CONTROL OF VIBRATION THROUGH AN INNOVATIVE ISOLATION TECHNIQUE OF A MULTISTORY BUILDING USING MAGNETIC FIELD

Arjun Sil

Abstract: The paper presents a simple and an innovative idea regarding vibration isolation technique of a multistory building using magnetic field and is proposed to application in the field of civil engineering structures. This idea is fully based on hypothetical concept, but the objective is to explore this idea or concept in to the entire community which may be a potential sector for the effective vibration isolation system. The technique is described based on the magnetic properties of materials and a magnetic field characteristic which depends on the amount of current flow, number of turns in coil, distance between electromagnet and the magnetic materials. Therefore using magnetic field, the attraction induced between magnet and magnetic materials, a force could finally be developed on the floor of building. This force would become effective until and unless the power is cutoff. Therefore this induced force is actually acts as a live load on the structure which indirectly increases the weight and this has been described in this paper.
