Raisoni Academy of Engineering & Technology, Nagpur Abstract— Earthquakes are major natural destruction, responsible for loss of life and damage of property. For decreasing these damages in multi storied building we can apply bracing. The Bracing is attached to provide lateral support to wall framing. Metal straps, timber or sheet bracing can be used for bracing. A typical G+14th story regular RC frame building is designed for various types of bracing like X-bracing, inverted chevron, braced chevron brace, k bracing and carried out through seismic analysis. Three types of different section for same cross sectional area. i.e. ISA,ISMC,ISLB sections are used to compare for same patterns of bracing with unbraced building. The principle objective is to arriving to suitable configuration, modelling, developing models for seismic analysis and design of Multi Storey Building.

Earthquake occurs due to sudden transient motion of the ground as a result of release of elastic energy in a matter of few seconds. The impact of the event is most traumatic because it affects large area, occurs all on a sudden and unpredictable. They can cause large scale loss of life and property and disrupts essential services such as water supply, sewerage systems, communication and power, transport etc. They not only destroy villages, towns and cities but the aftermath leads to destabilize the economic and social structure of the nation. In the RC structure, reinforced concrete frames are used as part of seismic force-resisting systems in buildings that are designed to resist earthquakes. Beams, columns, and beam-column joints in moment frames are proportioned and detailed to resist flexural, axial, and shearing actions that result as a building sways through multiple displacement cycles during strong earthquake ground shaking. Special proportioning and detailing requirements result in a frame capable of resisting strong earthquake shaking without significant loss of stiffness or strength. During earthquake bracing is reduce the deflection in the structure. It works like a Retrofitting of the structure. A bracing system can be defined as a structural system capable of resisting horizontal actions and limiting horizontal deformations. On the basis of this definition, all the systems shown in following figure can be considered bracing systems. Within one building more than one of these systems can be present. In that case some systems are more effective than others in resisting horizontal loads, the others are neglected. II. OBJECTIVES OF THE PROJECT The Main objective of the project is to analyse the high rise RC framed structure on STADD PRO affected by different load to resisting the element and to developed suitable seismic load factors to prevent structural collapse under earthquakes and The multi storey building is to be considered to check effectiveness of bracing system in high rise building. III. MODELING AND ANALYSIS OF BUILDING Different types of bracing pattern used in the study are shown in below Fig. 1: Elevation of Unbraced Fig. 2: Elevation of X-Bracing
