Concrete coefficient of thermal expansion

[jonathan_leddy]

Hi guys,

I am trying to check properties relating to the coefficient of thermal expansion of concrete sections. If I select a panel I can see from the panel inspector that the value of LX (which I assume is coefficient of thermal expansion) = 0.00 (1/oC). I know that the value for coefficient of thermal expansion is a low number, typically 10X10-6 (10 microstrain.) so is this a display issue? When the slab has temperature loads applied it does undergo elongation / shortening as expected so there must be some value here and not simply 0. Also how do you override the material properties in Robot?

Thanks for the help,

JL

on tools/job preferences , units and formats /other / temperature , increase the number of decimals , or click o "E" button to have it on exponential format

Thanks Rafacascudo. I can also see in the preferences the modification area that allows me to input different values of thermal coefficient if needed. Thanks for the help
