Experimental Study on Dynamic Characteristics of Cable-Stayed Bridge

사장교의 동특성분석에 관한 실험적 연구

Recently, cable-supported long-span bridge are widely constructed due to improved quality of cable and development of design and construction techniques. In this study, an existing cable-stayed bridge, Dolsan Bridge, has been evaluated based on the cable forces measured using vibration method. And the finite element model using in this study for the dynamic analysis has been found to be quite comparable with dynamic mode shapes and natural frequencies estimated from experimental data induced by ambient traffic excitations.
