| Abstract: | The 33 6 meter-length prestressed concrete curved girder is applied in scene f rame of Dongli Park in Harbin.The following problems of this curved girder are a nalyzed:how to determine the material of the curved girder,the profile of prestr essing tendons;how to calculate external loads and internal forces;how to comput e areas of pretressing tendons and non-prestressing steel;how to control the cr ack and deflection of the girder.It may bea reference for design and constructio n of similar projects. |
