The aim of this paper is to describe how ground-based radar interferometry can provide displacement measurements of earth dam surfaces and of vibration frequencies of its main concrete infrastructures. In many cases, dams were built many decades ago and, at that time, were not equipped with in situ sensors embedded in the structure when they were built. Earth dams have scattering properties sim...

The design of arch dams usually involves a prolonged process of successive trial and error redefinitions. The current computer technology however enables to automate this task, in order to achieve the most economic solution overall. In the paper, the implemented optimization method of the geometry of concrete arch dams is presented as well as case studies of its application in the design of two...

In this article, an analytical model is presented for the simulation of the thermal behavior of dams that are subjected to the environmental thermal action during service. The method of solution adopted as well as the evaluation of the different parameters is described in detail. Also, the theoretical results that are predicted by the model are compared with experimental results obtained throug...

Nowadays, Alkali Aggregate Reaction is considered as one of the most dangerous weak points of concrete and its occurrence has been widely reported in various structures. In the current study, a program is developed for predicting and examining the effects of mentioned reaction on the three-dimensional analysis of concrete structures such as arch dams. In this regard, a program provided for dam ...
