Part 5: Joint Design 5 – 29 3.2.5.3 Shear and bending interaction for un-notched beam B B C C D D A A e e 1 V Ed 2 V Ed p 2,b 2,b p 2 z z Ed z ( -1) 1 n ( + ) z p V V Ed p p p p z = z For short fin plates (i.e. z ≤ t p /0,15) the resistance of the web does not need to be checked [4 ] . For long fin plates (i.e. z > t p /0,15) it is necessary to ensure that the section labelled as ABCD in the figure can resist a moment V Ed z p for a single line of bolts or V Ed ( z p + p 2 ) for a double line of bolts (AB and CD are in shear and BC is in bending). Basic requirement: For a single vertical line of bolts (n 2 = 1) V Ed z p  M c,BC,Rd + F pl,AB,Rd ( n 1 – 1) p 1 [Reference 4] For two vertical lines of bolts (n 2 = 2) V Ed ( z p + p 2 /2)  M c,BC,Rd + F pl,AB,Rd ( n 1 – 1) p 1 [Reference 4] M c,BC,Rd is the moment resistance of the beam web BC For low shear (i.e. V BC,Ed ≤ 0,5 F pl,BC,Rd ) M c,BC,Rd =     2 1 1 M0 y,b w 1 6 n p f t   For high shear (i.e. V BC,Ed > 0,5 F pl,BC,Rd ) M c,BC,Rd =     2 1 1 M0 y,b w 1 4 n p f t                     2 Rd,min Ed 1 1 2 V V F pl,AB,Rd is the shear resistance of the beam web AB F pl,BC,Rd is the shear resistance of the beam web BC where: For a single vertical line of bolts ( n 2 = 1): F pl,AB,Rd =          M2 0 w u,b 2,b M0 2,b w y,b 3 2 ; 3 min   t f e t f e d
