Continuous Beam Steel
The STM+ program is used to calculate single-span and multi-span steel beams. A cantilever beam is selectable as a special case. Cross-sections can be defined with a haunch, with hinges or with a reinforcement, also multi-part cross-sections are possible. The user can optionally perform either an elastic or plastic design of the cross-section in accordance with EN 1993. The output is compact and can be configured in a detailed manner. The program is designed for a graphically supported interactive workflow.

The user can optionally perform either an elastic or a plastic design of the cross-section. For the equivalent member verification, various options are available for selection. When the cross-sectional dimensions of the steel shape are known (e.g. from the Frilo profile selection file), the edge stresses, the highest shear stress and the comparison stress are verified in each cross section.
Instead of a continuous restraint, the position of restraints in the longitudinal direction of the beam and on the cross-section can be defined. The stability analysis for uniaxial bending without normal force is then carried out for the beam. This verification is issued separately in the program.
For the verification of deformation, the user can optionally select the characteristic, frequent or quasi-permanent design situation. Optionally, deformations from shear can be considered in the calculation. The serviceability verification can be put out optionally with the difference in deformation compared to the undeformed system and/or related to the system lengths. The limit values for the span and the cantilevers can be adjusted separately.
STM-2: Biaxial Bending
With the help of this add-on, the user can define biaxial loading and perform the corresponding design. Each load can apply at an angle between 0° and 90°. The loads are automatically separated into a horizontal and a vertical load share. The user can define elastic supports, restraints in upright members and end restraints as well as column settlement in each direction separately. Joints function as bending joints about the y-axis as well as about the z-axis.
