Evaluation of aerodynamic force coefficients on tall buildings
Estimation of peak pressure coefficient for cladding design
Studies on tall buildings have been carried out for M/s Sane Associates, M/s Raheja Universal Pvt. Ltd, M/s Jaiprakash Associates, M/s ONGC Ltd, M/s Maharashtra Housing and Area Development Authority (MHADA), etc
Wind Tunnel Investigations on Tall Rectangular Building Models
Most of the national/international codes on wind loads provide mean drag coefficient values for tall rectangular buildings in the form of uniform pressure/force coefficients.
Full-scale Investigations on Free Standing and Guyed Lattice Towers
Lattice steel towers are used for a number of diverse purposes, namely, telecommunications, radio and television broadcasting, observation, power transmission and lighting supports, etc. The need to design a lattice tower for resonant dynamic response due to wind load arises when the natural vibration frequency (fundamental frequency) of the structure is low enough to be excited by the turbulence in the natural wind.
Wind Tunnel Investigations on Curved Roof Structure Models
Systematic investigations using pressure measurements have been carried out on a curved roof structure model with different wall-height to span ratios, accounting for the effect of angles of wind incidence and terrain condition. These aspects are not covered in IS 875 (Part 3) -1987, which provides the pressure coefficients under uniform flow condition.
2-D CFD Investigations on Bluff-body and Bridge Deck Sections
A series of 2-D CFD investigations have been carried out on various geometries, viz. square, rectangular, circular, triangular, L-angle, 4 L-angles, H-section, Trapezoid, curved roofs, etc. to evaluate aerodynamic pressure coefficients and drag & lift force coefficients. These evaluated coefficients have been compared with experimental results to validate the performance of different turbulence models using commercially available software (FLUENT 6.3).
