COMPARISON BETWEEN SPECIALLY SHAPED COLUMNS AND RECTANGULAR COLUMNS IN R.C. STRUCTURE
Keywords:
Earthquake, Rectangular columns, Specially shaped columns, Displacements, DriftsAbstract
The objective of this study is to assess the comparative seismic performance of buildings with Rectangular
columns and buildings with Specially shaped columns. Four different buildings (i.e. 6 story, 9 story, 12 story and 15
story) are analyzed using Equivalent static analysis for zone III in Amravati. The maximum story drift and lateral
displacement are calculated. The cost comparison is done between building with rectangular columns and the building
with specially shaped columns in this study. ETABS v9.7.4 software is used for the analysis and design. It is observed
that the seismic performance of the building with specially shaped columns is better as compared to the building with
rectangular columns and also the cost required is less.
