Different methods are available for calculating the deformation in the cracked state. RFEM provides an analytical method according to DIN EN 1992-1-1 7.4.3 and a physical-nonlinear analysis.
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
- What is the effect of the settings "Approach of pure tension restraint," "Approach of bending restraint," or "Depending on the defined load" for the determination of the minimum reinforcement As,min due to restraint?
- Is it possible to enter and design a reinforced concrete surface with a reinforcement layer in the center of the surface?
- Is it also possible to perform a deformation analysis in cracked state for a 2D model in RF‑CONCRETE Surfaces?
- I obtain different results when comparing the deformation analysis in the RF‑CONCRETE add-on modules and another calculation program. What could be the reason for this?
- In the add-on module RF-CONCRETE Surfaces, is it possible to limit crack widths due to internal restraint and with customized fct,eff?
- Why is the button of "Design Details" not active in RF‑CONCRETE Surfaces?
- When converting from the manual definition of reinforcement areas to the automatic arrangement of reinforcement according to Window 1.4, the result of the deformation calculation differs, although the basic reinforcement has not been modified. What is the reason for this change?
- Is there a possibility in RFEM 5 or in RF‑CONCRETE Surfaces to calculate walls as sandwich elements ?
- When starting the calculation in RF‑CONCRETE Surfaces, I get the error message "Failed to calculate the deflection for the result combination." Why? What can I do to solve this problem?
- How to calculate the static depth d when designing the bending of block foundations (calculation as an equivalent beam)?
