No it won't. It will with much more heat ... LOTS more. 100 degrees would be like a beam exposed to the winter cold on one side and room temperature on the other. I don't believe many buildings collapse from that.
Again, car exhaustt systems and barbeques are made from this mysterious substance with butterlike qualities you people read about but evidently have never seen or touched.
Sure it's January but go out on the deck and fire up the barbeque and experiment with trying to melt or warp it. Get that sucker to collapse, i'll wait.

Double checked, it was 300, not 100. And fortunately, no part of my grill that heats up is responsible for bearing the weight of more than ten or twenty pounds. the idea that a difference of a few hundred degrees from one side of a beam to another could warp it enough to cause a collapse isn't mine, it's from a professor of materials engineering at MIT, whose job it is to know about that kind of thing.
And if the difference between winter cold and room temperature is 100 degrees, I'd hate to live where you do.
