Abstract

An earthquake is a sudden, rapid shaking of the earth caused by the breaking and shifting of rock beneath the earth’s surface. Earthquakes are among the most powerful events on earth, and their results can be terrifying. In0general for0design of tall0buildings both0wind as well0as earthquake0loads need0to be0considered. Governing0criteria for0carrying out0dynamic analyses0for earthquake0loads are different0from wind0loads. However many tall buildings are not so resistant in lateral loads due to earthquake. Reinforced concrete multi-storied buildings in India were for the first time subjected to a strong ground motion shaking in Bhuj earthquake. It has been concluded that the principal reasons of failure may be attributed to soft stories, floating columns, mass irregularities, poor quality of construction materials faulty construction methods, unstable earthquake response, soil and infrastructure, which were determined to cause damage to the attached structure. High-rise buildings are in high demand due to global urbanization and population growth, and high-rise buildings are likely to suffer the most damage from earthquakes. Since earthquake forces are irregular and unnatural in nature, engineering tools need to be sharpened to analyze the structure in the work of these forces. In this study, to understand the behaviour of structure located in seismic zones III for G+15 Multi-Purpose storey building model is considered for study. Performance of frame is studied through Response Spectrum analysis and comparison is made on shear force, storey drift, storey displacement and storey stiffness.

Highlights

  • An earthquake is a sudden tremble or movement of the earth‘s crust which originates naturally at or below the surface

  • High-rise buildings are in high demand due to global urbanization and population growth, and high-rise buildings are likely to suffer the most damage from earthquakes

  • Performance of frame is studied through Response Spectrum analysis and comparison is made on shear force, storey drift, storey displacement and storey stiffness

Summary

INTRODUCTION

An earthquake is a sudden tremble or movement of the earth‘s crust which originates naturally at or below the surface. The word regular is vital here, since it prohibits stun waves caused by atomic tests, man-made blasts and so forth. The whole world is comprised of plates. The intersection between the two plates is called as fault. This fault in the Indian Context is the main boundary, fault extending through the terrain region all the way from west along Himachal Pradesh through Uttaranchal, Bihar, Assam to Burma. That plate descends through Andaman-Nicobar Islands and Bay of Bengal and into Indonesia. As the plate moves the rocks are subjected to stress, suddenly a fracture develops and this fracture is called as an earthquake. In The present study we are using E-tabs software to design the Building in seismic zone III and to different the property and its results
