Highlights
- Stiffness calculation with respect to the non-linear stress-strain relationships in concrete and its reinforcement.
- Input of real (practical) reinforcement or use of program-generated reinforcement.
- Modification of the calculated required reinforcement area using the multiplication factor when the program generates the amount of required reinforcement for CDD calculations.
- The program can calculate the magnitude of concrete creep deformation for selected combinations. It does this twice - once using the standard concrete modulus of elasticity, and once using the effective modulus of elasticity. The difference between the two values is considered as the creep deformation.
- Evaluation of total deformation and deformation caused by short-term loading.
Analysis of total, immediate and additional deformations in reinforced-concrete structures including the calculation of long-term stiffness according to national codes.
- Calculation of deflections based on regulations stipulated in standards.
- Long-term deflection obtained as a multiple of short-term deflection and creep coefficient.
Two-step process:
- linear calculation + input of reinforcement (can be calculated automatically) + calculation of cracks and their effect on stiffness.
- calculation with modified stiffness.
In order to calculate the long-term deflections in concrete, you need to do the following:
- Define physically non-linear concrete combinations; In fact, this is automated.
- Run a linear analysis;
- Input real (practical) reinforcement or have the program calculate the amount of required reinforcement;
- Run a non-linear analysis using the Concrete - CDD Command;
- Display and evaluate the linear/CDD results including creep deformation figures.
Long-term deflection (CDD) calculations can be performed according to Eurocode 2 + all supported national annexes.
