Splice Connection
SLS+
The SLS+ program is used to design single-axis stressed bolted girder joints with splices. It allows the definition of splice connections that are characterized as rigid, flexible and hinged. DIN EN 1993 is available for dimensioning with German and Austrian national annexes. In addition to entering several load case combinations, different cross-sections and steel grades can also be defined for each member. Furthermore, it is possible to define different bolt sizes and strengths as well as different arrangement of the bolts in the respective splices. A beam offset can be specified between the member on the right and left.

SHOW MOREMaterial
The material can be selected differently in the member on the right and left as well as in the straps. The following materials are available:
- Structural steel (S235, S275, S355, S450)
- Structural steel annealed (S275N – S460N)
- Structural steel thermo (S275M – S460M)
- Structural steel weatherproof (S235W – S355W)
- Creep resistant steel (S460Q – S460QL1)
- Hollow section warm (S235H – S355H)
- Hollow section N (S275NH – S460NH)
- User-defined steel type
Structural System
Joint configuration
- Rigid joint with web splice plates and chord straps
- Flexible joint with chord straps
- Hinged joint with web splice plates
An offset of the member axes can be considered between the members.
Cross-sections
Rigid joint:
- Beam sections
- I-sections as standard sections
- I-sections as user-defined sections
- The sections can be defined differently in the members.
- Straps
- Rectangular section as user-defined cross-section
- In addition to the external straps, internal straps can optionally be arranged on the chords.
Flexible joint:
- Beam sections
- I-sections as standard sections
- I-sections as user-defined sections
- Flat steel as standard section
- Flat steel as user-defined section
- The sections can be defined differently in the members.
- Straps
- Rectangular section as user-defined cross-section
Hinged joint:
- Beam sections
- I-sections as standard sections
- I-sections as user-defined sections
- Flat steel as standard section
- Flat steel as user-defined section
- The sections can be defined differently in the members.
- Straps
- Rectangular section as user-defined cross-section
Loading
Design internal forces for joint calculation
- Nd, Vzd and Myd (rigid / flexible joint)
- Nd and Vzd (hinged joint)
- Input of several design internal force combinations possible
Fasteners
The bolts can be selected differently in the web splice plates on the right and left member as well as in the chord straps above and below.
- Bolts (black bolts as well as fitted bolts)
- Sizes: M12, M16, M20, M22, M24, M27, M30, M36
- Strength classes: 4.6, 5.6, 8.8, 10.9
The program carries out the verifications required for the selected joint type in accordance with the selected design standard DIN EN 1993-1-8.
- Verification of shearing off the bolts
- Verification of bearing
- Cross-section verification
- Verification of local stability under compressive stress
