Pseudo‐dynamic testing of a concrete gravity dam
Earthquake Engineering & Structural Dynamics, 2015 SummaryInspired from the simplified single degree of freedom modeling approach used in the preliminary design of concrete gravity dams, a pseudo‐dynamic testing method was devised for the seismic testing of a concrete gravity dam section. The test specimen was a 1/75 scaled section of the 120‐m‐high monolith of the Melen Dam, one of the highest ...

The cohesive frictional crack model applied to the analysis of the dam-foundation joint [PDF]
, 2010 The mechanical behaviour of dam-foundation joints plays a key role in concrete dam engineering since it is the weakest part of the structure and therefore the evolutionary crack process occurring along this joint determines the global load-bearing ...

Modal Analysis of Chushandian Gravity Dam
Journal of Engineering Research and Reports, 2023 This article uses the finite element software ABAQUS to establish a three-dimensional finite element model based on the overflow dam section 12 # ~15 # and surface outlet dam section of the Chushandian gravity dam. The stress and displacement distribution of the 12 # ~15 # dam section of the Chushandian gravity dam under normal water storage level are ...
