Abstract

Prestressing steel has been popular in the recent past, due to the developments in the field of anti-corrosive coatings. The literature substantiates the application of technique of prestressing to steel structures both in safety and economy point of view. However, for all design calculations, the maximum allowable span for a given LOAD CARRYING CAPACITY is based on maximum DEFLECTION which is calculated by principle of SUPERPOSITION (considering the effect of prestress and total load individually). This paper proposes a method of arriving at expression for DEFLECTION of SIMPLY SUPPORTED, prestressed HOMOGENOUS steel I-beams calculated by considering the combined effect of prestressing and total load. A straight tendon configuration with an eccentric prestressing force is considered for study.
