Abstract
Unreinforced masonry structures are susceptible to man-made hazards such as impact and blast loading. However, the literature on this subject mainly focuses on masonry wall behavior, and there is a knowledge gap about the behavior of masonry arches under high-strain loading. In this context, this research aims to investigate both quasistatic and impact response of a dry-joint stone masonry arch using the discrete element method. Rigid blocks with noncohesive joint models are adopted to simulate dry-joint assemblages. First, the employed modeling strategy is validated utilizing the available experimental findings, and then sensitivity analyses are performed for both static and impact loading, considering the effect of joint friction angle, contact stiffness, and damping parameters. The outcomes of this research strengthen the existing knowledge in the literature regarding the computational modeling of masonry structures that are subjected to usual and extreme loading conditions. The results highlight that applied discontinuum-based numerical models are more sensitive to stiffness parameters in high-strain loading than static analysis.
Highlights
Masonry represents the most widespread construction technique worldwide with different load-bearing structural forms and is known as the oldest construction technique, which mankind has been using since the earliest times.Despite their widespread use, masonry structures are vulnerable to hazards

This study aims to investigate both quasistatic and impact response of a single span stone masonry arch using DEM, which falls into the category of simplified micromodeling
Summary
Masonry represents the most widespread construction technique worldwide with different load-bearing structural forms (arches, domes, piers, etc.) and is known as the oldest construction technique, which mankind has been using since the earliest times. Proposed a dynamic interface model and implemented into a commercial finite element code to capture high strain rate effects on the unreinforced masonry walls subjected to lowvelocity impacts. Burnett et al [8] used deformable solid elements in FEA and formulated contact models for masonry joints to capture nonlinear effects These FEAbased simulations were performed using different commercial FE software packages (e.g., ABAQUS, ANSYS, etc.), but researchers developed different modeling strategies using noncommercial codes. Their study is a rare example of research investigating the blast behavior of curved masonry structures, vaults, using the discrete element method (DEM). Arches form the basis of more complex elements such as vaults and domes Their response to impact and blast loading is crucial to prevent catastrophic local and global damage and total collapse of structures. The effect bond properties were explored through the proposed computational models in light of the results given in the reference study
