Abstract:
Urbanization has seen the rapid increase in tall buildings, and thus to ensure the tall buildings in the future with efficient structural systems to support the lateral loads caused by winds and seismic activities. Bracing systems and belt wall systems have become one of the most effective approaches of improving the stiffness, stability and the overall performance of high-rise buildings among other lateral load-resisting mechanisms. The paper gives a critical analysis of the integrated bracing and belt wall systems with reference to the combined effect on the structural behavior behavior of tall buildings during wind and earthquake load conditions. The paper critically examines various bracing configurations such as concentric, eccentric, and diagrid bracing systems, as well as belt wall systems and how these interact with core and outrigger systems. The lateral displacement, inter-story drift, base shear, stiffness and energy dissipation capacity are considered as key performance parameters regarding the results of recent experimental, analytical and numerical investigations. The review notes that the combination of bracing systems with belt walls considerably enhances redistribution of the load, minimizes structural load to primary members, and improves the overall resilience of the building. More so, the effects of building height, geometry, irregularity, and the inclusion of dampers on effectiveness of the system are critically discussed. The paper establishes research gaps in the literature, especially on optimization of hybrid systems, their performance in multi-hazard conditions, and using advanced computational and machine learning methods. The conclusions of this review are helpful to researchers and working engineers when designing and optimizing the high-performance tall building systems.
