Your options in timber design are diverse. You can consider cut-to-grain angles, transverse tension stresses, and volume-dependent radii of curvature for tapered and curved members. To design the area of the grain cut, the strength is adjusted accordingly in the case of bending tension or bending pressure. In order to also allow you to perform a stability analysis with the equivalent member method, the height to determine the effective and lateral-torsional buckling lengths is set at a distance of 0.65 × h to the actual design point.
Are you looking for models for your design? Then you have come to the right place at the Dlubal Center. It contains an extensive database with partly parameterized models. These include, for example, trusses, glulam beams, tapered frames, or tower segments. You can import these models and, if necessary, modify them according to your individual requirements. Furthermore, you can save the models as a block for later use.

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.

The design analyzes tension and compression along the grain, bending, bending and tension or compression, and shear due to shear force with and without torsion. Designs proceed at the level of design stress values.
The design of structural components at risk of buckling or lateral buckling is performed according to the Equivalent Member Method and considers the systematic axial compression, bending with and without compression force as well as bending and tension. The deflection of inner spans and cantilevers is determined in characteristic and quasi-permanent design situations.
Separate design cases allow for a flexible and stability analysis of members, sets of members, and loads. In the case of tapered members, the cut-to-grain angle is considered in the bending tension and bending compression area. If there is a ridge defined, the module performs the ridge design additionally.
The details for the lateral-torsional buckling analysis are defined separately for members and sets of members. The following parameters can be set:
Support Type/Lateral-Torsional Buckling Load
Available options are Lateral and torsional restraint, Lateral and torsional restraint or Cantilever
Special supports are possible by specifying the degree of restraint βz and the degree of warping restraint β0. In this section as well, you can consider the elastic warping restraint of an end plate, a channel section, an angle, a column connection, and a beam cantilever by specifying the geometry dimensions.
As an alternative, it is also possible to enter the lateral-torsional buckling load NKi or the effective length sKi directly

Alternatively, you can enter the shear panel stiffness Sprov directly

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.
Full integration in RFEM/RSTAB including import of all relevant internal forces
Intelligent presetting of flexural buckling-specific design parameters
Automatic determination of the distribution of internal forces and classification according to DIN 18800, Part 2
Optional import of buckling lengths from the RF-STABILITY/RSBUCK add-on module. For this, a comfortable graphical selection of the relevant buckling mode is possible
Optimizing Cross-Sections
Optional calculation according to both design methods of DIN 18800, Part 2
Automatic determination of the most unfavorable design location, also for tapered members
Check of c/t-limit values according to DIN 18800, Part 1
Design of any thin-walled RFEM/RSTAB or SHAPE-THIN section for compression and bending without interaction according to the elastic-plastic method
Design of I-shaped rolled and welded sections, I-like sections, box sections, and pipes subjected to bending and compression with iteration according to the elastic-plastic method
Clearly arranged, comprehensible design checks with all intermediate values in the short and long forms
