Remarks

※Location parameter,Scale parameter and Estimated Annual Maximum Snow Depth for Gumbel Distribution are cited from 『Recommendations for Loads on Buildings(2004)』(Architectural Institute of Japan).
※1:It is a coefficient decided by "Roof slope angle" and "Mean Wind Speeds in January and February".It depends in the effect of snow blowing.
※2:It is a coefficient decided by "Roof slope angle","Mean Wind Speeds in January and February" and "Roof shape".This coefficient is applied for bottom of roof.
※3:It is a coefficient decided by "Roof slope angle" and "Roof shape".
※4:When the figure is not input to "Ambient Environment Confficient(kenv)", "kenv" is assumed to be "1.0" in the calculation.
※5:Return Period is set usually as 100year.
