Abstract

In our country REINFORCED CONCRETE structures are very universally made use of for convention constructions like residential & apartment towers. however, in various nations Steel Sections are favored for the similar erections rather than going for concrete Columns & Beams with the intent of closing the erection quickly & achieve cut back & also to trim down the Section sizes. In here a challenge has been crafted to form a set of models in E tabs. All with steel sections for a G+20 model for Earthquake Zone V. Equivalent Static Method is used for seismic analysis. Shear wall structures consisting of braced panels (shear panels) to resist the lateral load effects acting on the structure. Shear walls are considered to carry wind and seismic loads. It is one of the excellent methods for earthquake resistance design of R.C buildings. During earthquake motion, some of the parameters like weight distribution, strength and stiffness in both horizontal and vertical plane of a building may affect the behavior of a structures Reinforced concrete shear walls are provided in RC framed buildings to reduce the effect of earthquake and also to improve the seismic response of a structure. Bracing system is the one of lateral load resistant concepts in tall structures. This system helps to reduce buckling of beams and columns but increases the strength and stiffness of the structure. Space occupied by the bracings is less and it is easy to erect and also has the flexibility in design for fulfilling the desired stiffness of the structure and also its strength. Bracings may be eccentric or concentric based on the shape; bracings may be classified as X bracings, V bracings, K bracings, and Inverted V bracings. In reinforced concrete structures bracing system is viable solution for resisting lateral loads.
