Hello everyone

I did one model (bridge with 2 spans) with beam elements. I obtained all the Loads cases as 4XXX, 5XXX, 6XXX, 7XXX, 15XXX and 16XXX. The 7XXX Loads cases represents the “real stress” in the structure. However, I did the same model with quad elements, and I obtained only the 4XXX and 5XXX Loads cases. So, I didn’t have the effect of the pre-stress losses due to creep and shrinkage (LC 6XXX) in my quad model isn’t it ?

I read the notice and if I understood well, it stipulated inside that for beam model we use the AQB module and for quad model we use the BEMESS module.

To have the effect of the creep and shrinkage I used the CSM task. In the notice of the CSM module it’s writted that to have the creep and shrinkage effect for quad element we can added the command CREP … DEFQ to define the effective member thickness to calculate the effect of the creep and shrinkage.

However, I do so and it didn’t change anything

So, I would like to now if it’s possible to obtain the effect of the creep and shrinkage in quad a model ? It’s possible to obtain LC 7XXX as for the beam model with the “real stress” of the structure” at any construction stage ?

Thank you for your help

Sincerely

Antoine
