【 摘 要 】

In order to research the action of embedded steel tube on improving shear performance of concrete bridge piers, the transverse static load tests of one reinforced concrete pier and six steel tube reinforced concrete piers were conducted. Test results indicate that the failure patterns of piers were shear diagonal compression failure. The local failure of the bridge piers embedded steel tube skeleton were more integrity. On the basis of the equation of mechanical equilibrium, formulas for calculating the shear capacity of the composite pier were established by considering the modification. The calculation results agreed well with the test conclusions, which provides references of the application of steel tubes embedding in bridge piers for both researching and designing.
