The melting you see are not aluminum stringers. All areas of metal that could possibly be affected by a fire are coated with coating that swells during a fire and creates an insulating effect to any bulkheads or pathways for evacuation routes. The underside of the heliports are coated as well in case of a crash or helo fire. It's a required CFR regulation and USCG requirement. The bridge was under the heliport if I remember correctly. The whole you are referring to was likely to have been cause by a nearby boat spraying water from their firewater cannons to help cool bulkheads during evacuation. If was already hot and on the verge collapsing, the water hitting it could've caused that. There was no secret laser from space dude, get over it.
