Seismic Resistance of Composite Floor Diaphragms
Research to determine the behavioral and strength characteristics of composite steel deck floor slab diaphragms is reported. Principal characteristics investigated include maximum load, ductility, stiffness, and failure mode. The research program comprises three phases: (1) designing a full-scale research facility for in-plane loading of composite slab diaphragms and conducting two pilot tests; (2) testing of full-scale composite slabs with in-plane loading only; and (3) testing of one-way slab elements with vertical loads to determine the influence of stud shear connectors on shear-bond strength. Initial test results show that the addition of studs increases the flexural load capacity of one-way steel deck reinforced slabs by 10 to 30 percent. Non-studded specimens ultimately fail because of loss of interfacial force in the shear span. Studded specimens ultimately fail due to tearing of the deck near the stud. Two analysis procedures were used, a contributing forces approach and a shear-bond approach. The former was found to be a potential analysis procedure, and results from the shear-bond increase approach demonstrated its feasibility for studded specimens.
