Abstract
The response of masonry arch bridges to moving wheel loads was simulated in the laboratory by constructing four half-scale arches with a span length of 1.22 m, using 17 voussoirs and lime mortar joints. The moving loads varied from 115 kg to 910 kg and were simulated by hanging steel weights from the center-of-gravity of the voussoirs. The finite element program ADINA was used to model the arch ring using 13,312 8-node isoparametric elements. Experimental results show the lime mortar joints exhibit significant plastic deformation accumulations with the first few cycles of loading, then diminish during subsequent load cycles. When the Drucker-Prager material model is used for the lime mortar, the FEM results indicate the plastic accumulations do not occur after the first load cycle. It is believed that sliding occurs between the voussoirs and the mortar, producing small cyclical deformations under moving loads. The four arches were also monotonically loaded to collapse in the laboratory, and the FEM stress variations normal to the mortar joints are illustrated for this loading condition.
