Using the "Rib" component, you can define any number of longitudinal ribs on a member plate. By defining a reference object, you can automatically specify welds on it.
The "Rib" component can also be arranged on circular hollow sections. Dafür wird zusätzlich die Vorgabe der Winkel zwischen den Rippen benötigt.
The Concrete Design add-on provides you with the option to perform the simplified fire resistance design according to EN 1992‑1‑2 for columns (Section 5.3.2) and beams (Section 5.6).
The following design checks are available for the simplified fire resistance design:
Columns: Minimum cross-sectional dimensions for rectangular and circular sections according to Table 5.2a as well as Equation 5.7 for calculating time of fire exposure
Beams: Minimum dimensions and center distances according to Table 5.5 and Table 5.6
You can determine the internal forces for the fire resistance design according to two methods.
1 Here, the internal forces of the accidental design situation are included directly into the design.
2 The internal forces of the design at normal temperature are reduced by the factor Eta,fi (ηfi), then used in the fire resistance design.
Furthermore, it is possible to modify the axis distance according to Eq. 5.5.
The Steel Joints add-on provides you with the option to connect circular hollow sections using welds.
It is possible to connect the circular sections to each other or to planar structural components. The fillets of standard and thin-walled sections can also be connected with a weld.

SHAPE-THIN includes an extensive library of rolled and parameterized cross-sections. They can be composed or supplemented by new elements. It is possible to model a section consisting of different materials.
Graphical tools and functions allow for modeling complex section shapes in the usual way common for CAD programs. The graphical entry provides the option of setting point elements, fillet welds, arcs, parameterized rectangular and circular sections, ellipses, elliptical arcs, parabolas, hyperbolas, spline, and NURBS. Alternatively, it is possible to import a DXF file that is used as the basis for further modeling. You can also use guidelines for modeling.
Furthermore, parameterized input allows you to enter model and load data in a specific way so they depend on certain variables.
Elements can be divided or attached to other objects graphically. SHAPE-THIN automatically divides the elements and provides for an uninterrupted shear flow by introducing dummy elements. In the case of dummy elements, you can define a specific thickness to control the shear transfer.

When entering the structural model, you can define single-span and continuous beams with or without cantilevers. Furthermore, it is possible to specify different span lengths with definable boundary conditions (supports, releases) as well as any construction support and moment release in the construction stage. For a complete cross-section, you can create typical composite beam sections on the basis of steel girders (I-sections) with solid concrete flanges, precast plates, trapezoidal sheets, or tapered solid ceilings.
It is also possible to grade cross-sections by means of beam lengths, optionally with concrete encasement. Illustrative figures facilitate the entry of additional transverse reinforcements for trapezoidal sheeting, profile stiffeners, and angled or circular openings in the web. The self-weight is applied automatically when entering loads. In addition, it is possible to consider fixed and variable loads by specifying the concrete age at the beginning of loading for creeping, and to define single, uniform, and trapezoidal loads freely. COMPOSITE-BEAM automatically creates a load combination based on the data of individual load cases.

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.
Surfaces with moving loads are selected graphically in the RFEM model. You can apply loads with several different sets of movement on one surface at the same time.
The 'lane' is defined by means of line sets. You can select them graphically in the model. In addition, you can enter the increment of the individual load steps. Several load types are available; for example, single, linear, rectangular, circular, and various axle loads. They can be applied in local and in global directions.
The different loads are summarized in load models. The module assigns defined load models to the sets of lines and creates individual load cases based on these data.
