How can I conduct a proper modal testing on a beam?

I intend to conduct a modal testing on a clamped-clamped steel beam in ABAQUS. -The input is random signal with normal distribution, zero mean, and maximum amplitude of 5 (N). -Duration of loading...

Would anyone suggest me a paper on the effects of temperature on natural frequencies of a beam?

I need to verify my models in ABAQUS, so I need a paper as a reference, what I need is properties of the beam's material, clear thermal loads, and the frequency changes. thanks in advance.
