Moment Connection
Moment connection according to NEN-EN 1993-1-8 + C2/NB
Calculate moment connections quickly and easily. Bolted or welded. The user interface is unique and very user-friendly. By clicking on the numbers in the dimension lines you can adjust the dimensions.
Verification according to NEN-EN 1993-1-8 + C2 / national annex
- Calculation of moment resistance Mj,Rd
- Redistribution of resistances per bolt row to determine maximum Mj,Rd
- Calculation of connection stiffness
- Display of moment-rotation diagram
- Classification of connection: rigid/flexible or hinged
- No 'black-box' calculation but clear output with written out NEN-EN 1993 formulas. The calculation can therefore also be manually checked step by step and gives you more insight into which factors are governing.
Input in the drawing
In the drawing of the connection you can change almost everything. You can change all dimensions by clicking the number in the dimension line. See Modifying Distances.
You can also change the profiles, beam lengths, beam angles and loads in the drawing. That is not only fast but also intuitive. The calculation results can be shown on the right, docked, or as a separate window on a second monitor. With every change the calculation is carried out and the results are immediately visible, so you can see the effect of your change. You have all the data in view, both the input and the calculation output.
| Field | Description |
|---|---|
| Lb | Length of the beam. This value can be changed in the drawing. It only matters for assessing the rotational stiffness of the connection (rigid / flexible / hinged) |
| Beam angle | Angle of the beam |
Connection parameters
| Field | Description |
|---|---|
| Structure classification | Sway / Non-sway. This only matters for assessing the rotational stiffness of the connection (rigid / flexible / hinged) |
| Connection type | Bolted connection / Welded connection |
| End plate type | Extended end plate / Flush end plate |
| Steel grade | Choice of the steel grade |
| Column stiffener top | None / Full / Partial. A column stiffener at the level of the top beam flange |
| Column stiffener bottom | None / Full / Partial. A column stiffener at the level of the bottom beam flange or haunch flange |
| Column web plate | None / Single / Double. Web plates or supplementary web plates for the column web |
| Bolt grade | Choice of the bolt grade |
| σcom,Ed | The largest normal stress in the column |
| Field | Description |
|---|---|
| Beams symmetrical | With a double connection (left and right) you can set whether both are identical (symmetrical) or not. You then change one side and the other side changes automatically |
| Number of bolt rows | The number of bolt rows is at least 2 |
| Bolt | Choice of the selected bolt diameter |
| Haunch top | None / Haunch without flange / Haunch with flange |
| Haunch bottom | None / Haunch without flange / Haunch with flange |
| Backing plates | Setting whether backing plates are applied |
