Strut-and-Tie Model Reinforced Concrete

BSM+

The BSM+ program generates strut-and-tie models for the design of reinforced concrete components. Right-angled structures with any number of re-entrant corners as well as recesses can be calculated. In the first version of the programme, the focus is on generating stiffness-optimised strut-and-tie models with a given component geometry and load.

Basis of calculation

The basis of the calculation is a topology optimisation algorithm based on the so-called ground structure method. This method consists in finding a maximally stiff frame with as few members as possible.

Verification/quality criteria

Verification of the following quality criteria in the determination process of the strut-and-tie model:

  • Crossing compression struts – in this case the strut-and-tie model becomes invalid
  • Verification of acute angles between compression and tension struts according to the strut-and-tie modelling theory by Schlaich/Schäfer
Design

In the current version, the design and the reinforcement layout are not available yet. All member forces with the resulting horizontal and vertical load components can be put out.

Thank you for your enquiry!

The merger of FRILO Software GmbH and DC-Software GmbH with ALLPLAN, completed and announced on 1 July, is leading to an increased volume of telephone and e-mail inquiries. In addition, necessary maintenance work in our CRM and ERP systems is causing temporary irregularities and delays in our operating processes. We, therefore, ask you to forgive us for the longer waiting times. We will endeavor to process your request as quickly as possible.

Thank you for your understanding.
