Seismic Analysis of Multi-Story RCC Framed Buildings with Symmetric and Asymmetric Design

A disruptive disturbance known as an earthquake occurs when subterranean movement along a fault line causes the earth's surface to tremble. An earthquake is a natural disaster that has claimed millions of lives throughout history. Due to fatalities and destruction, every earthquake leaves a path of suffering. The bhuj earthquake was the first time when multi-story reinforced concrete buildings in India experienced a significant ground motion shaking. The main causes of failure have been determined to be soft stories, floating columns, irregular masses, subpar building materials and bad construction techniques, uneven earthquake response, soil and foundation, and the impact of pounding on nearby structures. The main purpose of structural analysis is to ascertain how a structure will respond to loads, which can be either dynamic (such as the weight of people, furniture, etc.) Or static (such as wind, explosions, and earthquakes). Movement beneath the earth's surface causes earthquakes, which create varying degrees of ground shaking that can lead to building damage and collapse. The lateral loads brought on by earthquakes must be taken into account in tall constructions. Seismic design techniques ensure that the building is useful by ensuring that it can sustain moderate and frequent shaking without suffering damage. Two buildings (g+4) that are thought to be located in seismic zone iv are the subject of the current study's load analysis. The etabs 16 software is used for both the response spectrum approach and the equivalent static analysis method. Parameters such as storey displacements, storey drift, storey stiffness, support reaction, axial force, bending moment, and shear force in columns, as well as bending moment and shear forces in beams, are determined for comparative study based on the analysis results. Because the response spectrum analysis approach is more cost-effective than the static analysis method, it should be considered for high-rise buildings, according to the results.
