Title: THE INTERACTION OF UNLOADED RAILS IN CALCULATING THE SUPPORTS OF POINTS AND SWITCHES
Abstract: When a train passes over the points at a turnout, all the rails cannot be under load at the same time. The unloaded rails resist the deformation of the rail support at the turnout under the load. This resistance acts as a reactive force on the switch support components. This problem is particularly important for the design of the reinforced concrete slab bases, because of the possible negative bending moments in the areas of parts weakened by the rail fasteners. The author gives some logic-mathematical models to provide a hypothesis and a calculation formula.
