Abstract
Masonry arches are vulnerable to seismic actions. Over the last few years, extensive research has been carried out to develop strategies and methods for their strengthening. However, from such studies, it became evident that the application of reinforcement in a masonry arch is done in such a manner that the failure of the system is transformed directly from one of stability to strength. This direct transformation overlooks the intermittent stages that exist between stability and strength, and thus provides an incomplete picture to the potential behaviors of the system. This study aims to investigate the non-linear dynamic behavior of masonry arches subjected to hinge control through the two-dimensional Discrete Element Method (DEM) based software UDEC. Within the DEM, each voussoir of the arch was represented by a distinct block. Mortar joints were modelled as zero thickness interfaces which can open and close depending on the magnitude and direction of the stresses applied to them. Twenty-five unique configurations of an arch with controlled hinges were developed and their behavior to different ground shaking motions is discussed. From the results of this analysis, it is evident that controlling the hinges of a masonry arch creates the potential to both increase capacity and define failure for dynamic loading conditions.
