Hybrid prestressed concrete beams providing flexibility for building services

Modern buildings must increasingly ensure that technical installations be accommodated in the available intermediate floor space. Precast prestressed concrete beams can be used as an alternative to steel or composite steel beams with large openings. In their conventional design, the insertion of the reinforcing steel around their openings is very costly and time-consuming. As part of an AiF research project, a hybrid prestressed concrete beam with large openings was investigated in which easy-to-install, extensive reinforcing elements (perforated plates) were used in combination with steel...
