Study of the longitudinal failure pattern of long span suspension bridges under earthquake

Nie Liying Zhang Lei Li Shuojiao (Hohai University,Nanjing 210098,China)  
Research on structural failure patterns forms the basis for structures to survive serious earthquakes.However,study of the failure patterns of long span suspension bridges under earthquake is rarely seen in the literature.For long span suspension bridges in China,the suspension part,consisting of main cables,stiffening girds and hanger ropes,is usually made of steel,and the pylon towers,as the core structural support components,are usually composed of reinforced concrete frames.Therefore,the focus of the study on the failure patterns of long span suspension bridges is on the reinforced concrete pylon towers.The longitudinal failure pattern and corresponding characteristics of long span suspension bridges under earthquake are investigated through finite element analysis with the Runyang long span suspension bridge as the example.The failure pattern is found to be in the form of synchronal double plastic-hinges.This implies that such mechanism in which the plastic hinges generate successively does not exist.Hence,whether or not the stiffness,after yielding of the pylon towers,can be used just like short or middle span reinforced concrete bridge depends on the structure's plastic buckling behavior under earthquake.
