Study on behaviour of uniaxial column bonded with basalt FRP wraps

Abstract

The resistances of the structure along with stability provided by columns under different load
conditions have an impact in determining the overall performance of the structure. Thus any deficiency caused
by the supporting columns may affect the operation of the supporting member and the structure itself.
Therefore it is necessary that the column should provide adequate strength for which it is designed for
throughout its life. But it is noticed that due to improper design, changing the purpose of use of structure, and
damage caused due to earthquake or impact load in the structural member. Due to this the column can possibly
subjected to load greater than the design loads. To overcome the deficiency discussed, the column needs
strengthening in order to ensure that the structure can overcome all the odds.
In this study, the behaviour of uniaxial column reinforced with basalt fibre reinforced polymer fabrics
(BFRP) was carried out. The columns wrapped with different types of FRP materials shows increase in
capacity having different configurations. In this study the effect of Basalt FRP was found. Hence, the
specimens in the form of C shape were casted and their behaviour with Basalt FRP is observed.
