Enhancement Of Compression Zone Of Reinforced Concrete Section Due To Camber

An attempt is made to study the effect of camber on compression zone of reinforced concrete section at mid-span of a beam. This is done by deriving formulas (based on strain measurements) to calculate total compressive axial force and axial compressive stress acting on a concrete section of single and triple span portal frames with straight and cambered beams. Keywords: Camber, Strain, Stress, Total compressive axial force
