Glued Laminated Girder


The D10+ program is suitable for the design and optimisation of various girder types. If the geometric conditions allow this, the plies can run in parallel to the girder top edge. The computable structural systems comprise single-span girders with one or two cantilevers.

  • Glulam of the strength classes GL20c/h to GL32c/h
Structural system
  • Parallel chord straight/curved
  • Single-pitch roof
  • Saddle roof bottom edge straight/round
  • Fish-belly circular/parabolic
  • Ridge options:
    • without saddle
    • sway saddle with raised dry joint
    • fixed saddle
  • Standard loads such as dead load, snow and traffic
  • Additional load types (concentrated and trapezoidal loads)
  • Accidental snow load is optionally available
  • Internal pressure or internal suction can be applied across spans
  • Fire exposure

Verifications are carried out for cut grains and shear stresses, for increased longitudinal edge stresses, for transverse tension and for the interaction between transverse tension and shear at ridge points as well as for axial force.

In addition, the stability against tilting and the resistance to bearing pressure and deformation are verified. A camber can be specified separately for the span and the cantilever for the verification of the serviceability.

Calculation options
  • Depending on the relevant NA, options are offered for reducing the design shear force, such as the diminution of concentrated loads in the vicinity of the supports
  • Optionally, torsion in the area of the supports due to pre-deformation can be taken into account in the shear resistance analysis including the calculation of the fork support moments
  • Transverse tensile reinforcements: automatic laying of transverse tensile reinforcements with glued-in threaded rods and fully threaded bolts including dimensioning of the drillholes to be produced along the edges of the girder
  • By specifying a distance to the lower girder edge, the user can control the spacing in the transverse tension areas and how the spacing dimensions are rounded. The weakening of the cross section is taken into consideration in the other verifications
  • Fire protection: verification of the fire resistance period
