Research Projects

Rare or extreme events (EE) are infrequent but widespread events that can destabilize systems, such as stock markets, ocean wave intensity, major earthquakes, hurricanes, and floods. Understanding EE in engineering systems is crucial due to its real-life applications, such as power grids, mechanical part failure, and building structure collapse due to heavy external fluctuations. Optimized building designs are essential to withstand diverse natural hazards and protect people from such dangers. The development of structural engineering has improved our ability to understand and capture the effects of turbulent wind flows. The statistical distribution of wind loads on buildings has evolved from Gaussian to non-Gaussian distributions due to specific critical situations. Recent studies have shown that the distribution is not only non-Gaussian but also has potential for EE with a peak factor seven times more prominent than the standard deviation. Preliminary works suggest the possibility of extreme vibrational events in building structures, which require immediate attention. The project aims to design models of medium and high-rise buildings and understand extreme wind load characteristics at different terrains based on Is875 (part 3) wind loads. The results will help investigate the mechanism of partial or complete collapse of buildings and the possibility of damages at certain parts of the buildings. Pressure sensors will be equally distributed to estimate the degree of extremeness due to various wind flow, and the effect of turbulence intensity on extreme surface pressure characteristics will be studied.
