Hi
One method tested is water filled steel tube frameworks.
When water is made into steam it requier quite a lot of energy and as we all know, as long as the water is not under preasure, the temperture will not rise above 100 deg celcius, still there need to be taken care for preasure release and with a highrise building, the hight of the building will add one atm. for each 10 meters the bulding is high.
Still it is my oppinion that even this mean extra costs then with the right building method this need not be a problem. We think about steel tubes as standard extruded tubes and to come around the problem of 100 deg.c. warm steam coming out, we need an inner tube to lead away the preasure , beside a highrise building proberly need to be sectioned to make sure a 100 meter building don't argue 10 atm. at the bottom just in water preasure .
Please check how sections in a 3D-H make an end to the problems sectioning the preasure, and make sure no air locks exist in a structure made from non-standard tubeworks with an inner core that will allow for less water and escape core.
