Dear Subramaniam sir,
Usually we are calculating pressure for 0 deg and 90 deg case for wall. Whereas 45 deg case be the critical case bcoz, we are applying pressure simultaneously 0 deg and 90 case in one combination. Initially I have calculated projected length as per SP64:2001. Then, I have tried to calculate the  total force as per cl.6.2.1 equation in IS 875 Part 3 :1987.But I find it difficult to calculate bcoz we don't have external pressure coefficient for wall at 45 deg case. The equation has been derived only normal to individual structural element or cladding unit. Herewith I have enclosed the calculation which I have done. Kindly do the needful

Yours Sincerely
P.SABARINATHAN
