This report obtained the load-deflection curve to ultimate load of orthotropic reinforced concrete slabs and it compared the experimental values with calculated results then investigated. The load-deflection curve was obtained by dividing into three stages as follow. In the first stage curve is from zero load to transverse tension crack load. The curve was obtained by considering the bended like deflection on the slab's center line. In the second stage curve is from transverse tension crack load to Johansen's load. The method was obtained by assumption as follow. It considered to spread in rigid zone from the center line of slab towards yield-line of bending, and the member between both ends of rigid zone and both ends of slab considered to occur only member translation angle. In the third stage, the curve was obtained by considering to occur only rigid body turning of member which is between the vield line of bending. Then, it assumpted than membrane force occured in the interior of slab.
