| Abstract: | The shear lag effect of concrete box beam bridge in cantilever construction stage is serious,which need be considered especially.Shear lag effect of Xinjiang Yilite Bridge is discussed.The shear lag coefficients of the main controlling cross sections of the bridge are analyzed by using three rod analogous procedure and finite element method.The results are compared with measured stress data on site in construction stage.Thus it provides an important basis for analyzing shear lag effect of bridges which can'... |
