摘要：The reliability analysis method of the existing overpass structure is proposed by considering uncertainties of parameters and the effects of friction force at movable supports. And the earthquake-resistant retrofit optimum ideas are presented for the existing overpass structure based on the structural reliability. The optimum ideas are employed to solve the problem of safety and economy by taking the existing overpass structure as the whole system. The practical analysis methods for the earthquake-resistant retrofit and the earthquake-resistant decision for practical overpass structure are built.
