摘要

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