Seismic Design and Detailing of RC Framed Structure using E Tabs

Abstract

There is a sudden release of energy resulting in creation of seismic waves hence causing an
earthquake. The land of India is divided into 4 seismic zones from Zone 2 to Zone 5. The size
of the earthquakes ranging from being so weak that they are not even felt and are as strong
so as to destroy whole cities. Structures in seismic prone zones are vulnerable to seismic
excitations. Majority of old structures are constructed without considering seismic hazards.
The excitations occur without warning in areas around the world leading to cause major
damage and fatalities. Hence it is necessary to evaluate the performance of structures under
seismic excitations so as to strengthen them. The two methods available for the same are
classified as Static and Dynamic. Static methods mainly are code compliance whereas
dynamic methods are pushover methods such as response spectra, displacement coefficient
and time history etc. In this paper, a G+4 RC framed structure is analyzed using dynamic
analysis and the results of stresses were compared with different load combinations. The
result obtained is presented in the tabular from and compared using graphical equations.
The analysis has been performed in different seismic zones where the soil type is medium.
