Research on the Experimental and the Testing Mode of Highway Bridge Load Capacity based on Static Analysis

Abstract

In this paper, we conduct research on the experimental and the testing mode of the highway bridge load capacity based on the static analysis. Modal parameters is refers to the bridge structure calculation of modal frequencies and mode shapes and modal parameters such as the quality. Modal parameters method and other methods differed from the load transverse distribution influence line is composed of the modal parameters are calculated out as every piece of beam deflection; Secondly, according to the modal flexibility from the deformation of beams in the mid-span position of value, according to the deformation value and beam on the number of slices, calculation, draw the influence line of transverse distribution of load. Under this guidance, we enhance the traditional methodologies with the static analysis that will achieve better performance.
