Description |
A wind tunnel study on pressure measurements on a 1:200 scale model of a coal shed with
open gable end walls has been carried out. The model has been instrumented with pressure
taps over the roof surface. Dynamic pressures have been measured for different angles of
wind incidence ranging from θ = 0˚ to 360˚ in steps of 30˚ intervals. All the data have been
collected for a reference mean velocity of 12 m/s at the crown of the model. Results on mean
and standard deviation of external and internal pressure coefficients are presented and
discussed for the three important angles of wind incidence, i.e., flow parallel to the axis of the arch (θ = 0°), diagonal (θ = 315°) and normal (θ = 270°), which are more important from
design point of view. A procedure has been suggested for suitable combination of mean and
fluctuating external and internal pressure coefficients to compute the peak load effects.
