Structural Behavior Of Pier Columns On Small-Medium Span Skew Girder Bridge

In the process of bridge design, Sometimes it is unavoidable that design Skew GirderBridge and different high pier columns effects by topographical and geological hydrological.Itis less for the skew girder bridge design research relative to straight bridge at home andabroad，especially for the infrastructure.Engineers have of great freedom during the designing,because the girder bridge design codes and technology research materials are not too much forthe special structure.For different angle skew girder bridge and different height of pier, thechange of mining in different lane when loading the stress of the pier, it has importantapplication in actual engineering design value to further research these questions.This paper is based on Reinforced Concrete and Prestressed Concrete Highway BridgeDesign Code (JTG D62-2004) and relevant bridge pier stress analysis of some theories，combined with the engineering practice using the bridge special software of Mdias Civil,withHighway Bridge Design General Rules(JTG the D60-2004) about loading method of themoving load, and uses two different lane loading method (eccentric and symmetric). withvarying two different parameters of degrees and height,which consider zero degrees、 fifteendegrees、thirty degrees、forty-five degrees、sixty degrees and pier height of five meters、sevenmeters、nine meters、eleven meters、 thirteen meters、fifteen meters, this paper analyzes thechanging trend of moment and torque of the pier, which build in skew beam bridge. On theone hand, this paper discuss about the influence brought by the height ofDouble-Limb-Connected Pier ranging over two meters, three meters, four meters, five metersand six meters on the torque of pier, on the other hand analyze how obliquity effect on theanti-push rigidity and displacement on the top of the pier. With further research and discussion,the conclusion of this kind of bridge has reference value on the future designs.
