    Modelling shrinkage effects in area elements

    Hi all, I'm using SAP2000 v20, and I'm using area shell-layered elements to model a pavement with two layers of reinforcement. Non-linear material properties are used to model behavior under temperature changes, concrete creep, and shrinkage effects. In the output table, I observed that the...

    Shell Stress output very high

    What would be the correct way to obtain the stress variation then? I'm looking at the S11 stress distribution at the final step with no stress averaging. The stresses seem to vary only along the length of the pavement. I didn't observe significantly higher corner stresses. I tried to plot the...

    Shell Stress output very high

    Hi All, I'm modeling a 200 m long (10.5 m wide) pavement in SAP2000 using Membrane area elements (1 m x 2.1 m). The area elements are assigned area springs to simulate friction. The material is loaded in tension. The material model used is an area average of steel and concrete models in tension...
