To be more specific I would like to see pictures of large steel beams similar to those used to contruct the world trade center buildings 1 and 2 so that I can compare the effect it has on the steel to that of the photos of steel people are talking about in a photo of Ground Zero that were cut at a 45 degree angle, and have slag on the outside of the beam. Welders tell me it should be on the side you are cutting through, not the side you are starting on. The photo I have questions about is here:

Please if you have professional knowledge of demolition, welding, or steel working, respond with your expertise.
Besides the video/pics I am looking for, Here are my questions:
Why would clean-up crews cut remaining beams at a 45 degree angle?
What does a purposely demolished steel beam look like after being cut with thermite/thermate?
Steel weakens at about half its melt temp, what if it is load bearing, any formulas?
Thanks
