Abstract

Among the several safety checks that must be performed during the design of small to medium single span railway viaducts, the one concerning vertical accelerations is often crucial for high speed railways, since under these conditions resonance is much likely to occur. Recent results [1]-[3] of several field measurements carried out on simply supported medium span concrete railway viaducts showed that the non-linear behaviour of the superstructure composed by ballast and rails can play an important role in the dynamic behaviour of the structure and consequent evaluation of its maximum vertical accelerations. The conclusions drawn from those measurement results pointed out that the superstructure must be taken into account in the numeric analysis of small to medium span bridges, mainly what global ballast-structure damping is concerned. This revealed to be particularly important when decisions are to be taken, related to the strengthening of existing structures in order to increase traffic speeds and when comfort of passengers is an important issue. In order to evaluate the vertical vibrations of the bridges when the dynamic behaviour of the track is taken into account, same authors have already proposed different models including vertical springs, dampers and masses, which are interpose between loads and structure in order to simulate the railway track behaviour. These models include the rail with flexural stiffness in vertical and lateral direction and axial stiffness in longitudinal directions, the rail pads as vertical springs and dampers, the sleepers as rigid bodies with masses, and finally the ballast as springs and dampers. The main purpose of this paper is to compare the dynamic behaviour of ballasted simple supported viaducts with and without the referred track models, taking into account the structural dynamic response obtained from the field measurements, in order to evaluate the influence of the track in the safety check. Furthermore, the response acceleration of the ballasted simple supported viaducts is also compared with the results obtained from the simplified methods proposed by the ERRI D214 Committee used to estimated the maximum acceleration at mid-span of simply supported bridges decks, namely the DER Method (Decomposition of Excitation at Resonance Method) and the Virtual Influence Line Method.
