Investigation on the Structural Behaviour of High-Rise Structures Exposed to Dynamic Loading in a Seismic Zone using Various Bracing Methods

Bracing is a common method used by multi-story buildings to counteract the lateral stresses that are applied by the environment. In a frame construction, the use of bracing is a method that is both highly effective and cost-efficient in resisting horizontal forces. Structures that have their frames braced are meant to be more resistant to the effects of earthquakes and wind loads. Because of their exceptional rigidity, braced frames are well suited for seismic retrofitting. Steel members are almost always used in the construction of braced frames. Vertical loads are supported by the structural parts of the building, such as beams and columns, whereas lateral loads are supported by the bracing system. By using braced frames, it is possible to minimize the amount of side displacement as well as the bending moment in the columns. Steel bracing is adaptable and can be constructed to fulfill the needed strength and stiffness requirements. In addition to being cost-effective, quick to install, and taking up less space than wood bracing, steel bracing is also gentle on the environment. It makes it possible to obtain a large increase in lateral stiffness while simultaneously increasing weight just a little. This indicates that preexisting constructions that have low side stiffness may considerably benefit from incorporating it. Bracings are given in RCC constructions in order to withstand lateral stresses such as those caused by earthquakes and wind pressure. There are several different kinds of conventional bracing that may be employed. The purpose of this examination is to analyze the dynamic behavior of a multi-story building located in a seismic zone and equipped with a variety of bracings. The work being done right now is on a multi-story structure that is situated in Zone V, and it is being done on three distinct stories: 12, 20, and 30. The research was carried out using X, K, V, and O bracings, as well as X-O, V-O, and K-O bracings for each individual tale. FEM uses SAP 2000 to perform a non-linear time history analysis to complete the research. In addition, we established a number of factors, such as tale displacement and story drift. When compared to other sorts of combinations of bracing and individual bracings, it has been shown that the K-O bracing combination results in 12% less narrative displacement and 11% less story drift
