A bracing system is a component within a structure that counters horizontal forces such as wind, seismic activity, and other loads that may lead to the building swaying or falling. A properly designed bracing system can enhance a building's capacity to endure these forces and reduce harm to both the structure and those inside. The outcome of this research is to investigate the dynamic performance on the structural damage of high-rise building with various brace types. The methodology in this research is combined between experimental and numerical modeling of structures. The materials data of concrete and steel as the braces materials is defined from experimental results. The structures analysis is modeled using SAP2000 software, based on the existing materials data from experimental tests. The outputs reviewed are stiffness, vibration period of structure, displacement, drift, stiffness and ductility. The structural damage potential is connected to dynamic response of the building with braces as well. The dynamic parameters of natural frequency, and vibration period for the V brace shape, inverted-V brace shaped (Ʌ), and X shape (in two floors) are 0.806 Hz; 1.24 s, 0.893 Hz; 1.12 s, and 0.862 Hz; 1.16 s. The ductility of structures with V brace, inverted V brace and X brace (in two floors) are 2.58, 2.95, and 2.85. The result showed that inverted V-shaped bracing has the best dynamic performance than others shapes. Based on modeling results, the building is safe condition under the actual spectra-response that is vibrated the building model. © (2025), (Insight Society). All rights reserved.
