Reinforcement calculation

Bending reinforcement design of rectangular slab with TORAYCA® laminate (allowable stress design)

Select the TORAYCA® thickness to be adopted and fill out the required fields (blue). When the reinforcement calculation button is pressed, calculation will be performed and the result will be displayed.
Caution: This calculation sheet should be used at the responsibility of the user.
