Beam-Column Connections for Precast Concrete Frames Using High Performance Fiber Reinforced Cement Composites
Precast construction system interest has been growing given the emphasis on improving work zone safety, reducing construction time and environmental impact, while maintaining the quality. The connections are the more important singularity of precast construction systems, being the general behavior of the precast structures related to their design, construction and performance. A rigid beam-column connection typology for precast construction is proposed. This typology takes advantage of the outstanding properties of the High Performance Fiber Reinforced Cement Composites (HPFRCC) and in particular its better bond conditions. The principal mechanism of connection is the splice of longitudinal beam reinforcement, which takes place at the end of the beam elements, outside the joint region. The configuration proposed avoids the interference between longitudinal and transverse reinforcement, reduces the in situ work and makes possible to define an efficient and safe construction process.
