Numerical Model Calibration and a Parametric Study Based on the Out-Of-Plane Drift Capacity of Stone Masonry Walls

Failure under seismic action generally occurs in the form of out-of-plane collapses walls before reaching their in-plane strength historical stone masonry buildings. Consistent finite element (FE) macro modeling has emerged as a need for use assessments these walls. This paper presents numerical model calibration U-shaped multi-leaf wall specimens tested ambient vibrations and (OOP) load reversals. The uncertain elastic parameters were obtained by manual models based on vibration test (AVT) data specimens. To obtain nonlinear parameters, static pushover analyses performed FE simulating quasi-static tests. calibrated matched well with experimental results terms load–drift response damage distribution. As result, modulus elasticity tensile compressive degrading proposed. A parametric study was conducted to examine effects different materials geometric properties (tensile strength, aspect ratio, slenderness scale) OOP behavior quite strain distribution case large while it determined that scale had no effect Tensile dominant parameter affecting models. Within presented work, practical tool assessment been proposed structures covered this paper.
