It is very necessary to determineeffective, efficient and ideal location of shearwall.In this paper Study of G+5 Storey building inZone IV is presented with some preliminaryinvestigation which is analyzed by changingvarious position of shear wall with differentshapes for determine parameter like axial loadand moments. This analysis is done by usingStandard package STADD-pro.Keywords – Shear wall, Seismic loading, lateralloading, drift, axial load.I. INTRODUCTIONShear walls are a type of structural systemthat provides lateral resistance building orstructure. Shear walls are vertical elements of thehorizontal force resisting system. Shear walls areconstructed to counter the effects of lateral loadacting on a structure. In residential construction,shear walls are straight external walls that typicallyform a box which provides all of the lateral supportfor the building. When shear walls are designedand constructed properly, and they will have thestrength and stiffness to resist the horizontal forces.In building construction a rigid vertical diaphragmcapable of transferring lateral forces from exteriorwalls, floors, and roofs to the ground foundation ina direction parallel to their planes. Examples arethe reinforced-concrete wall or vertical truss.Lateral forces caused by wind, earthquake, anduneven settlement loads, in addition to the weightof structure and occupants; create powerfultwisting (torsion) forces. These forces can literallytear (shear) a building apart. Reinforcing a frameby attaching or placing a rigid wall inside itmaintains the shape of the frame and preventsrotation at the joints. Shear walls are especiallyimportant in high-rise buildings subjected to lateralwind and seismic forces. In the last two decades,shear walls became an important part of mid andhigh-rise residential buildings. As part of anearthquake resistant building design, these wallsare placed in building plans reducing lateraldisplacements under earthquake loads. So shear-wall frame structures are obtained.Shear wall buildings are usually regular in plan andin elevation. However, in some buildings, lowerfloors are used for commercial purposes and thebuildings are characterized with larger plandimensions at those floors. In other cases, there aresetbacks at higher floor levels. Shear wall buildingsare commonly used for residential purposes.Shear wall is wall made to resist lateral forcesacting on tall buildings. It is provided ,when thecentre of gravity of building area & loads acted onit differs by more than 30%. in order to bring thec.g in range of 30% concrete wall is provided i.elateral forces may not increase much.The project describe the analysis of structure witheffect of shear wall. In Structural engineering, ashear wall is a wall composed of braced panels(also known as shear panels) to counter the effectsof lateral load acting on a structure. Wind andearthquake loads are the most common loadsbraced wall lines are designed to counteract.II.

ADVANTAGES OF SHEAR WALLSIN BUILDINGSProperly designed and detailed buildingswith shear walls have shown very goodperformance in past earthquakes. Shear walls inhigh seismic regions require special detailing.However, in past earthquakes, even buildings withsufficient amount of walls that were not speciallydetailed for seismic performance (but had enoughwell-distributed reinforcement) were saved fromcollapse. Shear wall buildings are a popular choicein many earthquake prone countries, like Chile,New Zealand and USA.V. CONCLUSIONDifferent location of shear wall effect on axial loadon the column. In absence of shear wall axial loadand moments are maximum on column. Case-3 issafe as compare to case-1 and case-2. Shear wallsare easy to construct, because reinforcementdetailing of walls is relatively straight forward andtherefore easily implemented at site. Thus shearwalls are one of the most effective buildingelements in resisting lateral forces duringearthquake. By constructing shear walls damagesdue to effect of lateral forces due to earthquake andhigh winds can be minimized. Shear wallsconstruction will provide larger stiffness to thebuildings there by reducing the damage to structureand its contents.REFERENCES1 Definition of shear wall-http://www.wisegeek.com/what-is-a-shear-wall.htm2 Typical shear wall features, uplift in shearwall, location of shear wall-http://www.abag.ca.gov/bayarea/eqmaps/fi...ld002.htm,http://www.abag.ca.gov/bayarea/eqmaps/fi...sld008.htm3 Concrete shear wall construction,http://world-housing.net/uploads/concret...f?pr=Array4 Segmented shear wall design-http://timber.ce.wsu.edu/Supplements/She...rTable.htm5 Wood framed shear wall construction,http://www.shearwalls.com6 Applied Technology Council, 1995.Cyclic Testing of Narrow Plywood ShearWalls - ATC-R-1, University of Californiaat Irvine.7 Arima, T., Okabe, M., Maruyama, N.
