SUMMARY OF BEAM-COLUMN CONNECTION ESIGN
7con connection8s allowable shear
Mcon connection8s allowable moment
7 ma4imum shear forces in connection 'from "#A output)
M ma4imum moment in connection from '"#A output)
Vcon > V , therefore connection design is adequate to resisting the external loads
Mcon > M , therefore connection design is adequate to resisting the external moment
