“…In horizontal load applications such as earthquake and wind loads, geometric irregularity plays a signi cant role in the response behavior of buildings in terms of displacement, natural frequency, time, stiffness, velocity, and acceleration of the structure [1]. The time history analysis has been selected to check the dynamic response for the models under the earthquake conditions in seismic Zone IV [25,16]. The time displacement is higher in a geometrically more irregular structure (M2) than in one less irregular (M3).…”

Over the few decades, irregularly shaped structures are famous in modern times because of their architectural signi cance. Symmetrical plan structures often exist, although irregular plan structure is practiced in developing nations. This study investigates the effect of geometric irregularity in reinforced concrete (RC) frame structures under seismic zone IV by using the software STAAD Pro. Moreover, the time displacement on the nodes from where the geometric irregularity starts has been analyzed. Three types of 8-Storey's frame models were considered for the dynamic behaviors, i.e., models M1, M2, and M3. Model M3 is geometrically regular in the x-y-plane, and geometric regularity is interrupted in models M1(less disturbed) and M2 (more disturbed) in the identical plane. The results showed that the time displacement is more geometrically more irregular structures. The time-frequency increases in each mode, which means the higher method has a higher frequency and more in a more geometrically rare form. The irregularity of the structures' geometricity is re ected in the irregularity shape factor (ISF).According to the nding, the rough geometrical shape signi cantly impacts the dynamic response of the building, and ISF of 0.26 (M2) and 0.24 (M1) greatly varies with frequency, period, velocity, acceleration, and displacements.
