Abstract
In order to understand the structural stress characteristics of the cable clamp of super-span bridge,a super span suspension bridge was taken as an example,a certain characteristic cable clamp was selected as the re-search object,and a spatial finite element model was established.The stress state and stress distribution law of each component of the cable clamp structure were analyzed and studied,and compared with the current sus-pension bridge standard formula.The results showed that under the action of unfavorable load,the stress of each component of the cable clamp structure of the bridge met the requirements of the specification,and the stress transfer between the components was smooth.The circumferential tensile stress of the left and right half cable clamps along the wall thickness was in good agreement with the calculation results of the current suspen-sion bridge design specification formula.For the left-right type pin-connected cable clamp,the sling force had little effect on the contact pressure between the cable clamp and the main cable,and would not cause a large degree of cable clamp disengagement and screw unloading.关键词
