The use of structural steels in the last century permitted a great increase in the height of building constructions leading to modern high-rise buildings.

For low-rise buildings the most common structural solution is obtained by integrating two different load resisting systems in the same structure:

semi-rigid or pinned frames, which resist vertical actions only.
steel bracings or concrete walls and cores, which resist horizontal actions.
