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 as an approximation. It is provided using the user-input option. The max. strength in tension is around 1000 psi. However, after analysis, the output stress plot shows all points at a higher stress level. I cannot understand how is that possible.
The loading consists of:
End displacement of -1.38" at the left end
Temperature decrease of 50.8F
I've also tried using steel (Grade 60) as the material, in which case output stresses are of the order of 10^9 psi. Somehow, the output stresses appear to be much higher than the material strength. I've checked the units in each case. Please suggest how can I fix this.
I've attached my model here.
Thanks in advance.
