In this report we described on a leading of the load-deflection curve equation applicable to the restrained orthotropic reinforced concrete square slabs, and compared the curve of calculated results obtained from the equation with the curve of experimental values, then investigated. The load-deflection curve equation was obtained by the deformation-assumption of two stage as follow : The first stage curve equation was obtained by considering the bended like deflection on the slab's center line. The range use of the curve equation is from zero load to transverse tension crack load. The second stage curve equation was obtained by assumption the rigid zone as follow I It considered that the rigid zone spreads in from the center line of slab toward yieldline of bending with the increasing of center's deflection. The range use of the curve equation is from transverse tension crack load to ultimate load. Then, it considered that membrane force occured in position beyond transverse tension crack moment in the interior of slab. The result that the curve calculated values showed a fairly good approximate tendency of the curve experimental values found.
