Multivariate fatigue analysis for suspender of highway-railway combined bridge

WU Jun1,GUO Wen-hua2 (1.Guizhou Communication Planning Survey & Design Academy Co.,Ltd,Guiyang 550001,China; 2.School of Civil Engineering Central South University,Changsha 410075,China)  
Based on the fatigue analysis method of suspender,taking the highway-railway combined arch bridge as study objective,the special finite element model of the bridge was established by finite element program to calculate the fatigue of its suspender,and the fatigue effects of less than 30kN load of motor vehicles,lane distribution,load spectral type,and operating period on the suspender were analyzed.The results show that the less than 30kN load of motor vehicles have some impact on the fatigue of the suspender;the short suspender is easier to destroy in design reference period;the influence of light rail vehicle traffic on the boom is larger than the car traffic;the results,which are obtained by fatigue analysis of the suspender with different load spectrals,are differentiated;the fatigue damage of the suspender does not occur in design reference period under cyclic loading of the cars and light rail vehicles.
