Since GNSS is a three-dimensional satellite positioning and navigation system, however, it is unusual to monitor dams in the altimetric component with this system, but only in the two horizontal components. Thus, the third ...

For the safety assessment of concrete dam-foundation systems this study uses an explicit time-stepping small displacement algorithm, which simulates the hydromechanical interaction and considers the discrete representation ...

Visual inspection is a crucial task for the assessment of a dam conservation state. However, these tasks are time consuming and operator dependent, which leads to the aim of developing more objective procedures. Photographs ...

This study presents a robust contact constitutive model in the distinct element method (DEM) framework for simulating the mechanical behavior of masonry structures. The model is developed within the block-based modeling ...

The unreinforced masonry (URM) walls are the common load-bearing structural elements in most existing buildings, consisting of masonry units (bricks) and mortar joints. They indicate a highly nonlinear and complex behaviour ...

Discrete element block models provide a suitable tool for the numerical analysis of masonry structures, particularly apt to represent the nonlinear response governed by shearing and separation along the structure’s joints ...

Alkali-silica reaction (ASR) and delayed ettringite formation (DEF) are the most common internal swelling reactions (ISR) in concrete dams. The swelling effects and concrete deterioration caused by ISR can be observed in ...

Traditional dam safety methods, based on visual inspections and manual monitoring, have long been the standard for ensuring the stability and safety of dams. However, as the scale and complexity of dam projects have ...
