【Abstract】 According to the steel bar’s characteristic in CRCP under vehicle load, orthogonal anisotropy membrane model is presented to analyze the stress of CRCP using finite element method. Through a great deal of calculation for different load position, two critical load positions are found out under the different transverse crack spacing. The influence of steel amount and steel bar distribution on the load stress is discussed.更多还原
