Abstract
ABSTRACT: These types of torsional irregularities of high-rise buildings tend to have a major impact on how a building is affected with wind forces and may put the safety and function of the structure at risk. In this case, the focus is on the high-rise buildings with different kinds of torsional irregularities, which is now dissected concerning its behavior and the performance under wind loads. The analysis includes the computation of buildings with different mass, stiffness, geometric factors and their torsional response together with the wind load resistance factors. State-of-the-art methods of computational modeling and simulations are used to estimate displacements and rotations as well as the stress concentration and distribution. Parameters such as the torsional amplification factor or the dynamic response characteristics analyses are used where a dependency on the type and degree of irregularity is observed. The reveal of a high relevance of the torsional irregularities was demonstrated differently, for some configurations of the building irregularities increases the torsional effects and thus stress concentrations together with lateral displacements. Furthermore, design recommendations are given on how to minimize these unwanted torsional effects including the recommendations for the inspired symmetry of structure, optimal strength, and increased damping abilities. This work provides insights into the design and evaluation of high-rise structures to ensure their safety and resilience against wind loads, contributing to the development of improved design codes and practices for torsionally irregular buildings.
