RE: Roof Gardens Live load

[Subject Prev][Subject Next][Thread Prev][Thread Next]



If there are accessible areas the minimum live load is 100; but be really careful since even in an inaccessible area the landscaping weight can be much higher than 100 psf.  300 psf would be more likely.

Subject: Roof Gardens Live load


We do several jobs were we have live roofs (roofs with a gardens, not necessary accessible after construction).  Based on ASCE 7-05 table 4-1, the live load should be designed for 100 psf.  Can anyone clarify if this is only for roofs with gardens that is accessible. 


Any help would be great.
