The effect of intelligent semi-active thermal exchange-fuzzy controller in structural rehabilitation by attenuating seismic responses of structural systems is investigated. In the suggested control system, MR dampers and sensors are employed as a semi-active controller. Resultant control forces of MR damper are administrated by providing external voltage supply, during the earthquakes and high ...

This is a small pattern language for running online trainings. The language starts with an entry pattern ONLINE TRAINING. All other patterns are supporting this pattern and help to make online trainings more alive. Some of the patterns are not exclusive for online uses, for instance PREPARED EXAMPLE or TEST RUN. These patterns could be part of a pattern language for trainings as well. They are ...

In recent years, destructive earthquakes have shown the deficiencies of the existing buildings. One of the most effective mechanisms for dissipating the earthquake energy is inelastic deformation of the steel components. The objective of this research is to study the application of metallic dampers for dissipation of the earthquake energy and to investigate the behavior of concrete structures i...

This research examines dynamics and change in the Iranian family during the recent half- century especially subsequent to the Islamic revolution in 1979. Developmental positions and changes are discussed and consideration is given to the extent to which family dynamics and change have been influenced by structural changes or ideational forces. We will focus on ideational forces based on a new a...

Structural vibration control is one of the most important features in structural engineering. Real-time information about seismic resultant forces is required for deciding module of intelligent control systems. Evaluation of lateral forces during an earthquake is a complicated problem considering uncertainties of gravity loads amount and distribution and earthquake characteristics. An artificia...

The dynamic nature of loads, seasonal variation of soil properties, uneven soil strata below footings or inappropriate design of foundation makes differential settlement inevitable. Differential settlement is largely responsible for developing forces or changing the existing forces in the structure and is often considered as the underlying cause of many structural failures. A structural enginee...
