Abstract

Mechanical behavior of fiber reinforced concrete sleepers under dynamic loading, whose track structure is modeled by Finite Element Method, is presented in this paper. For, the Serendipity bi-dimensional finite element is used. The implicit Newmark method is used for numerical solutions of the track structure motion equation. The railway concrete sleepers are loaded by the rails and railroad tracks loads. The response function for time-domain is used for appropriated choosing of the type and volume fiber in order to reduce vibration amplitude of the track structure. The weight of the reinforced railway sleeper reinforced is also evaluated since it interfers on manufacturing and transport costs. It was observed that carbon and aramid fibers are those which
most contribute for reducing vibration amplitude and sleeper railways weight.
