The Verification Example 10 Update the E-Modulus (action UpdEmod) has the objective to verify the action UpdEmod on a simple system. This action stores the difference between the calculation with an E-Modulus of 28 days and an E-Modulus of 7 days into a new loading case. The differences in the results highlight the analysis capacity to include all possible deformations despite the modeling assumptions and simplifications. The structural models used are of one single prestressed beam, simply supported or fixed, as shown below. The differences arise in the case of prestressed structures and the user should consider when it is necessary or not to include them.
