Seismic evaluation of high rises buildings using a variety of bracing approaches

When the earthquake hit, most of the reinforced concrete buildings in the area collapsed. Therefore, picking a robust system to withstand lateral loads is pointless. The performance of a structure is greatly impacted by its bracing system. The purpose of this research was to compare and contrast several bracing systems for a 15-story reinforced concrete structure. Maximum story lateral displacement, story shear, story drift, and lateral load resisting capacity of the building were some of the construction characteristics examined across the models. ETAB software was used for the analysis of the models in a seismic zone VI setting with medium-condition soil according to the Indian Standard 1893: 2002. The ETAB software was used to conduct a seismic examination of the reinforced concrete building and track its performance over time. Software analysis evaluated the performance of a bare frame model against that of models with various bracing systems, such as the X, V, inverted, and corner X bracing systems. Lateral movement, story drift, and member forces were also analyzed. Bracing systems of all types were shown to be effective in reducing the structure’s lateral displacement and story drift and increasing its resistive capacity. The seismic waves and horizontal load were successfully resisted by all types of bracing systems. The lateral movement was minimized, however, by employing an X-bracing system. The ETAB program performed all of the necessary analyses.
