PSC-I 거더의 균열 발생 이후의 휨거동에 관한 실험적 연구
Am Experimental Study on the Flexural Behavior after Crack Initiation of PSC I-Girder
초록
The main objective of this study is to develope the PSC-I girder for long span bridge. This study investigates the structural behavior of Postcracking stage and efficiency of proposed PSC-I girder using 1/2 scaled prototype beam specimen. Three specimens are tested under three point static loading system. Ideally, the Load-displacement relationship is trilinear. The crack patterns and failure mode of each specimen are reported in this paper and they are compared to each other with ductility and strength.
