Abstract

Total number of seven experimental specimens of size 4.6m$\times$2.4m are designed in full scale with due considerations given to the constructability as well as economic applications. Each specimen is made with different shapes of trusses or hooks along the interfacial surface between precast panel and topping concrete to maintain appropriate shear resistance. Structural performances in terms of strength and ductility under flexural load are examined for each specimen with different types of interfacial shear resistance reinforcements. Experimentally obtained flexural strength are also compared with those of analytical predictions. Based on experimental and analytical studies, design equations are suggested for the developed precast prestressed concrete half-slab systems.
