In the Steel Joints add-on, you can classify the joint stiffness.
In addition to the initial stiffness, the table also shows the limit values for hinged and rigid connections for the selected internal forces N, My, and/or Mz. The resulting classification is then displayed in tables as "hinged", "semi-rigid", or "rigid".

The RX- TIMBER Continuous Beam program is suitable for the design of single-span and continuous beams as well as hinged girder systems (Gerber) with or without cantilevers.
Geometry, material, cross-section, action, and imperfection data are entered in clearly arranged input windows:
Geometry
Quick and convenient data input
Definition of support conditions based on various support types (hinged, hinged movable, rigid, and user-defined, as well as lateral on upper or bottom flange)
Optional specification of warping restraint
Variable arrangement of rigid and deformable support stiffeners
Possibility to insert hinges
CRANEWAY Cross-Sections
I-shaped rolled cross-sections (I, IPE, IPEa, IPEo, IPEv, HE-B, HE-A, HE-AA, HL, HE-M, HE, HD, HP, IPB-S, IPB-SB, W, UB, UC, and other cross-sections according to AISC, ARBED, British Steel, Gost, TU, JIS, YB, GB, and others) combinable with section stiffener on the upper flange (angles or channels) as well as rail (SA, SF) or splice with user-defined dimensions
Unsymmetrical I-sections (type IU) also combinable with stiffeners on the upper flange as well as with rail or splice
Actions
It is possible to consider the actions of up to three simultaneously operated cranes. You can simply select a standard crane from the library. You can also enter data manually:
Number of cranes and crane axles (maximum of 20 axles per crane), center distances, position of crane buffers
Classification in damage classes with editable dynamic factors according to EN 1993-6, and in lifting classes and exposure categories according to DIN 4132
Vertical and horizontal wheel loads from self-weight, hoist load, mass forces from drive, as well as loads from skewing
Axial loading in driving direction as well as buffer forces with user-defined eccentricities
Permanent and variable secondary loads with user-defined eccentricities
Imperfections
The imperfection load applies in compliance with the first natural vibration mode - either identically for all load combinations to be designed, or individually for each load combination, as mode shapes may vary depending on the load.
Convenient tools available for scaling the mode shapes (rise determination of inclination and precamber).
RX- TIMBER Column designs hinged columns (optionally with elastic head or footing restraint) and brackets (optionally with elastic foundation of the footing column).
For this, circular and rectangular cross‑sections are available in the program.
Initially, it is necessary to define material data, panel dimensions, and boundary conditions (hinged, built-in, unsupported, hinged-elastic). It is possible to transfer the data from RFEM/RSTAB. Then, boundary stresses can be either defined for each load case manually or imported from RFEM/RSTAB.
Stiffeners are modeled as spatially effective surface elements that are eccentrically connected to the plate. Therefore, it is not necessary to consider the stiffener eccentricities by effective widths. The bending, shear, strain, and St. Venant stiffness of stiffeners as well as the Bredt stiffness of closed stiffeners is determined automatically in a 3D model.
The Hinged Column Footing category provides four different base plate connections:
Simple column base
Tapered column base
Column base for rectangular hollow sections
Column base for circular hollow sections
The Restraint Column Footing category provides five different joint layouts of I-sections:
Base plate without stiffening
Base plate with stiffeners in center of flanges
Base plate with stiffeners on both sides of column
Base plate with channel sections
Pocket foundation
All connection types include a base plate welded around a steel column. Connections with anchors are set in concrete within the foundation. You can select anchor types M12 – M42 with steel grades of 4.6 – 10.9. The top and bottom sides of the anchors can be provided with round or angled sheets for better load distribution or anchorage. In addition, you can use rectangular or circular anchor heads with threads applied at the member ends.
The material and thickness of the grout layer, as well as the dimensions and material of the footing, can be set freely. Furthermore, you can define edge reinforcement of the footing. For a better transfer of shear forces, it is possible to arrange a shear key (cleat) on the bottom side of the base plate.
Shear forces are transferred by a cleat, anchors, or friction. You can combine the individual components.
