In this paper, a graph theoretical method is used to introduce three basic operations of con guration processing; rotation, translation and re ection. The relationships between translation and rotation, and re ection ...

One of the sources of disturbance at intakes is the occurrence of free-surface vortices with an air core. The most common solution for avoiding air-entrainment is the use of anti-vortex devices and, especially, plates ...

Corrosion of steel structures is a serious problem throughout the world. The most signi cant consequence of corrosion is reduction of the section size. This, in turn, leads to a reduction in the carrying capacity and ...

Retaining walls may be constructed with an inclination angle of less than 90 from the horizontal axis. In the present study, using the horizontal slices method and limit equilibrium principles, in addition to assuming ...

Double Concave Friction Pendulum (DCFP) bearing is a new generation of friction isolator that contains two separate concave sliding surfaces with di erent properties. Accommodating enhanced performance, compared to the ...

In nonlinear static (pushover) methods of analysis as an alternative to time history analysis, the capacity curve of the structure is established with respect to the roof displacement. Disproportionate increases in the ...
