Butt Plate Joint

SPS+

The SPS+ program is used to design moment-resistant, bolted butt plate joints in steel construction. The butt plate joint can be defined flush or projecting and with two or four vertical bolt rows. Furthermore, an inclination of the beam can also be considered.

Structural system

Connection configuration:

Butt plate joint flush or projecting on one side and with two or four vertical bolt rows
An inclined beam is possible
The user can specify the thickness of the butt plates, their geometry as well as the bolt patterns or select a connection from the catalogue of connection configurations

Cross-sections:

I-sections as standard shapes
User-defined I-sections

Loads

Design internal forces from axial force, moment and shear force
Multiple combinations of design internal forces can be entered

Fasteners

Bolts (black bolts and fit bolts)
Sizes: M12, M16, M20, M22, M24, M27, M30, M36
Strength classes 4.6; 5.6; 8.8; 10.9

Design

The calculation is based on the component method as per DIN EN 1993-1-8. For the verification of but plate joints with four vertical bolt rows, the model described in the following publications is used:

Research Report 3/2009: Entwicklung eines Bemessungsmodells für geschraubte momententragfähige Kopfplattenverbindungen mit vier Schrauben in einer Schraubenreihe auf der Grundlage der prEN 1993-1-1:2003; Deutscher Ausschuss für Stahlbau DASt, Düsseldorf
WAGENKNECHT: Stahlbau-Praxis nach Eurocode 3, Band 3 Komponentenmethode, 2nd edition; Beuth Verlag GmbH, Berlin, Wien, Zürich 2017

Either the elastic or plastic cross-sectional resistance is verified.
