As time has passed, we have noticed that the population is steadily increasing, and the demand for a home is a basic human need, therefore instead of extending along the area, engineers have created vertical extension. As we begin to build the structures vertically upwards, lateral pressures will act on the reinforced concrete Frame. As a result, it is important to resist the forces operating laterally on the frame. In this study, we will evaluate the lateral force operating on a regular (rectangular shaped) and irregular (U shaped) structure with 22 floors, and compare it to two distinct structural systems, namely a framed tube structural system and tube in tube structural system. Response spectrum analysis will be performed in order to compute the results by ETABS V 18.0.1. The study as a whole is a preliminary attempt to assess the effect of vertical forces operating on RC buildings in terms of dynamic parameters such as Story Displacement, Base Shear and Story Drift. ETABS is integrated with all of the major analysis engines, such as static, dynamic, linear, and non-linear, and this software is used to analyse and design buildings, particularly RCC and steel structures, because of the facilities provided in this software at the modelling stage, the buildings can be modelled as per the arrangement of the project members in practise. Gravity loads such as dead and live loads shall be examined in accordance with IS 875 Parts 1 and 2, and horizontal loading impacts such as seismic/earthquake and wind loads will be assessed in accordance with IS 1893 and IS 875 Part 3.
