Study of Behavior of Plan & Vertical Irregularity by Seismic Analysis

Numerous attempts on research and development for anti seismic structures or the structures that can withstand seismic hazards and lend some ground resistance in earthquakes haven’t yielded any satisfactory conclusions. Even though after decades of study and implementation of advanced designing, execution and maintenance tactics in high rise structures, many construction aspects have found a new ways to deal with structural hazards, yet the concerns of seismic hazards are relatively found unanswered. These seismic hazards are prime matter of concern in Earthquake prone zones or the seismic zones worldwide. Over the period of time the research on structural dynamics, study and analysis of the same are carried on using series of earthquake movements by means of varying the earthquake or the seismic intensity. Studies shows those analyses were being performed on various type of irregularity Considered was (a) Horizontal Irregularity-plan irregularity (b) Vertical Irregularity -Mass Irregularity. The Building with simple geometry in plan & vertical regularity have performed well during strong earthquake but building with T, H & + shaped in plan also these plan vary with each story & vertically irregular structure (i.e. height) have sustained significant damage. To achieve objective of the project Time history Analysis & Response spectrum analysis method were carried out.
