Aprox 40'x60' platform with industrial grating over WF beams over 4 HSS columns. About 16' tall. Purpose: to provide some protection to the existing small pump station below from falling ice from an adjacent tower.
My question is about the lateral force I need to design this new structure for. Self weight is not that much, and seismic design category is B so seismic loads are low. Is there something in the code or good rule of thumb for a minimum lateral load I should design for. I was thinking about 10% of live load/snow over the platform.
