The Multistoried buildings structures are in very fascinated use for almost all urban part of living areas such as in
metro cities. In this type the making of irregular shaped buildings have become more often now a day. In these study buildings of
multistoried structure is taken for different cases. This paper presents the modeling of 10 cases in which irregular building has
been considered for analysis such as by making offset at different floors including first, third, fifth, seventh, ninth , eleventh,
thirteenth, fifteenth, seventeenth and nineteenth floors respectively in re-entrant corner of building. The comparative analysis of
different parameters have been done to carry out research by software approach including parameters such as Base shear,
maximum displacement, axial force ,shear force and Bending moment, maximum stresses etc. Structural Stability IRS Case 2
then after IRS case 1 to IRS case 3 may observed and obtained as economical and satisfied as per Indian Standards.
