Seismic response of post-tension shear walls – Outrigger structure

This research was conducted by combining two structural systems: post-tensioned core walls and an outrigger in a 40-story building. A Vierendeel system applied to one stories, comparison between models performed determine the best locations. In addition, effect of at only 25 % building height investigated. Subsequently, positions were with bonded post-tension %. The results showed improvement lateral stiffness using outrigger, roof displacement enhanced approximately 42 14 Both systems worked together reduce 50
