Thermal Load on Bars

[jclcereno]

We are trying an Experiment for Thermal Loads on bars,

We Applied 20 deg thermal Load on A 1mx1mx10m simply supported RC bar

We are Only Anticipating 25-40kN Loads on each Support based on manual calcs but Robot Displays a whopping 6720kN

is this some sort of an error or is this right??

RSA is right.

strain = alpha x delta T = 10 ^-5 * 20 = 2 10^-4

F = E x S x strain

F = 30 000 x 1 x 1 x 2 10^-4

F = 6 MN or 6000kN
