Title

CONTROL SEISMIC LOAD USING ENERGY DISSIPATION IN STRUCTURES

Abstract

Seismic waves are waves of energy that travel through the Earth's layers, and are a result of earthquakes, volcanic eruptions, magma movement, large landslides and large man made explosions that give out low-frequency acoustic energy. Many other natural and anthropogenic sources create low-amplitude waves commonly referred to as ambient vibrations. Earthquakes create distinct types of waves with different velocities; when reaching seismic observatories, their different travel times help scientists to locate the source of the hypocenter. When earthquakes occur, a building undergoes dynamic motion. This is because the building is subjected to inertia forces that act in opposite direction to the acceleration of earthquake excitations. These inertia forces, called seismic loads, are usually dealt with by assuming forces external to the building. The determination of seismic risk is the foundation for risk mitigation decision-making, a key step in risk management. Large corporations and other enterprises (e.g., local governments) analyze their 'portfolio' of properties, to determine how to best allocate limited funds for structural strengthening of buildings, or other risk reduction measures such as emergency planning. In calculating the risk of each facility in the 'portfolio', potential life safety and economic losses due not only to structural damage, but also to equipment, contents and business interruption are considered. Damper amplification factor and its optimum parameters are used in this method to achieve the goal and fulfill the identified requirements. The energy dissipation systems are devices specially designed and tested to dissipate large quantities of energy. The most common energy dissipation systems are the viscous ones (force proportional to the velocity of deformation) and the hysterics (force proportional to displacement), however there are also the viscoelastic, electro-inductive and by friction damping systems. Viscous dampers devices consist of a cylinder containing a high viscosity fluid. This operation is simple: during an earthquake, the force generated by the imposed acceleration is transmitted to the damper, which regulates the passage of compressed fluid through small holes. The seismic energy is dissipated, as fast as the liquid flows through the holes.
