| Summary: | A finite element study was carried out to investigate the effect of positioning hole along reinforced concrete short braced columns in multi-storey buildings. RC columns having different sizes and reinforcement, with holes positioned at the centers of their cross-sections were modeled by LUSAS using three-dimensional non-linear finite element analysis. The ultimate strengths of the columns obtained from the present study is compared with the results obtained from the laboratory testing of the same columns as well as with the design strengths recommended by the BS 8110 and ACI codes of practice. The reduction in the load carrying capacity of columns with holes was highlighted. In conclusion, the analysis results showed significant reduction in their load carrying capacities and the safety factors obtained were much less than the nominal value usually recommended by various codes of practice. |
