Factors influencing the deflection of PSC beams

FACTORS INFLUENCING DEFLECTIONS:

The deflections of prestressed concrete members are influenced byy the following salient factors:

·        Imposed load and self weight

·       Magnitude of the prestressing force

·       Cable profile

·       Second moment of area of cross section

·       Modulus of elasticity of concrete

·       Shrinkage, creep and relaxation of steel stress

·       Span of the member

·       Fixity conditions
