Reinforced Concrete Column

BEST – Option Reinforced concrete column

The program FUNDA for foundations and the program BEST for column design of RIB are proven basic applications in our office. In addition to the well-known good quality of the results, the new operation and the clear and designable printout are convincing. We are glad to use the effective load transfer from BESTf or foundations. We have been using BEST successfully for more than 30 years and have accompanied the development with pleasure.

New features of BEST reinforced concrete column

The calculation and design core of the BEST column program has been completely revised and is available from version 21 with many new features. These include, above all, the changeover from a system-based to a cross-section-oriented design approach for the economic design of columns, even with high-strength materials. Read more about the other innovations in BEST here:

  • New FEM calculation with high-quality geometric and material nonlinear stability and ultimate load analysis of plane and spatial column systems.

  • New design kernel with cross-sectional approach for creep redistribution between reinforcing steel and concrete as well as cold and hot design of reinforced concrete columns

  • Separate checks and utilization levels of the cross-section load-bearing capacity and global system load-bearing capacity with regard to buckling

  • Coordinate origin at column base with x-axis as column axis and cross-section axes y,z as reference for uniform input (cross-section, reinforcement, loads, eccentricities) and output (internal forces, deformations, stiffnesses)

  • Support forces and foundation loads referenced to the global coordinate system for compatible load transfer to other applications

  • Backward compatibility for files from previous versions

  • Setting for calculation of bearing action in x-z plane or spatially

  • Automatic calculation of the proposal for the size of the pre-deformation

  • Material grading for concrete and reinforcing steel in user-defined column sections

  • Consideration of new reinforcement schemes

  • Consideration of self-weight with a separate load case

  • New combination formation for cold and hot design as well as GzG checks

  • Selection between design (experienced As) and verification mode (existing As) without design

  • Economic design for high-strength steel SAS670 due to creep redistribution

  • Deformation check in SLS, which can be performed with the selected combinations (rare, frequent, quasi-permanent). The calculation is performed non-linearly with average values of material properties and without imperfection.

  • Free choice of the flamed edges in the zone method of the fire protection verification.

  • Verification of the system conditions for the tabular fire protection proof

  • Tabular fire protection verification for selected fire combinations

  • New thermal analysis with finite difference method for rectangular cross sections

  • Exact temperature determination for each individual reinforcement position

  • New hot design with differentiated temperature-dependent material characteristics for each reinforcement position

  • Fast verification overview before generating the results output



  • Reinforced concrete design in compliance with DIN, EN according to national annexes for DE, AT, SK/CZ and UK
  • Calculation according to linear and non-linear theories, considering effective stiffnesses in the cracked state
  • Biaxial bending design with normal force and shear
  • Standard cross section for rectangular, U, H, circular and ring-shaped elements
  • Option fire design with consideration of thermal deformations for reinforced concrete columns
  • Option for haunched, polygonal cross-sections, centric prestressing and user-defined material characteristics
  • Automatic generation of load combinations
  • Consideration of different erecting states
  • Reinforcement grading, easy to create reinforcement drawing
  • Predeformation affine to the buckled shape or in a skewed shape
  • Taking creep deformations into account
  • Rigid or elastic supports
  • Option of configuring the program and setting different languages DE, UK & CZ for the input and output list
  • Simple and clear evaluation of results, e.g. as short list and long list



The option RC-column of BEST for standard cross sections is a powerful structural engineering application and in particular provides the following advantages:

  • clearly arranged and efficient working surface for short processing times
  • fully graphic-oriented input with optimum control of all modifications
  • fast familiarisation with an online support and manual
  • simple calculation and design of arbitrary systems with free option for storeys, supports and loads
  • high-quality calculation module for the processing of very slender, highly utilised columns
  • foundation loads can be transferred to the programme FUNDA

BEST is particularly suitable as an application for high-quality, geometrically and materially nonlinear calculation as well as for the economic design of column systems.
