Numerical Study of Wind Loads on Y Plan-Shaped Tall Building Using CFD

The increase in the population is at an exponential rate, and available land form of irregular shapes. That why shapes are very commonly built. Wind load increases with respect to height, so wind evolution necessary for such high-rise structures. forces majorly depend on plan's cross-sectional shape. Therefore, shape, investigation needed tall buildings. This paper demonstrates a detailed study velocity stream line, external pressure coefficients, distribution surfaces building turbulence kinetic energy Y-shaped plan buildings under excitation incidence angles 0o 180o. k- model utilized solve problem using computational fluid dynamics techniques ANSYS terrain category II as per IS: 875 (Part3), 2015. ward faces all models show positive distribution, while leeward effect negative distribution. can be reduced by modifying corners, chamfering, rounding, double recessed. variation different "Y" shaped 0° 180° investigated CFX, contours plotted compute corner modification In this research, it was found that rounded corners highly efficient resisting load.
