Ductility of externally prestressed continuous concrete beams
KSCE Journal of Civil Engineering, 2014 Ductility is a desirable structural property that allows stress redistribution and provides warning of impending failure. Factors affect the ductility of beams prestressed with external FRP tendons are different than those affect the ductility of ordinary bonded prestressed concrete beams due to lack of bond and linear stress-strain relationship of FRP

Strength and Ductility of Concrete Encased Composite Beams
Engineering and Technology Journal, 2012 Experimental research was conducted to investigate the structural behavior of concrete-encased composite beams. Specimens were tested under lateral loading. The test results indicate that the behavior and failure mode of the beam are greatly affected by the steel beam core. The beams showed highly ductile behavior.

Flexural Strength And Ductility Improvement Of Nsc Beams
, 2011 In order to calculate the flexural strength of normal-strength concrete (NSC) beams, the nonlinear actual concrete stress distribution within the compression zone is normally replaced by an equivalent rectangular stress block, with two coefficients of α and β to regulate the intensity and depth of the equivalent stress respectively.
