Regarding a nonlinear analysis of reinforced concrete, is there any feature in the program that increases the load until failure? Or is there any way how to describe the load increment until failure?

Answer

Such a feature for increasing the load up to the failure does not exist with regard to the design of reinforced concrete structures.

As an alternative, you can proceed as follows:

Create a separate load case or load combination for each load increment. This can be done by using load factors, for example.


Then, select the individual load cases or combinations in the add-on module.


After performing the calculation to the point "Provided Reinforcement" for the first time, you can adjust and save the existing reinforcement proposed by the add-on module.


Finally, you can carry out the nonlinear analysis on the basis of the defined reinforcement.


The existing safety or the available utilization can be evaluated graphically after the successful calculation.
