective factors to control lateral displacement and core wall-external wall integration is optimum system.
