Abstract:
To study the shear lag effect in cable-stayed bridge with П-shaped cross section, a parametric analysis using finite element analysis was carried out, in which the parameters, such as prestress, transverse slope of bridge deck and little longitudinal beams were considered. The credibility of the finite element model was validated by comparison of its results with the test results of the bridge. The results indicate that the prestress has much effect on the shear lag, and it should not be neglected during calculation. Transverse slope is another important factor to influence the shear lag effect, especially influence the longitudinal normal stress near the middle area of the deck. It also shows that adding longitudinal girders can improve the stress distribution obviously.
