Comparative Analysis of Lateral Loads Resisting System for RCC Structure

Abstract

Abstract: This research work focuses on comparison of seismic analysis of G+12 story buildings stiffened with shear wall at various locations. The performance of the building is analysed in Zone II, for Mumbai city. This research paper includes understanding the main zone factor that tends the structure to perform poorly during lateral moments caused by earthquake in order to achieve their appropriate behaviour under future earthquakes. The analysed structure is symmetrical, G+12, Ordinary RC moment-resting frame (OMRF). Modelling of the structure is done by using staad proV8i software. The Time period used for the seismic calculations of the structure in both the direction is achieved from the software and as per IS 1893(part I):2016 seismic analysis has conducted. The Lateral seismic forces of RC frame are carried out using equivalent static method as per IS 1893(part I): 2016. The purpose of present work is to understand that the structures need to have suitable Earthquake resisting features to safely resist large lateral forces exerted on structure during lateral movement of structure. Shear walls are efficient (model no.3), In terms of effectiveness in minimizing lateral movement and damage caused due to the earthquake in structure the conventional frame system also provides the resistance to structure but it is unable to minimise the damage caused by the earthquake in structure. A comparative analysis is done in terms of Base shear, Displacement, Axial load, Moments in Z direction in columns and maximum bending moments in beams.
