Nonlinear System Analysis
Determination of the internal force and deformation values for reinforced and prestressed concrete as well as steel with allowance for physical nonlinearities (state 2 resp. plasticity).
- Reinforced and prestressed concrete with stress-strain-curve according to DIN 1045-1, OENORM B 4700, SIA 262 and EN 1992-1-1
- Effect of concrete on tension between cracks
- Ultimate limit state
- Check with allowance for existing reinforcement
- Serviceability limit state
- Deformations with allowance for existing reinforcement
- Consideration of long-time deformations as result of concrete creep ans shrinkage
- Steel with bilinear stress-strain-curve under consideration of the Huber - von Mises yield criterion and interaction with all internal forces
- Bilinear stress-strain-curve and individually definable compressive and tensile strength with flow conditions according to Raghava or Rankine
- Calculations in the supercritical range using the arc length method
- Calculation of load-displacement curves
- Bedding with bilinear bedding curve
- Automatic reinforcement increase during ultimate limit state check for frameworks
