Abstract

Abstract

Based on the finite element model of cable for cable-stayed bridge,it was analyzed the influence of three environmental factors including damper,beam vibration and temperature upon the cable's vibration fundamental frequency when considering engineering parameters of cable. The results show that when the damper's installation position is fixed,the influence of the damper upon the long cable's fundamental frequency is greater than the influence upon the short cable's. When the cable's length and the damper's position are fixed,the influence of the damper upon the fundamental frequency of the cable which has large section diameter is less than the one has small section diameter. The fundamental frequency of the cable has dynamic fluctuations because of the cable-stayed bridge's beam vibration caused by the vehicle load. To make the fundamental frequency more accurate,the time with a few vehicles may be selected when measuring the cable force. Temperature variation also has influence upon the fundamental frequency of the cable. Namely,the higher of the cable's temperature,the smaller of the fundamental frequency; the lower of the cable's temperature,the bigger of the fundamental frequency.
