Does effect of local wind pressure coefficient (IS 875 Part -3) to be applied to Rafter members of a roof structure but not on column and foundation.

I am unable to understand the use of local coefficient.

Thanks.

Dear Chandrakant,

The local pressure coefficients are meant to be used for designing local cladding systems (glass panels, aluminium panels etc) which are smaller in size.

Dear Sir,
the local coefficient values are generally  more than the global coeffieincts. these are genrally adopted for fastenings and claddings where high vulnerability of wind pressures are occured.
