Arch dams have delicate sections thanks to their curvature. The fact that these are large, costly and construction takes many years increases the importance of structure. Mistakes / or accidents may occur during such structures major loss life property. Considering volumes, masses slenderness arch dams, they can be significantly affected by dynamic forces as changing water pressure, temperature...

The effect of frequency content on the dynamic response of concrete gravity dams is investigated in this paper. Dams are one of the most complex structures to handle when there is dynamic analysis involved. One of the influential parameters on these structureschr('39') seismic response is the frequency content of the earthquakes. An index to represent frequency content, which represents frequen...

Reinforced concrete structures used in many areas of our daily life constitute an important part the building stock construction sector. There are buildings such as reinforced buildings, bridges, tunnels, mosques and dams, new line with need continues. Many uncertainty factors play a role design phase these from dimensioning result analysis performed under required loadings to implementation fi...

Interfaces between two different mixes or strengths of concrete appear in large concrete structures involving mass concreting such as dams, nuclear containment vessels, cooling towers etc., since joints between successive lifts are inevitable. These joints and interfaces are potential sites for crack formation, leading to weakening of mechanical strength and subsequent failure. Research involvi...

In the present study, as a promotion to the previous attempt of the authors and his co-workers, Labibzadeh et. al. [1] the degradation of mass concrete of the Dez dam was evaluated in more detail using a more sophisticated numerical degradation model. In that preceding work, it was demonstrated that the concrete of the Dez dam has been deteriorated and its mechanical properties have been change...
