Many existing reinforced concrete frame buildings located in seismic zones are deficient to withstand moderateto severe earthquakes. Insufficient lateral resistance along with poor detailing of reinforcement is the main reasons forinadequate seismic performance of the buildings. Such buildings with no ductile detailing represents considerablehazard during earthquake. As a result, they suffer severe damage and are responsible for most of the loss of life even forsmall magnitude of earthquake. In recent years, a significant amount of research has been devoted to the study of variousstrengthening techniques i.e. to increase the lateral stiffness and resistance to enhance the seismic performance ofreinforced concrete multi-storied buildings, however, the attempt by using various arrangements of bracing system inmulti-storied building has not been made.It is therefore important to develop an effective and economical seismic resistance system so that the buildings canwithstand to moderate or severe earthquake. In the present research study, an attempt has been made to increase thestiffness of the multi-storied or tall buildings by using bracing system. As a result of this, lateral maximum deflection canbe controlled. To achieve these objectives, an analytical study has been carried out by studying G+10 storey reinforcedconcrete building by using versatile and practical analytical tool such as STAAD.pro 2007. A number of different modelsincorporating various positions of bracings have been developed. Of the different methodologies, Equivalent StaticMethod & Response Spectrum Method of seismic analysis has been adopted with view to understand the accuratedynamic parameters. The study reveals that, storey drift, as well as element displacements is reduce d considerably andare well within permissible limits.
