The damage to model concrete gravity dams subjected to water explosions
Defence Technology, 2023 Over the past century, the safety of dams has gradually attracted attention from all parties. Research on the dynamic response and damage evolution of dams under extreme loads is the basis of dam safety issues.

DAM MOVEMENT MODELING BY USING MULTIPLE LINEAR REGRESSION AND ARIMA MODELS [PDF]
Geodetski Glasnik, 2020 Structural health monitoring of the large infrastructural objects (high buildings, bridges, tunnels, dams, etc.) is in the domain of civil and geodetic engineers who use different methods and instruments for this task.

Sensitivity of 3D Base‐Isolated Buildings to Individual Isolator Variability
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Variability in elastomeric isolators arises from differences in rubber formulation and curing, leading to noticeable changes in stiffness and damping among nominally identical bearings. While most previous studies have examined global isolator variability associated with environmental or aging effects, individual isolator variability has ...

Predicting seismic damage on concrete gravity dams: a review
Structure and Infrastructure Engineering, 2022 The seismic assessment of concrete gravity dams is a problem of prediction of cracking and the corresponding consequences. With the widespread use of general-purpose finite element programs, the work in the field has shifted towards quantifying the behaviour in a framework for assessment.

Progressive Failure Research on Foundation Surface of Concrete Gravity Dam
, 2010 Concrete dam safety is one of the hot issues in dam study with the increasing of dam’s scale and height. Sliding failure along foundation surface is a potential failure mode of concrete gravity dam, and this mode is relatively rare in practical ...

Seismic Simulation and Base Sliding of Concrete Gravity Dams
, 2010 A simplified procedure to estimate possible base sliding of concrete gravity dams induced by an earthquake is proposed on the basis of results obtained by parametric analysis. A simple mechanical model is developed to take into account the most relevant parameters influencing seismic response such as dam-water and dam-foundation interaction.

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas
Sustainable Development, EarlyView.ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...
