Steel hoping to move into condominiums

In an effort to stimulate more use of steel structures in high residential buildings, the American Institute of Steel Construction recently sponsored a competition for innovative ideas.
It has given the $10,000 prize to a system, proposed by Keith Itzler of Goodkind & O’Dea in New York City, for a composite floor system incorporating structural steel and autoclaved aerated concrete.
A $5,000 second prize was awarded to Patrick M. Hassett of Hassett Engineering in Castro Valley, California for a stiffened plate floor deck. It uses a relatively think deck plate stiffened by “closed” ribs similar to a deck system used in orthotropic steel bridge decks. The competition brought entries from architects, students, builders and engineers.
