I would like to know the formula of thermal load for steel you have on load definition based on BS5950 and BS8110.
i try to put the temperature difference of dT 10C in TZ direction and run annalysis.
i expect the emperature induced loads accounted for 10% to 20% of the total axial load though, it does account less than 1 to 2 % of the total axial load in the results.
i have the formula of it , Pt, which is following
Pt = 1.2xk x A x E x (12x10-6) x TD
1.2 = load factor
k = Thermal expansion factor = 0.8
A = Gross area of section of steel
E =Modulus of Elasticity of steel = 205 kN/mm2
TD = temp difference (C)
please help me up to solve that problem.
thanks and regards,
You should define TX instead. TZ (or TY) being the difference of temperature between top and bottom (left and right) fibers cause bending rather than tension/compression. See http://docs.autodesk.com/RSA/2012/ENU/filesROBOT/G
