Long cleat connection VRd : design shear resistance for the connection element

See Ref.[30].

When only 1 bolt is present at each cleat in the column web, the shear stress is adapted as follows :

The normal stress remains valid as follows :

with

A                            

h t n

W

n t h² / 6

N

the present normal force

M

the present moment : VRd a

a

 

σN

the normal stress generated by normal force N

σM

the normal stress generated by moment M

τ

the shear stress

n

the number of plates

eu

see figure

In the limit state, we allow the following :

with

fy

the yield strength of the element

γM0

the partial safety factor

 

The design shear resistance VRd is the solution of the following equation :
