Experimental and numerical characterization of the interface between concrete masonry block and mortar

Abstract

Masonry is a construction system that has been used since the beginning of civilization and is still used throughout the world. The finite element method is a recent development that allows complex problems, including structural masonry problems, to be solved. A vast amount of literature exists on finite element modeling, using software such as ABAQUS, to represent experimental masonry models. Based on this established pattern, an experimental and analytical research program was designed and implemented. Thus, a set of tests was conducted to determine the compressive and tensile strengths of the masonry components, i.e., block, mortar, and grout. Bond wrench tests, diagonal tension tests, and horizontal joint shear tests were conducted to characterize the interface between the blocks and the mortar. A finite element model was then developed to represent the physical models and the general conclusion is that the finite element model was able to represent reasonably well the physical models.

Computational modeling of structural masonry shear walls considering cracking effects at mortar joints

“…The tests results showed that this coefficient did not have much influence. Therefore, based on recommendations from Canadian Standards Association (S304-14) [23] and the studies of Parsekian et al [3] and Pasquantonio et al [24], the authors decided to adopt 1.0 as the value of the friction coefficient. In their work, Pasquantonio et al [24] presents a table with five other references about the coefficient of friction at the interface between masonry and mortar.…”

The average value of the coefficient of friction (μ) founded by those researchers was equal to 1.07, while the value of 0.61 was obtained by Pasquantonio et al [24] in the experiments carried out in their research.…”

A Simple Benchmark to Evaluate the Influence Parameters of the Microstructure of the Masonry Wall on Capillary Water Migration Dynamic

“…Masonry is a construction system that has been widely used since the beginning of civilization and is still used throughout the world [1]. Building materials and those cementatious are the most used for the construction of structures.…”

Experimental Study of Adobe Masonry and its Adherence with Reinforced Concrete Confinement Elements

“…Adherence is one of the most important physical properties in hardened glue mortars with variable and unpredictable responses, with aspects that have to be addressed such as resistance, adherence degree and durability [6]; these same standards refer to others that must be followed to measure adherence, but that does not relate this for concrete with adobe, there are few studies in this regard, being able to take as a reference experiment carried out with mud mortar in union of adobe pieces with an average shear stress of 0.038 Mpa [7]; or in the union of cement blocks with cement-sand mortar [8].…”
