Plant on roof dead load.

Note that the use of soil load h in the asce load combinations was intended to cover lateral earth pressures. Dead load of attic floor when floored 20 lbs. The dead load of a green roof assembly should be determined on a project specific basis because growth medium composition varies from job to job. Live load on attic floor local requirements.

3 3 dead loads dead loads consist of the permanent construction material loads comprising the roof floor wall and foundation systems including claddings finishes and fixed equipment. When used for storage only dead load of attic floor not floored 10 lbs. The last most common unknown is designing for tree vertical and lateral loads. Thus two conservative assumptions could lead to over.

Where uniform roof live loads are reduced to less than 20 psf 0 96 kn m 2 in accordance with section 1607 13 2 1 and are applied to the design of structural members arranged so as to create continuity the reduced roof live load shall be applied to adjacent spans or to alternate spans whichever produces the most unfavorable load effect see section 1607 13 2 for reductions in minimum roof. The venny green roof has shallow substrates on two types of roof the first roof is on shipping containers and is designed for a dead load of 250kg m 2 and live load of 100kg m 2. Overturning should also consider roof uplift forces unless a separate load path is designed to transfer those forces. The second trussed roof is designed for a dead load of 160kg m 2 and a live load of 40kg m 2.
