OK, here are some questions. A steel-framed high-rise building has been on fire for two hours. The fire is massive, but confined to the exterior. What are we seeing? Two hours later, is there any sagging, melting, deformation, or collapse? Everyone should be asking those questions, regardless of what the answer is.
Have the firefighters pulled out of the building? If they think the building is going to collapse, why are they still planning on putting on a massive fireworks show? Wouldn't they want to get everyone out of the streets as far away from the building as possible? If they don't think the building will collapse, why do they think this? Is it because steel-framed high-rise buildings don't collapse from fire?
