WALL

VS BRACINGS

Consider recent construction and its failures in India and also helps well as its urbanization. And also, well as considering the elemental entities like industrialization, include in multi-story structures when the surface is considered to be in non-uniform. What is known as slope, considering the construction of the multi-story under these areas, is one of the important and also as well as Complex task. So, in order to overcome this systemic and all kind of load which affects the story while constructing in the area of slope for hilly regions. Extra support is needed to be given to the structure in order to reduce the effects. Considering the structure to be lying on the areas where the slope is a major factor. Sometimes the effect is unpredictable, hence the elements like bracings, shear wall and also as well as fluid viscous damper, is necessary to be provided in order to safeguard the multi-story structure. All the analysis has been considered under the code of response spectrum analysis considering the code book IS 1893:2002 all the valid values has been considered and respect to page number is also be noted in further project details. Response spectrum is one of the best methodologies in order to study the number of modes of the elements under the application of different loads. The main aim of the is to analyses the model under the behavior of the RCC structure over bracings and also as well as shear wall including fluid viscous damper

Key words: FVD, Shear Wall, Bracings, Response Spectrum,slope.

[1]INTRODUCTION

As discussed the multi-story structure considering its construction in the slope area is one of the most complicated task, and also it is considered to be most dangerous where due to the sudden drop in the climate which directly affects the ground levels and causes the ground to undergo a process of erosion where the construction of the multi-story structure will become much and much complicated. Hence we need to consider some of the important factor which can we overcome these effects, and to provide most long life effect to the structure to overcome all the climate changes including

soil Erosion as well. So it is important to consider many elements like share wall at different locations and providingthesharewallattheSamelocationasproviding thebracingsandalsoaswellasfluidviscousdamper.

TheanalysisiscarriedoutusingETABS

Introduction to ETABS

ETABS is software used for analysis purpose and also in design of buildings. ETABS is characterized by powerful graphicalinterfacecoupledwithcommondatabasewhich is integrated with unmatched modelling, analysis, design anddetailingprocedures

Merits of ETABS

ETABS includes various features with which geometryofabuildinghavingsimpleandstraight forward symmetry with horizontal beam and vertical columns and floors can be established withminimumefforts. 





ETABS reduces the modelling and design time of the building having many floors but similar structure.

ETABS gives the accurate design of the structure with formulation of member stiffness in the buildings having small or large bay width and story height. These dimensions highly affect the stiffnessoftheframe
