World's Tallest Building to Soon Open in Dubai--(think they've accounted for Thermal-Expansion?)

I was wondering if anyone here has the expertise or knowledge of new building construction since the discovery of "Thermal Expansion," which, according to NIST, of course, can bring down a building in a symmetrical, free fall speed collapse, due to small fires only.

Have new construction codes been put in place? I have yet to hear of any.
