Abstract |
|
The present study aims at understanding the importance of codal provisions, which are particularly provided for the analysis of torsionally unbalanced structures. IS 1893-2002 Part 1 Code gives the information about number of parameters which influences the irregularity of the structure. However, in the present study, the worst affected irregularity under the influence of torsion are studied, In the present study, dynamic analysis has been performed by Equivalent Lateral Force Method (ELF) i.e., the codal method, for all zones and for all soil types with various irregularities such as mass irregularity, diaphragm irregularity, re-entrant corners irregularity, Non parallel offset irregularity for 10, 15 and 20 storey buildings. The results in the form of torsional moment, fundamental time period and base shear results are compared for different irregularities and the analysis is done with Etabs 9.7 software. |
