Abstract

This paper investigates the numerical modelling analysis and design of non-sway and sway method for multi-storey reinforced concrete frames. Multi-storey buildings having a height of 57.7 and 23.5 m consisting of 15 storeys' and 6 storeys, respectively have been analysed for non-sway and sway condition by using software STAAD. Pro V8i. Column sizes have been changed in every three storeys interval and beam sizes kept constant for the convenience of making the analysis more economical and practical. Reinforced concrete building frames analyses have shown how the reinforcement of the beams and columns has changed with the effect of wind loading. According to the analysis of that reinforced concrete members, it can be seen that the reinforcement of the beams and columns have been increased significantly in sway frame compare to the non-sway frame. However, two multi-storey reinforced concrete building frames (one tall and another one short) analysis also indicated how the beam and column design is affected by the height of the building. This paper also highlighted the response of reinforced concrete multi-storey building frames that can be predicted effectively with the software analysis.
