Plate or beam web
The general assumption is, that the joint plate is partially fixed by connected members. Therefore, joint plates are verified according to the rules for the class 3 (elastic analysis without local buckling consideration). This assumption has to be respected during the design of joint.
Shear
The design shear resistance is calculated using expression
Where is: | Av |
|
The holes are not considered if
Otherwise, the shear resistance is calculated using expression
Where is: | Av,net |
|
Beam web in shear
Beam web is verified with the help of the tearing effective length
using expression
Beam web subjected to shear
Plate in bending
The design bending resistance is calculated according to the chapter 6.2.5 of EN 1993-1-1 (class 3) using expression
Holes are considered if
Combination of shear and bending
If the shear force is smaller than the half of the design shear resistance, the combination of shear and bending is not considered in accordance with the chapter 6.2.8 of EN 1993-1-1. Otherwise, the combination of shear and bending is checked.
The joint plate in joints with angles can be subjected to complicated stresses. In these cases, only horizontal section along the weld is checked. This section is checked for the combination of tension, bending and shear. The sum of forces is checked for the joints with more connected members.
