Abstract

In recent years, as the economy of country grows, vast construction is done in our country. Among which majority of people have consulted with skilled persons, and there are some who constructed without involvement of professionals. In such scenario professionals to the best of their knowledge followed the techniques as mentioned in IS code for a column. But in those cases where professionals are not consulted and unskilled person construct the columns without following the norms/guideline of IS code, how it effects to the behavior of column.  In this research a study is done to check the behavior of short concrete columns with IS norms and without IS norms. In this study a series of nine one-third scale square reinforced concrete columns specimens having cross sectional dimension as 150´150 mm with height of 960 mm were casted. The overall response of the specimens was investigated in terms of load carrying capacity, axial displacement, lateral displacement, and ductility. The test results indicated that reinforced concrete square columns casted as per IS specification have better in axial load capacity, axial and lateral displacement, compared to the columns without any IS specifications. Furthermore, the columns as per IS specification failed in a ductile manner compared to the brittle failure exhibited by columns without IS specifications.
