Pyramid type str :
Since pyramid str cladding is wall as well as roof
External pr coeffs -  Higher  effects to be taken by working out from - - table 5 values on projected vertical area and Table 6 values on projected plan atea  ,,  I think  .

Hope some other members may further clarify.



Internal pr coff - ( + & - )O. 2p /O.5p /O.7pas per opening%

As it is a open structure with no wall and cladding
I internal press. Coefficient. +/-0.7  , I used
Thanks for guiding me on ext. Pressure coefficient.
