The purpose of this study is to compare how different bracing systems behave in steel structures. The analyses were conducted to assess the structural performance of different bracing configurations in a 75-m-tall steel tower building. In tall building structures, stiffness is often more critical than strength. Stiffness is frequently more important than strength in tall building constructions. In steel constructions, braced and moment-resisting frames are frequently utilised as lateral load-resisting components. Braces, which link concentrically to the beam-column joints, can be used in a variety of configurations to increase the resistance of such structures. These configurations include the standard diagonal bracing, X-bracing, K-bracing, and V-bracing. This project utilises STAAD PRO to model and analyse the 75-m-tall tower, measured from the finished floor level (FFL), and incorporates mezzanine floors at various levels. Bracing is strategically applied to improve the structure's stability under different load conditions. The analysis evaluates deflection and strength criteria to ensure the design meets structural integrity requirements by comparing the performance of the different bracing systems.

摘要

The purpose of this study is to compare how different bracing systems behave in steel structures. The analyses were conducted to assess the structural performance of different bracing configurations in a 75-m-tall steel tower building. In tall building structures, stiffness is often more critical than strength. Stiffness is frequently more important than strength in tall building constructions. In steel constructions, braced and moment-resisting frames are frequently utilised as lateral load-resisting components. Braces, which link concentrically to the beam-column joints, can be used in a variety of configurations to increase the resistance of such structures. These configurations include the standard diagonal bracing, X-bracing, K-bracing, and V-bracing. This project utilises STAAD PRO to model and analyse the 75-m-tall tower, measured from the finished floor level (FFL), and incorporates mezzanine floors at various levels. Bracing is strategically applied to improve the structure's stability under different load conditions. The analysis evaluates deflection and strength criteria to ensure the design meets structural integrity requirements by comparing the performance of the different bracing systems.
