Factors influencing the deflection of PSC beams

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


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
