Abstract: An improved tension stiffening model is proposed for short-term deformational analysis of reinforced concrete flexural members. The model has been derived by utilising the direct and inverse analysis techniques with the use of layered approach of computation based on xperimental moment-curvature relationships of concrete beam specimens. For ease of implementation by structural designers, a simple formulation of tensile stress block with dependence on the reinforcement ratio has been established. The proposal has been v rified to have desirable accuracy. In addition to steel reinforced concrete beams, the analytical methodology has been applied to fibre-reinforced polymer (FRP) reinforced concrete beams.
