Comparison of retrofit methods for mechanical systems based on their seismic behavior

Mechanical and electrical equipment such as structural components and architectural structures are susceptible to damage caused by the earthquake. Since the methods of installing such systems are limited, the risk of injury is high on this component. On the other hand most of the mechanical and electrical equipment for the project will not be built and developers can set their profile. The manufacturers are not familiar issues of design and safe seismic various cause damage to the system during past earthquakes has been. In this paper examines the damage to mechanical and electrical systems in recent earthquakes in various sources discussed and reached the conclusion that the failure of equipment, are connected rigidly to the ground or structures, mainly due to lack of strength or lack of ability components anchor attached to the equipment due to the relative displacement and the force of an earthquake is caused by the weight of the equipment and equipment that is installed on vibration isolators can also lead to a lot of damage. Each of these separations and their reactionary base must be able to withstand the forces exerted. Often in this type of system failure is due to lack of adequate control of reaction and separation based. Also examines to study. And comparison vulnerability reduction strategies in the mechanical and electrical systems that come in different sources which are described in detail below.
