Abstract

© 2019, International Masonry Society. All rights reserved.This paper investigates the mechanical behaviour of skew masonry arch bridges taking into account the arch ring-backfill interaction. A numerical model has been developed using the three-dimensional computational software 3DEC, based on the Discrete Element Method of analysis. Each brick of the masonry skew arch was represented as a distinct block. Mortar joints were represented as zero thickness interfaces which can open and close depending on the magnitude and direction of the stresses applied to them. The variables investigated were the construction method, the angle of skew and the critical location of the live load along the span of the arch. For each masonry skew arch, a full width vertical line load was applied incrementally until collapse. Failure modes and the ultimate load carrying capacity were obtained.
