The objective of this thesis is to analyze the behavior and strength of composite slabs with ribbed decking built with steel deck MF-50, manufactured by METFORM S. A., after concrete has been cured. A series of tests was conducted to identify and evaluate the parameters that affect this composite slab performance. The experimental program consisted of tests in 16 full scale slabs built with different height and span as well as deck thickness. The slabs were single span and were tested according international design codes for composite slabs. The analysis of the test results is based on load × endslip load × midspan deflection and load × midspan deck strains relationships. A single mode of failure was obtained in all tests: shear bond. Based on these test results, the slabs design strength for this failure mode was determined according to the m e k method and partial interaction method.
