Abstract
Recent decades have witnessed a significant development in the construction engineering sciences and structural systems to keep pace with the competitive race of the world’s countries to reach the sky. Many countries worldwide aim to build skyscrapers or unique structures to attract investments and improve their economic situation. This study is concerned with one of the most common and effective lateral resisting systems, the outrigger system. The outrigger system is used in numerous tall and super-tall buildings. It consists of reinforced concrete walls or steel trusses that connect the core to the perimeter columns at one or more levels. When lateral loads are applied to the structure, the core rotates, causing stresses on the outrigger trusses to generate tension in the windward columns and compression in the leeward columns. This coupling force generates a restoring moment that acts on the core at the outriggers’ level. In recent years, there have been many studies on improving the performance of the outrigger system by combining it with seismic energy dissipative devices.
