프리플렉스형의 피로거동에 관한 실험적 고찰 = An Experimental Studies on the Fatigue Behavior of Preflex Girder

다국어 초록 (Multilingual Abstract)

The studies are conducted to investigate the fatigue and fracture behavior of pre flex girder. In this work, the fatigue tests using by constant amplitude fatigue loading and 4-point-loading to maintain pure bending condition in the mid-span of preflex girder will be performed. It is expected from the results of the studies to provide the fatigue strength and the S-N curve of preflex girders. In addition, it will be ensured that fracture initiation occurs in the welded part of horseshoe-type shear connector as well as in other welded joints.
