FEM-System for rolled beams in concrete incl. TRIMAS fem

New features

In addition to the ability to run under Windows 11, the following new features are available in version 22:

  • For neck fillet welds of welded open or closed cross-sections, the required weld thickness in the ultimate limit states and fatigue is determined according to the simplified method, taking into account the minimum weld thicknesses.
  • For the fatigue check, the notch cases are specified separately for the top and bottom chords.
  • The required seam thicknesses are displayed graphically along the beam.
  • Optionally, the requirements according to RE-ING can be considered for tightly welded hollow boxes.
  • For rolled beams in concrete, the determination of shrinkage forces and shrinkage moments is made possible according to 3 different methods, which take into account the uncracked or cracked state or the average of both states.

The following new features are available since version 21:

  • Setting of variants for secondary construction stages is now done automatically. The n0 cross-section variants are replaced by the corresponding cross-section variants of the secondary construction stages.
  • When creating a new steel composite cross-section, the variants nP, nPT, nS and nD are generated automatically. For the new WiB cross sections, these are the corresponding variants for positive My.
  • For all cross-sections, it is now possible to specify an analysis and design time. The calculation of the creep and shrinkage coefficients and the reduction ratios can be optionally performed for this purpose. In the composite design, this time of consideration is displayed in the tree view.
  • For the longitudinal shear capacity of head bolt dowels in the composite joint, verification method 1 is now extended by verification method 2, which also takes into account the non-elastic composite behavior (MEd > Mel,Rd) between longitudinal shear force and shear force for class 1 and 2 cross-sections.

Bridge construction system PONTI for rolled beams in concrete

Integrated software solutions for rolling beams in the concrete according to DIN FB 101-104 and EN 1991-EN 1994 with corresponding NAs for DE, UK, CZ/SK, AT. The cross-section module supplements the basic solution for steel composite bridges and supports the special input, calculation and design options of WIB bridge girders. The following effects are considered:

  • The influence of concrete cross sections on positive and negative moments in the cross-section variants in the cracked state
  • The selection of calculation variants for the special determination of the reduced numbers of rolled beam in concrete cross sections

In addition to that, all checks described in the basic module of composite steel bridge girders are carried out in the ultimate limit state, fatigue limit state, serviceability limit state.


Benefits of PONTI compositesteel WIB

The program solution PONTI compositesteel WIB supports the calculations and designs of mixed spatial systems of structural steel, composite steel or reinforced concrete and offers the following advantages in particular:

  • Dimensioning with interactive optimization
  • Calculation and design of WIB beams with a total cross-section method
  • Recording system history, cross-section history, and load history
  • Verification of crack formation in the concrete belt (ZII-variants)
  • Automatic determination of effects from creep and shrinkage
  • Economic dimensioning according to DIN-EN, EN, and DIN-FB
  • Clear graphic results and targeted detailed information
  • Document output according to user specifications
