Abstract-– Buildings often provide individuals’ shade. Construction of large structures is necessary because most people prefer solitude. Tall buildings have the drawback of being less earthquake-resistant. Therefore, tall buildings constructed in seismically active areas may sustain serious damage or even die. Therefore, a building’s construction must be capable of withstanding the lateral and gravitational forces generated by earthquakes. Multi-story buildings employ a specific method to withstand lateral loads. The storey’s RC-framed construction used three distinct bracing methods. We have examined and assessed the G+14 stored RC frame design for seismic zone IV. We use computer-aided software, STAAD Pro V8i, to analyse the RC-framed models using the Response Spectrum Method. We examined the structural behaviour using a range of bracing methods, including X-bracing, inverted-V bracing, and V-bracing. We placed these techniques at different positions on the outer faces and all four sides of the constructions. We examine the parameters of time, base shear, storey drift, storey displacement, bending moment, and peak storey shear for both braced and unbraced models. The braced frame’s base shear value increases compared to an unbraced frame, while its storey displacement, storey drift, bending moment, and duration decrease. The braced frames have higher peak story shear values. The model with X-bracing on the mid-bays of the buildings’ exterior sides significantly increases the structure’s stiffness when compared to the alternative bracing technique.
