Stiffened end plate (27)

Stiffened end plate (27) connects two beams, or a beam to a column, using an end plate at the secondary beam end and a T-shaped plate construction consisting of a stiffener and a shear tab. The plates are connected with bolts.

Dimensions

Description

1

Front plate edge distance from the main part flange.

2

End plate edge distance from the secondary part flange.

3

Gap between the front plate and the shim plate.

4

Shear tab edge distance from the main part flange.

This dimension has an effect on the shear tab size.

The lower box is for controlling the shear tab on the other side of the main part.

5

Shear tab edge distance from the main part web.

The lower box is for controlling the shear tab on the other side of the main part.

6

Stiffener edge distance from the shear tab edge.

7

Shear tab edge distance from the main part flange.

This dimension has an effect on the shear tab size.

8

Front plate edge distance from the main part flange.

Gap size

Define the limit value for the gap between the end plate and the secondary beam. Use this when the beam is slightly curved or sloped to decide if the end angle is so small that the beam end can be straight.

If the actual gap is smaller than this value, the end of the beam is left straight.

If the actual gap is larger than this value, the end of the beam is fitted to the end plate.

Parts tab

Use the Parts tab to define the part properties.
