Continuous Beam

DLT+ can be used to calculate single-span and continuous beams for reinforced concrete, steel and timber with an unlimited number of spans, with or without cantilevers. Cross-sections can be constant or variable. Joints are also possible. In addition to the optically adapted interface, easier operation, a clear and detailed customizable output, the program offers a completely revised interactive reinforcement guide.

Beam types
  • Reinforced concrete slab (with reinforcement layout as additional option BTM-BEW)
  • Reinforced concrete beam (also biaxial as additional option BTM-2 and with reinforcement layout as additional option BTM-BEW)
  • Steel beam (also biaxial as additional option STM-2)
  • Timber beams (also biaxial as additional option HTM-2)

Depending on the selected material, the cross-section definition is adjusted. Depending on the material, haunches and cross-section discontinuities, block-outs or multi-part/rotated/reinforced cross-sections can be defined, for example. The selection from the FRILO steel database is also available for steel cross-sections.


Standard loading and multi-span loading can be defined as uniformly distributed load, concentrated load, concentrated moment, trapezoidal load and triangular load.


Detailed information

DLT+ combines all beam types/materials of the individual programs BTM+, HTM+ and STM+ in one program.

Therefore, you will find detailed information under

Continuous Beam Concrete BTM+
Continuous Beam Timber HTM+
Continuous Beam Steel STM+


For concrete, steel and timber, the program carries out the design or the stress analysis for the preselected cross-section dimensions.
