Abstract

For evaluating seismic resistance of railway transfer overbridges constructed with reused aged rails, we investigate the deformation properties and M-φ relationships of axially loaded aged rail columns by conducting cyclic loading tests. Using four kinds of different aged rails of the product year (1888, 1895, 1922 and 1925) and different product countries, we perform forced deformation bending test around both of weak and strong axes for each aged rail columns. As the results of this experimental study, we obtain hysteresis curves and M-φ relationships which is available for practical use of evaluating seismic performance. In this manner, it is possible to evaluate the ductility of aged rail columns accurately.
