摘要 本文探讨了钢筋混凝土简支梁桥支座的抗震计算方法,分析了支座在地震时的受力机制.通过算例给出了支座的水平地震力、竖向地震力,并探讨了支座上跳的可能性,为支座的抗震计算提供了理论根据. The method of aseismatic design for bearings of simply supported reinforced concrete bridges as well as the load carrying mechanism of the bearings during earthquake are discussed. With the help of analyzing numerical exam ples, the horizontal and the vertical seismic forces are presented, and the possibility of bearing-jumping is studied.It provides a theoretical evidence for the aseismic design of bridge bearings.
