COMPARATIVE STUDY OF INDUSTRIAL BUILDING SHEDS MADE OF STEEL AND CONCRETEAbstract
The seismic vibrations cause random ground motions, in all possible directions emanating from the epicentre. The ground motions in vertical directions are rare, but an earthquake is always accompanied with horizontal ground shaking. The vibration of the ground causes the structures to vibrate, developing inertial forces. As the earthquake changes directions, it can cause reversal of stresses in the structural components, that is, tension may change to compression and compression ma change to tension. Earthquake can cause generation of high stresses, which can lead to yielding of structures and large deformations, rendering the structure non-functional and unserviceable. The large storey drifts can make a building unsafe for the occupants to continue living. The most commonly adopted buildings construction practices in India are the Reinforced Concrete Frames. With growing economy, the need for construction of industries and factories is increasing day by day. With industrial structures, not only the building has to take up gravity loads, but as well as lateral forces. Many important Indian cities fall under high risk seismic zones, hence strengthening of industrial buildings for lateral forces is a prerequisite. In this study the aim is to analyse the seismic response of an Industrial structure to ground motion using Response Spectrum Analysis. This analysis is performed in various codal provisions (namely Indian, American, and European codes) in Staad Pro. And change in the time period, base shear, maximum deflection, maximum axial force, maximum Bending moments of columns in Y & Z directions, percentage mass participation factors, mode shapes and Sa/g vs Time period graphs are observed and compared. The earth quake parameters, codal provisions & site conditions are different in different countries, but the structural analysis concept of Response spectrum analysis has to be same. So, if a structure fails in codal provisions of one code, then using the same theory prescribed by other code (of course, empherical values may change), we may pass the structure. This is the purpose of the comparison & to know which code is superior to other in terms of response spectrum analysis.
