Analysis of the Effect of Bracing on the Performance of Reinforced Concrete Structures in Multi-Storey Buildings

Abstract

There are two ways to plan earthquake-resistant buildings, namely, the building is planned to behave elastically during an earthquake or the building is planned to behave inelastically during an earthquake. One effort to ensure that the building remains standing strong due to the impact of an earthquake is to use concentric bracing which functions as a lateral force retainer on the structure of a construction. This study aims to analyze the effect of using bracing with steel profiles on the performance of reinforced concrete structures in three-story buildings with modeling A for buildings without bracing, model B with inverted-V bracing, and model C with cross bracing. Based on the results of data processing and data analysis, it was found that the largest internal force occurred in buildings without using bracing, and the moment acting on the building beam without using bracing was 57.536% greater than that using type X (cross) bracing and 55.817% greater than that of buildings using Inverted-V bracing. The structural performance based on performance-based design for buildings using bracing and buildings without using bracing that were modeled, is categorized into the immediate occupancy level because the maximum total drift value obtained in each building is smaller than 0.01 and the maximum total inelastic drift value is smaller than 0.005.
