Question:zhangsheng
ircle circular failure surface of resist torque W= x (3R2 +3R 2+ 3).
Type on, r is the ring inner diameter, is the ring width.
W= x failure surface resistance moment (3R2 +3R 2+ 3) = Pi x (3x842x4+3x84x42+43) =88768mm3=88.768x10-6m3
Wind load on failure surface in moments of stress caused by =M/W=1466/(88.768x10-6) =16.5x106pA=16.5MpA 215MpA
Where 215MpA is the bending strength of steel Q235.
Therefore, design of weld width selected to meet the requirements
