Abstract:

: In Pakistan, raw material from several sources is utilized in the production of steel bars; consequently, the chemical and mechanical properties of locally manufactured bars differ drastically. According to the reviewed literature, there is a significant amount of variation in the data on rebar yield strength. This unintentionally higher yield strength might have serious consequences on a reinforced concrete (RC) column, as the failure mode could shift from ductile to brittle. The purpose of this study is to investigate the repercussions of an unintentionally higher rebar yield strength on an RC column. In order to mitigate the effects of an unintentionally higher rebar yield strength on the behaviour of the RC column, some modifications to the design approach are recommended.
