In this paper, the seismic failure mechanisms of the two-story masonry structure are investigated by combining structural health monitoring data obtained using digital accelerometers and numerical simulation results. In situ measurements were performed to record ground motions simultaneously at various locations and the associated response of the structure at the critical regions of the walls. The measured acceleration signals were filtered, baseline corrected, and Fourier transformed for the analysis of the dynamic characteristics and response damage-sensitivity factors in the frequency domain. For the numerical simulation, a three-dimensional finite element model of the masonry structure was built using the ANSYS software package, and nonlinear time-history analyses were carried out using scaled ground motions obtained from field measurements. The results obtained from the numerical simulation, including modal data, acceleration amplification, displacement demand, stress and shear magnitude, and force-displacement curve, were compared and validated against the results obtained from field measurements, providing a combined approach to reveal the critical failure mechanisms, including the shear cracking of the walls, stress concentration areas, and gradual stiffness reduction due to increased seismic load intensity. From the results, it can be concluded that digital accelerometry-based SHM techniques can provide physically consistent and case-specific insights into the seismic response of the investigated masonry structure for inferring the seismic response and failure processes associated with masonry structures. In view of the results, the integrated field SHM and numerical technique can accurately interpret the observed damage and describe the associated seismic failure processes of existing masonry structures.
