Explain parasitic forces for pre-stressing
Explain parasitic forces for pre-stressing?
Expert
In the structures which are statically determinate, pre-stressing forces causes the concrete arrangements to bend upwards. Hence, pre-cambering is normally carried out to counteract such effect and make it more pleasant in looks. For statically undetermined structures the deformation of concrete members are restrained by the supports and consequently parasitic forces are developed by the pre-stressing force in addition to the bending moment generated by eccentricity of pre-stressing tendons. The developed forces at the support modify the reactions of concrete members subjected to external loads and produces secondary moments (or parasitic moments) in the structure.
