A Proposed Equation for the Evaluation of the Nominal Ultimate Bending Moment Capacity of Rectangular Singly Reinforced RPC Sections


Based on compressive stress – compressive strain curves of Reactive PowderConcrete (RPC) which have been established recently in a Ph.D thesis(1), anequivalent bi-linear compressive stress block for RPC sections under purebending moment is proposed and used to derive an equation for calculating thenominal ultimate bending moment capacity (Mn) of rectangular singly reinforcedRPC sections. The accuracy of the derived equation of Mn is examined bycomparison with the results of existing experimental tests.
