Experimental study on the rigidity behavior of Prestressed Steel Reinforced Concrete beams

Prestressed Steel Reinforced Concrete (PSRC) Structure is a new system by combining PC technology and steel reinforced concrete (SRC) structure, and is a technical innovation to the conventional structures, such as concrete structures, PC structures and SRC structures. Because having much virtue, for instance high bearing capacity, fine serviceable performance, covering and over loading capability, it will have expansive application. The serviceable performance can be observably improved by putting PC technology on the SRC beams, such as rigidity and crack resistibility degree. Based on static loading experiments of seven PSRC beams with different designing coefficients, the experimental phenomena as loading process, failure pattern are studied, and the primarily influencing factors on fiexural performance have been contrasted to educe conclusion for future design.
