Not yet, but maybe in the future.
There are a number of attributes that make materials desirable in constructing buildings. There are also various different ways to measure strength.
Steel has been and will remain the dominant construction framework material for the near future because it has high strength, reasonable anti-corrosion characteristics (when properly managed), and low cost. Steel has high strength in terms of both compression strength and yield strength, both are important.
What about alternatives?
Aluminum. Although stronger on a per mass basis, it is not as strong on a volumetric basis. A rule of thumb is that steel is twice as strong as aluminum, but aluminum only weighs about 1/3 as much as steel - both are available of alloys of different strengths. Aluminum also fails under cyclic loads and is more brittle (breaks at around 3% yield vs 20% yield for steel). Aluminum has an additional unsatisfactory problem for construction though, typical alloys lose much of their strength at 400 degrees F. This is simply a fatal flaw for building construction.
Titanium: Stronger per unit mass, but more expensive and considerably harder to work. Although abundant in the crust, much less than a million tons annual world production vs. over a billion tons for steel (about 10000:1 ratio overall). Does not have the high temperature strength of steel, but is better than aluminum. Titanium is very reactive, it will even burn in a burn nitrogen atmosphere. Titanium is popular where lightness and strength are dominant goals, such as fighter jets, but simply too expensive to use for building framing.
Superglass: Currently the superglass materials you refer to depend upon palladium. Palladium is expensive - today price 495.40 USD per ounce, 15,927 per kg. This glass will never be cheap enough for building construction unless the palladium can be replaced by something quite a bit cheaper. At which point, it may in fact become a common building material over time.
This superglass is not the same glass that we are all familiar with. The palladium allows the glass to be tough (bend without breaking) and retain its traditional strength. Some glass loses strength rapidly as temperature increases, other glasses actually get stronger for modest temperature increases. Without knowing the details for superglass, I can't guess this aspect and could not find any published detail related to strength at high temperature.
