Abstract- Earthquake is a natural calamity that has killed millions of peoples through the ages. Every earthquake leaves a trail of misery because of the loss of life and destruction.
Seismic codes are very important in the designing of multistoried buildings. In order to design an earthquake resistant building, structural engineers must have good knowledge of the various seismic codes. In this study, seismic design provisions in three building codes, IS 1893-2002, 1997 USA (UBC)& Canadian (NRC 2005) are studied. Factors like Importance factor, response reduction factor, seismic zones, soil profile, and Fundamental time period were compared. Recommendations provided by seismic codes help the designer to improve the behavior of structures so that they may withstand the earthquake effects without significant loss. Seismic codes are unique to a particular region or country. They take into account the local seismology, accepted level of seismic risk, properties of available materials, methods used in construction and building typologies.
In this study, a symmetrical G+20 multistoried building was analyzed & designed by computer software Staad Pro using the above mentioned three seismic codes. It was found that the Indian Standard code gave the most economical design whereas the UBC code consumed more steel.

I. INTRODUCTION
A. General
Natural calamities such as earthquakes, tsunamis, landslides, floods etc. cause severe damage and suffering to human beings by collapsing many structures, trapping or killing persons, cutting off transport systems, blocking of navigation systems, animal deaths etc. Such natural disasters are big challenges to the progress of development. However, civil engineers play a major role in minimizing the damages by properly designing the structures or by proper material selection or proper construction procedure and taking other appropriate decisions. This includes understanding the earthquakes, behavior of the materials of construction and structures and the extent to which structural engineers make use of the knowledge in taking proper decisions in designing the structures made of reinforced concrete.
