Experimental Study of Pre-Stressed Concrete Beams with Fatigue Subjoining Freezing-Thawing Circle
Based on fatigue tests of pre-stressed concrete (PC) and ordinary concrete beams for 15 specimens after different times of freezing-thawing circle, the degradation process for the tested beams of the relative dynamic elastic modulus is conducted. The experimental study shows that the pre-stressing level and times of freezing-thawing circles are main influence factors to durability of test beams. The results of this study are useful for the exploration of the mechanism of the PC structure’s damage and the improvement of design theory concerning the durability of the PC structures.
