The Behaviour of Prestressed, Concrete-Encased Steel Portal Frames Under Load

The process of prestressing can be used to advantage in improving the general performance and load-carrying capabilities of structures of composite construction involving interaction between structural steel and concrete, whether plain or reinforced. Up-to-date, the most notable successes have been achieved with bridge decks and composite floors in order to prevent development of shrinkage cracks in the concrete or to counteract negative bending effects over the supports.
