Cs for a 30-foot ramp and 5x10 platform of 0.5 and a design wind load of 30 psf without <br /> consideration for stress duration. Seismic and wind loads do not govern lateral loading for <br /> standard configurations. Standard platform lateral loading will be resisted by connections of <br /> platform to building. (3) SDS25300(OR 3/8"O x 3" lag-bolts=900#for each 5' platform section. <br /> Lateral loads of ramps and stair assemblies attached to the platforms will be resisted by the <br /> platforms. <br /> f) Anchorage for Asphalt and Concrete Substrate: Where requested by the Owner,anchorage of <br /> ramps and stairs to asphalt and concrete substrates will be done with drilled anchors.Asphalt <br /> substrate conditions will use (1) 'Bolt-Hold'SP-10 at each bottom bearing plate of last section of <br /> ramp and bottom of stair. Concrete substrate conditions will use (1) 'Simpson'Titen HD <br /> %"0x3". <br /> WELCOME RAMP CALCS-IBC 2018 Page 3 <br />
