Considering the vertical- and lateral-effects to RC buildings are exposed, type of construction andgeometrical properties of the bearing members is known as the effective parameters in the structuralbehavior. Slabs defined the bearing members are plane members that transfer the acting loads to the columnsand beams. RC slabs are generally classified as beam slab, flat slab and ribbed slab according to the way oftransferring the loads in RC buildings under seismic effects. Especially in housing types, ribbed slab systemis preferred, while parking type structures are used flat slab system. In this choice, the function of thestructure is taken into consideration, and the effect of the selected slab type on the seismic behavior ofstructures can be ignored. In this respect, the structural behavior of the slab types on the structural behaviormust be investigated, extensively. The aim of this study is to examine the effects of slab type on structuralbehavior in a low-rise RC building. Within the scope of the study, three-dimensional structural model of theexamined building is prepared by considering three different slab types, and then analyzed by using linearand nonlinear-analysis methods such as equivalent earthquake load-, mode superposition- and time historyanalysis-method. As a result of numerical analysis, the parameters that are effective in the structural behaviorand construction process – seismic performance, torsional behavior, story drift, etc.– are compared andevaluated the parameters in the selection of slab type in low-rise buildings. Consequently, suggestions fordetermining the most suitable slab system for the low-rise buildings presented.
