## 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
