Roof live load reduction.
Where l r shall not be less than 12 psf and not more than 20 psf.
Likewise roof live loads in the hong kong building regulation can be reduced as a function of the slope.
R 1 1 for a t less than or equal to 200 psf r 1 1 2 0 001 a t for between 200 psf and 600 psf.
Use of live load reduction in accordance with section 1607 11 shall be indicated for each type of live load used in the design.
Roof live load may be reduced by the following equation.
1603 1 3 roof snow load data.
1603 1 2 roof live load the roof live load used in the design shall be indicated for roof areas section 1607 13.
Hence the magnitude of the roof live loads should be specified as for a flat roof and the program allowed to make the reduction based on the slope of the framing.
The live loads for members supporting two or more floors are permitted to be reduced by a maximum of 20 percent but the live load shall not be less than l as calculated in section 1607 10 1.
