Ian Gilbert1 Abstract:The tensilapacityof concreteisusuallyneglectedwhen calculatintghe strength of a reinforced concrete beam or slab, even though concrete continues to c tensilestressbetween the cracks due to the transferof forcesfrom the tensile reinforcement te concrete through bond. ributionf the tensile concrete is known astension stiffenainndg it affe member’s stiffness after cracking and hence the deflection of the member and the width of the cracks under service loads. For l reinforced members, such as floor slabs, the flexural stiffness of a fully cracked many times smaller than that of an uncracked section, and tension stiffening contri greatly to the postcracking stiffness. In this paper, the approaches to account for stiffening in the ACI, European, and British codes are evaluated critically and pre are compared with experimental observations. Finally, recommendations are included modeling tension stiffening in the design of reinforced concrete floor slabs for de control.
