MIDAS Information Technology Co., Ltd
(1) Bearing Stress
ㆍ fmax = 1.418N ( Area = 1.000mm² )
ㆍ fmin = 1.418N ( Area = 1.000mm² )
ㆍ σmax = 1.418MPa
ㆍ σmin = 1.418MPa
(2) Calculate Bearing Stress of Concrete
ㆍ Φ = 0.650
ㆍ A1 = 229,600mm², A2 = 270,000mm²
ㆍ Fn = 0.85 fck
A2 / A1 = 32.26MPa
ㆍ øFn = 20.97MPa
(3) Calculate ratio
ㆍ σmax / øFn = 0.068 < 1.000 → O.K

(3) Design Moment ( Use Average )
ㆍ Mux = -12.80kN·m/m
ㆍ Muy = -9.374kN·m/m
ㆍ Mu = max( Mux , Muy ) = -12.80kN·m/m
(4) Calculate moment strength
ㆍ Φ = 0.900
ㆍ Zbp = ( tbp ) 2 / 4 = 144 mm 3 /mm
ㆍ Mn = Fy x Zbp = 39.60kN·m/m
ㆍ øMn = 35.64kN·m/m
(5) Calculate ratio

ㆍ Mu / øMn = 0.359 < 1.000 → O.K
8. Check anchor bolt ( Cast-In-Place )
(1) Design Force
ㆍ Number of Anchor Bolt = 6EA
ㆍ Tu.max = 0.000kN
ㆍ Vu = 22.95kN
ㆍ Vu1 = 3.824kN
(2) Check Shear Strength
ㆍ Φ = 0.750
ㆍ Ab = 452mm²
ㆍ Fnv = 320MPa
ㆍ Rnv = Fnv x Ab = 145kN
ㆍ øRnv = 109kN
ㆍ Vu1 / øRnv = 0.035 < 1.000 → O.K
9. Check Development Length of Anchor Bolt
ㆍ Tension Force is not Exist.
