| Abstract: | In this paper the responses of a simply supported reinforced concrete bridge to horizontal earthquake excitation are analysed. Effects of frictional force at movable supports on internal force of bridge piers and relative displacement between bridge piers and girders are presented. Earthquake loads of fixed bearings under conditions of different seismic coefficients and frictional factors are also investigated. An analytic model including effects of frictional force at movable supports is suggested. |
