钢筋计算方式（Reinforcement calculation method） Hook length in the stirrups stirrup count how to calculate the value of the general experience of how satisfied answer: 1 flat drawing, the stirrup hook length LW is such a requirement: when the stirrup reinforcement, end hook is 135 degree earthquake: LW = max: (11.9d, 75+1.9d); general stirrup: LW = 6.9d., when the stirrup reinforcement end hooks for 180 degrees: Earthquake: LW = 13.25d; LW = 8.25d when ordinary stirrups, stirrup reinforcement end hooks for 90 degrees: Earthquake: LW = 10.5d; LW = 5.5d with ordinary stirrups: Answer 2: hook 90 degrees, the general structure of 5.5d; seismic architecture 10.5d, the hook is 135 degrees, the general structure of 6.87d; seismic architecture 11.87d, the hook is 180 degrees, 8.25d; seismic architecture for 13.25d. Single stirrup length = component section outside the perimeter -8* protective layer +4* + stirrup diameter increase the length of the hook The number of stirrups (= length of member - reinforced protective layer thickness) / stirrup spacing +1 The number of stirrup length = length * single stirrups stirrup Hanger length = 2* (20d) +2* cable anchorage length + width +2*50 beam, the frame beam height 800mm angle of =60 DEG to =45 DEG 800mm angle Cable length =1.414* (main beam high -2* protective layer thickness) Note: if the girder is too high, to special treatment Beam plate steel blanking length = beam axis size - the protective layer (25) + hook size 180 degree hook =6.25d 90 degree hook = 3.5D 45 degree hook = 4.9d Salty again to measure the difference: 30 degrees 0.3d, 45 degrees 0.5d, 60 degrees 1D, 90 degrees 2D and 135 degrees 3D If the construction drawings are generally according to the above method can be calculated as negative reinforcement distribution \ plate \ plate beam longitudinal stress reinforcement, tendons. If the frame is flat construction map that will reference 03G101-1B. Stirrup length: length + hook length -6d outsourcing Hook length 6 100\8 p
