“…They allow estimating masonry elastic properties because of the relationship between the sonic wave velocity propagating through the material and its elastic mechanical properties (Everett 2013). The validity of the test has been widely demonstrated through onsite and laboratory works (Miranda et al 2012;Miranda et al 2016;Maccarini et al 2019;Murano et al 2019;Sánchez-Aparicio et al 2019). Even if specific standards to follow for sonic tests on masonry structures do not exist, the procedure is based on the same physical principles as the ultrasonic pulse velocity method developed for testing concrete, which adopts a procedure well-established by international standards (ASTM C597-09 2009; CEN12504-04 2004).…”

Structural assessment and seismic vulnerability of ancient masonry buildings is a difficult task even when employing advanced specialized technical skills, which requires a complex study. This paper aims to assess the structural and seismic safety of the Esfahan Shah Mosque in Iran by numerically investigating the nonlinear behavior of the mosque for different scenarios and identify if there is a correlation between crack patterns resulting from numerical analysis, inspection and historical evidence. Firstly, the numerical model of mosque is developed and updated using the experimental parameters obtained from a non-destructive test (NDT) campaign that included ambient vibration and sonic testing. Secondly, the FE calibrated model is used to evaluate the structural behavior of the mosque under vertical loading, including the influence of the soil and a sensitivity analysis varying the masonry material properties. Besides, the paper discusses the structural behavior

“…Figures 16 and 17 show the variation of equivalent viscous damping and cumulative energy dissipated for different displacement levels, and Table 4 shows the variation of cumulative energy of specimens after the test. The equivalent viscous damping (βeq) was estimated as per the recommendations of ATC [31] and Hou et al [32], as given in Equations ( 1) and (2).…”

“…Different from other traditional masonry structures, the strength of the stone is far higher than that of the filling material in mortar joints. By combining experimental and analytical approaches, as well as field investigations of earthquake damage to stone structures, it has been found that the mortar joint of a stone wall is the weakest zone under earthquake [1,2]. Despite past literature having developed different strengthening options of stone masonry joints [3][4][5][6][7][8], the seismic behavior has not yet been assessed.…”

“…Despite past literature having developed different strengthening options of stone masonry joints [3][4][5][6][7][8], the seismic behavior has not yet been assessed. Due to the diversity of masonry technology, the complexity of mortar joint composition, and the difference in material properties, the seismic behavior of stone mortar joints is more complex than that of common masonry mortar joints [2,9]. Therefore, understanding the seismic behavior of stone masonry is of great significance to further protective repair and seismic damage assessments of stone structures.…”

Seismic Behavior of Stone Masonry Joints with ECC as a Filling Material

et al. 2021

This paper investigates the seismic behavior of novel stone masonry joints using ductile engineered cementitious composite (ECC) as a substitute for ordinary mortar. Ten stone masonry joints with different types of mortar/ECC were tested under axial and cyclic loads. The filling materials of mortar joints tested included ordinary mortar, polymer mortar, ECC, and composite mortar with two combination proportions of ECC and ordinary mortar. The test results indicated that ECC specimens exhibited a more stable hysteretic response as well as an improvement in strength, deformation, energy dissipation, and strength degradation. The ECC mortar joints maintained integrity during the entire loading process due to the “self-confinement” effect of ECC. A partial substitution of mortar with ECC could provide effective reinforcement and confinement to prevent mortar failure and peeling, thereby allowing such specimens to approach the seismic performance of ECC specimens. Based on the trend of shear strength variations, a corresponding failure process is defined for ECC/mortar joints under cyclic and axial compressive loads, including four distinct stages: linear elastic, crack-developing stage, interface debonding, and friction sliding. New equations are proposed for predicting the shear strength and residual shear strength of the ECC/mortar joints on the basis of the test results, which are validated in the composite mortar specimens.

“…From an experimental standpoint, several works investigating tests aimed at understanding the load-bearing capacity of masonry vaults or structures in-and out-of-plane loaded through the application of incremental horizontal and vertical loads have been proposed in the technical literature [32][33][34][35][36][37]. In other papers [38][39][40][41], the dynamic response of masonry is inspected by means of tests carried out on shaking tables using in-scale models.…”
