moment due to vertical wind pressure for external floating roof

[inammanj123]

hi,

for external floating roof overturning moment from vertical wind pressure should be considered or not? I am designing a 92 m floating roof.iF I consider moment due to vertical pressure anchor are required, but that is practicle, so i think only moment due to horozontal wind pressure should be taken and moment due to vertical wind pressure should be kept zero.

regards,
Inam
