Remarks

・Rate of Reduction:r(%)
r=0.08:『Flat or rise less than 4 units vertical in 12 units horizontal (33.3% slope). Arch or dome with rise less than one eighth of span.』(Reference[1])
r=0.06:『Rise 4 units vertical to less than 12 units vertical in 12 units horizontal (33% to less than 100% slope). Arch or dome with rise one eighth of span to less than three eighths of span.』(Reference[1])
・Type of Member:
:Receiving load from one level only such as horizontal member
:Other member such as vertical members
