Beam Deflection due to temperature

[5234185]

I am a Geotechnical Engineer and need some guidance.
A 40 foot long steel beam (415) is fixed at one end and other end is simply supported. Will there be any deflection (vertical) in the beam due to change in temperature. The beam is allowed to move at one end. I have a dial gauge with precision of 1000th of an inch.
I think beam will deflect under its own weight. How about deflection with temperature. Will there be any deflection I should be concern about?

You should find a copy of Roark's Formulas for Stress and Strain; Chapter 7 covers flexure of beams. The example problem shows a deflection of about 80 mils for a 30 ft beam, with the example conditions.
