Description

Design wind Wind loading on low building has been an area of active investigation due to increasing public concern towards severe damage caused by windstorms in recent years. loading is mainly obtained from different codes, wherein the major source of information on which specifications are based is wind tunnel testing of scaled rigid models under simulated flow. Recent studies on full-scale/model-scale comparisons have brought out issues of flow simulations and measurement techniques with greater clarity, thus enabling improvements in existing information.Modeling of extreme value distribution has been used for deduction of design pressure coefficient. This is based upon generalized (3 parameter) Gumbel method. For this technique L-moment (Hosking 1990) has been used. Further design pressure coefficients for different zones of the building using extreme value distribution with central moments.
