Well let it be noted you obviously know what your talking about when it comes to this topicThat's what I thought. Thanks for clearing that up for me. I mig welded and used oxyacetylene torches for years and never had a symmetrical collapse of my project happen before due to some insane heat transferring to all the critical components.It's worse than that.. The heat would have had to have been concentrated all around the exterior walls at the same temp because THAT is where the designed strength was. There would have to have been very obvious sun blinding fire for an hour or two to achieve the necessary melting all at the precise moment or one wall or corner would have HAD to collapse first sending the top part leaning over and tumbling off the building.
Same for me. I started welding at age 11 and have worked with metals including all types of welding and forge for almost 50 years.
