Abstract

Previous earthquakes in India have discovered that most of the buildings aren't designed to be earthquake resistant. In general, buildings are designed taking into account just the gravity loads. Furthermore, the present look seismic codes are not completely practiced while developing a building. A thus higher degree of damage might be expected during an earthquake in case the seismic resistance of the structure is insufficient. The existing work describes the various reinforced concrete (RC) frames having various irregularities but with same dimensions which are analysed to study the behaviour of theirs when put through seismic lateral loads. All of the frames were analysed with the same strategy as mentioned in IS 1893-Part-1:2002. By the end result, it's been interpreted the base frame (regular) evolves least story drifts while the structure with floating columns shows maximum storey drifts on the soft story levels. Hence, this is very vulnerable to damages under this particular type of loading. The structures with irregularities also proved unsatisfactory consequences to some degree. The frame with heavy loads produces maximum storey shears, which ought to be accounted for design of columns suitably. The evaluation proves that irregularities are unsafe for the buildings and it's crucial that you have regular and simpler shapes of frames in addition to uniform load distribution within the building. Thus, as far as possible irregularities in a construction must be stayed away from. Nevertheless, if irregularities need to be introduced for every reason, they should be designed properly following the circumstances of IS 13920:1993. The complex shaped structures are in current days getting common but they have a threat of sustaining damages during earthquakes. Thus, such buildings must be designed effectively taking proper care of the dynamic behaviour of the Structure.
