Comparison of the tube frame and tube in tube frame structure with rectangular and U-shape building

As time has passed, we have observed that the population is steadily increasing, and the need for a home is a basic human need, so engineers have created vertical extensions rather than extending along the area. Lateral pressures will act on the reinforced concrete Frame as we begin to build the structures vertically upwards. As a result, it is critical to resist forces acting laterally on the frame. We will compare the lateral force acting on a regular (rectangular shaped) and irregular (U shaped) structure with 22 floors to two structural systems, a framed tube structural system and a tube in tube structural system, in this study. ETABS V 18.0.1 will perform response spectrum analysis to compute the results. The overall study is a preliminary attempt to assess the effect of vertical forces on RC buildings using dynamic parameters like Story Displacement, Base Shear, and Story Drift. ETABS is integrated with major analysis engines and this software is used to analyse and design buildings, particularly RCC and steel structures. Gravity loads, such as dead and live loads, must be evaluated in accordance with IS 875 Parts 1 and 2, and horizontal loading impacts, such as seismic/earthquake and wind loads,are evaluated in accordance with IS 1893 and IS 875 Part 3.
