This paper aims to analytically investigate the effects of cable rupture on the dynamic responses of concrete cable-stayed bridges. Analytical methods for simulating the cable rupture using a time history function have been examined and the dynamic amplification factor (DAF) is considered as a design criterion. The calculated DAFs from a concrete cable-stayed bridge were compared with those from a typical steel composite one. DAFs were calculated for member forces of the deck system and stay cables. The comparison verified that the current design guideline for DAF may be reliable in general sense but underestimate DAFs in some parts of concrete cable-stayed bridges. |
