        abstract = {The increasing demand for vertical urban development has led to widespread construction of high-rise buildings in high seismic regions. This study investigates the effect of X-type steel bracing on the seismic response of a G+20 reinforced concrete (RC) building analyzed using five PEER NGA-West2 ground motion records scaled to IS 1893:2016 Zone V (PGA = 0.36g). The structure is modeled in ETABS v21 with a moment-resisting frame combined with a central shear wall core. Both unbraced and X-braced configurations are evaluated through Nonlinear Time History Analysis (NLTHA). Key parameters story displacement, inter-story drift, story shear, and modal characteristics are systematically compared. X-type bracing at Stories 2–4, 7–10, 15–18, and 19–20 reduces maximum roof displacement by 48% in X-direction and 26% in Y-direction, decreases the fundamental period by 11.3% (stiffness increase of 27%), reduces maximum inter-story drift by 37.4%, and lowers base shear by 16.1%. All drift values remain within the IS 1893:2016 permissible limit of 12 mm. Results confirm that symmetrically placed X-type steel bracing is highly effective for seismic drift control in G+20 RC buildings.},
