Ravathi Journal on Civil Engineering 2249 - 0779 1 3 1 6 Prefabricated Cage, Load – Deflection Response, PCRC Beams, Effective Moment of Inertia Experimental studies have reported that Prefabricated Cage can effectively improve the flexural strength, ductility and deformation characteristics of Prefabricated Cage Reinforced Composite (PCRC) Beams. This paper presents an analytical solution to predict the load deflection response of PCRC beams. An equation for effective moment of inertia is proposed interms of uncracked and cracked moment of inertia of the section. A reduction factor Beta is also introduced in the equation to account the influence of percentage of steel and yield strength of steel. Experimental results from literature were employed to validate the analytical results. The findings show that the theoretical analyses are in good agreement with the test data in load–deformation curves upto yielding of steel. The theoretical deflection calculated at service load has a reasonably good agreement with the experimental results, which demonstrates the present closedform solution is simple yet accurate. The analyses also show the deformation characteristics of PCRC beams is significantly influenced by the percentage of tension steel. June - August 2011 Copyright © 2011 i-manager publications.
