Response of Regular and Irregular RCC Buildings, Comparison of Seismic Provisions, Seismic Analysis


Earthquake is a very important aspect to be considered while designing structures. Lots of work has been reported by many researchers who have worked to study the effect of structures with irregular plan and shape. In recent years, there has been a significant rise in usages of irregular structures in plan. Irregular buildings constitute a large portion of the modern urban infrastructures. Such irregular structures needs to be taken care by structural engineers especially in a high seismic zones. Unexpected effects can be observed on irregular structures under various load patterns and it causes extra shear, torsion etc. Asymmetry in the plan increases stresses of certain structural elements. Hence it is necessary to choose good building configuration. This paper presents a comparison of the seismic provisions of the two seismic codes, namely IBC-2012 (International building code 2012) and IS-1893-2002 (Indian Standard-Criteria for Earthquake Resistant Design of Structures, Part-1, General Provisions and Buildings). For this study, two plans of G+7 storey reinforced concrete framed buildings have been selected. The first one is a regular in plan which has rectangular-shape and second one is irregular in plan which has T-shape. For analysis, both selected shapes of building are analyzed by STAAD. Pro V8i SS6 software and the analysis is done by Linear Static Method. The aim of this study is to compare provisions of IBC-2012 and IS-1893-2002 codes and study the response of irregular buildings. Conclusions are made on the basis of comparisons of various structural parameters of building.
