Analysis of Framed-Tube, Braced-Tube, and Outrigger System in Tall Buildings
摘要
Since the early twentieth century, tall building design has evolved with a focus on realism, material efficiency, and constructability, allowing for taller structures. Advances in materials, software, and structural systems have driven this progress, emphasizing a balance between architectural expression, safety, serviceability, and efficiency. Current trends favor composite structures to handle lateral loads like wind and earthquakes. This study analyzes framed-tube, braced-tube, and outrigger systems for 60-story buildings situated within Seismic Zone III, characterized by medium soil using dynamic analysis with response spectrum method and gust factor for wind load calculations.
