Advance Design Steel Connection offers a wide variety of steel joints that can be calculated according to the EC3 norm, in a fast way, efficiently covering many of the situations that can occur in the steel joint calculation.

The joint library from Advance Design Steel Calculations is divided into 4 categories according to the connection type or the connected elements structural function.

I. The first category is Beam to Beam and it contains the following joints:

II. The second category is Beam to Column and contains:

III. The third category is Base Plate and contains:

IV. The fourth category is Bracings, and contains:

In the following section, each category is detailed and for each joint, a specific example is provided

I. Beam to Beam category

I.1. "Apex Single Haunch" - usually this connection is used for roof beams. (Fig. 1).

I.2. "Clip Angle" - Usually this joint is between a primary beam and a secondary beam. The connection between the two beams is made through one or two angles.
"Clip Angle" joint is used when the secondary beam is perpendicular to the main beam.

I.3. "Clip Angle Skewed" - This joint is similar to the second one, the difference being that the secondary beam is not necessarily perpendicular to the main beam. In this joint the connection between the two beams is not made through bolted angles, it is made through angled plates. The secondary beam can be in the main beam's plane (Fig.3), or not (Fig. 4).

I.4. "Double Side Clip Angle" - This joint is created between a main beam and two perpendicular secondary beams on opposite sides. The connection between the beams is made through bolted angles. Both secondary beams are connected to the main beam by the same bolts.

I.5. "Moment End Plate" - This joint is made by welding a steel plate perpendicular to the secondary beam end that is bolted on the main beam flange or web (Fig.6).

Fig. 6 Moment End Plate joint from the Beam to Beam category

I.6. "Shear Plate" - This joint is made by a steel plate welded perpendicular to the main beam web and bolted along the secondary beam web.

I.7. "Single Side End Plate" - This joint is very similar to the "Moment end Plate", the big difference between the two joints is that the "Single Side End Plate" is not able to handle the bending moment from the secondary beam. This joint is calculated like an articulation.

II. The second category is "Beam to Column"

II.1. "Clip Angle" - Just like in the case of the second joint from the first category, the beam is connected to the column by angles (Fig. 10)

Fig. 9 Clip Angle joint from the Beam to Column category

II.2. "Clip Angle Skewed" - The second joint from this category is similar to the first one, the only difference being that this one does not require the perpendicularity between the connected elements.

II.3. "Double Side Clip Angle" - This connection is similar to the one with the same name from the first category, only with this one the beams are connected to the column, and not to the main beam (Fig. 11).

II.4. "Knee of Frame, with haunch" - In this joint the beam has a welded haunch and an end plate bolted to the column (Fig. 12).

II.5. "Moment End Plate" - This joint is very similar to the fourth one except the connected beam does not have the welded haunch.

II.6. "Shear plate" - This joint is identical to the similar one from the first category, the only difference being the support element; in this case the support element is a column (Fig. 13).

Fig. 14 Shear Plate joint from the Beam to Column category

II.7. "Single Side End plate" - This joint is very similar to the "Moment end Plate", the big difference between the two joints is that the "Single Side End Plate" is not able to handle the bending moment from the secondary beam. This joint is calculated like an articulation.

III. The third category is "Base Plates"

III.1. "Base Plate" - This joint is created by welding a steel plate to the bottom end of the column that is connected to the foundations through bolts or anchors. The joint can include several reinforcement plates, shim plate or shear anchor.

III.2. "Base Plate Cut" - For this connection the bottom end of the column must be adjusted (Fig.17).

Fig. 17 Base Plate Cut joint from the Base Plate category

III.3. "Tube Base Plate" - This is a connection for the columns that have a round or rectangular section.

IV. The last connection category is "Bracings".

IV.1. "Gusset Plate at One Diagonal" - The joint is created using a gusset welded to the beam or column and bolted or welded to the bracing (Fig. 19).

IV.2. "Gusset Plate for 2 Diagonals" - a similar joint that connects two bracings using the same gusset (Fig. 20).

IV.3. "Gusset Plate for 3 Diagonals" - This joint connects three bracings using the same gusset (Fig. 21).
