Efficient Precast/Prestressed Floor System For Building Construction, Eliya Henin
Efficient Precast/Prestressed Floor System For Building Construction, Eliya Henin
Department of Construction Engineering and Management: Dissertations, Theses, and Student Research
Precast floor systems provide a rapidly constructed solution to multi-story buildings that is economical, high quality, fire-resistant, and with excellent deflection and vibration characteristics. Conventional precast concrete floor system cannot compete with cast-in-place post tensioning flat slab floor systems when high span-to-depth ratio and flat soffit are required. This is due to the significant depth of standard precast beams, and use of column corbels and beam ledges. This research presents the development of a new precast concrete floor system that eliminates the limitations of conventional precast floor system and provides a competitive precast alternative to cast-in-place flat slab floor systems. …
