PONTI compositesteel WIB

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

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
