Abstract

Two series of composite precast concrete sandwich panel (PCSP) systems containing various connector reinforcement and construction details were tested in flexure. Panels of one series utilized details  similar to certain commercially produced panels, while the second series panels contained modified details to better evaluate interface shear transfer behavior. Results of static testing indicated that a high  degree of composite stiffness and composite flexural capacity can be attained with truss girder connectors oriented longitudinally in the panels. Test results also showed that construction details can have a  significant impact on the distribution of shear in elements crossing the interface. Results of fatigue testing indicated relatively minor stiffness loss  over 55,000 loading cycles.
