Historical masonry structures made from locally available materials such as stone, brick, and mud are an integral part of our cultural identity. Moisture content is a critical environmental factor that can significantly impact the durability strength these structures. ingress in cause detrimental effects decreased strength, increased porosity, reduced bond between mortar units. Understanding th...

Francisco Conde-Valvís’s so-called “stone treasure” is a set of unique carved stone pieces, such as bases, column shafts, mortar, and decorated fragments (trisqueles rosettes), found during the 2018 excavation campaign in Cibdá de Armea (Allariz, Ourense). They had been piled up re-buried—no records existed to where—at western end Finca A Atalaia, which was excavated 1950s under direction Conde...

The aim of this work is to take full advantage Spectral Element (SE) and Finite (FE) codes by setting up a SEM/FEM co-simulation strategy for soil structure interaction problems, involving SE code generate propagate elastic waves in the soil, while FE enables detailed representation studied structure. spatial coupling managed standard mortar approach, whereas time integration dealt with an hybr...

This paper presents the results of experimental studies on deformation and strength anisotropy gravel-pebble soils used in soil dams. During stabilometric tests, varying shear angles were obtained for stone at different orientations particles working chamber, whether horizontal or vertical. As hydrostatic pressure chamber increased to 0.8 MPa, a reduction by 8-12 degrees depending direction lay...

We present an image-based pipeline for generating geometrical digital twins (GDTs) of stone masonry elements with detail down to the level. For this purpose, we acquire RGB images individual stones and wall during construction phase. In our framework, use structure from motion (SfM) first generate 3D source destination models, which are then registered form GDT through non-linear least squares ...

This study used two types of Recycled Concrete Aggregates (RCAs) with the same original virgin aggregate, but with different amounts of residual mortars. To verify that the mechanical properties of the concrete were affected by changing the unit volume of residual mortar, fresh mortar, and total mortar of the concrete, a series of paving concrete mixes were made using a modified equivalent mort...

This article presents the research results on assessing strength of reservoir slope under influence different wind speeds. Calculating parameters wave effect dam Rezaksoi was carried out. The average height determined using existing calculation methods for Rezaksoy Reservoir. Stones sizes are used to strengthen and protect it from effects waves, stones with an diameter selected calculations. Ba...

As commonly used canal system structures, masonry arch aqueducts constitute a significant proportion of Chinese old irrigation infrastructures. Most these existing are well over 50 years old, the deterioration their constituent materials time, as development other defects, significantly affects mechanical responses structures. A deep understanding on dominant factors that influence structural s...
