Abstract:
The appearance of modulus of elasticity of concrete in the denominator of deflection formulas for reinforced and prestressed concrete structures, and the adverse effect of creep on deflections have convincingly hinted engineers to seek a concrete of high Ec and low creep to minimize deflections.
