A Study on Seismic Effect on High Rise Building With & Without Shear Wall

: In this paper we compare & analyze on high rise building, in this we included the reactions of seismic & effect of wind. In past years many research done on Analysis of building with and without shear walls. All the same we work for little Analysis of high rise building (G+10) with & without shear walls. The current work consist the correlation between framed & framed with shear wall building in presence wind force, earthquake force, etc For seismic design of buildings, reinforcement concrete structural walls or shear walls are higher earthquake resisting members which abstain from lateral load resistance. In RC plates (shear wall) have properties of inelastic & stiffened member. It is a part of structure which is provided for resisting horizontal forces (like wind force, earthquake force, etc). It is very essential to determine capable, and ideal location of shear wall. In this paper we study of G+10 Storey building in Zone IV is conferred. In this article focuses on two different models with and without using shear walls in high rise building at different positions. This analysis is done by using STADD-pro Software by seismic analysis & wind effect.

It's considered a five storey building which is subjected to Earthquake loading zone V to determine parameters like storey displacement, storey acceleration and base shear.Models were studied in V zone comparing lateral displacement, base shear and storey acceleration in X and Y direction for all structural models under consideration.Amit Paul, G.D. Dhawle .The earthquake on high rise building in different position of shear wall using STAAD Pro to work out effective ,ideal location of shear wall, as much less economical in G+7 High rise building in Zone IV.R.C .Bush, Anoop I. Shirkol.According to the Indian Code IS1893:2016, the dynamic method is a mandatory analysis procedure that needs to be performed in a structure if the height of the building exceeds 15 meters or if the structure is located in Zone IV [15].Both the response spectrum method and the time history method are suitable for dynamic analysis.
Ashok Thakur , Arvinder Singh.The principle objective of this paper is to analyse and design a multistoried building [G + 4(3 dimensional frame)] using STAAD Pro.The design involves load calculations manually and analyzing the whole structure by STAAD Pro.STAAD.Pro features a user friendly interface, visualization tools, powerful analysis and design engines with advanced finite element and dynamic analysis.
Mr.Hardik Mandwe, Simran Kagale.These buildings general used RCC framed structures subjected to vertical as well as horizontal loads.But for the buildings taller than 15 to 20 stories this system is not adequate because it does not provide the required lateral stiffness.Aim of the present study is to compare the behavior of multi-storey building with shear wall to analyze the effect of building height on the performance under earthquake forces.K VenkateshT.Venkatdas.In this paper the analytical study on the lateral behavior of the structure is mainly concentrated and how it is varying in the different zones of zone II and zone III wit heights of a 6storey, 11storey, and 16 storey structure.The study also involves the orientation of shear wall.

A Modal Analysis determines the vibration characteristics (natural frequencies and mode shapes) of the structure or a machine component.It can also serve as a starting point for another, more detailed, dynamic analysis, such as a transient dynamic analysis, a harmonic response analysis, or a spectrum analysis.The natural frequencies and mode shapes are important parameters in the design of a structure for dynamic loading conditions.Akansha Dwivedi.B.S Tyagi.In this paper effectiveness of shear wall in RCC building and building with composite columns have been studied with the help of four different models using Etabs in zone IV .The analysis is done by response spectrum analysis method and static analysis method.The models considered for the analysis are as follows: Model 1 is RCC building without shear wall, Model 2 is RCC building with shear wall, Model 3 is building with composite columns having no shear wall and Model 4 is building with composite columns in presence of shear wall Mr. Ankur vaidya, Mr. Shahayajali Sayyed.In this paper review of different researchers on the concept of multistoried building with and without shear wall is paraphrased.In India, most adopted type of earthquake resistant structures is with shear wall.These structural walls may differ based on their design and utility and their position in any building plays an important role for resisting lateral force.
Abhishek Mishra, Surjeet Verma, Kumar Vanshaj.A G+25 multistory frame with eight different locations of shear walls situated in seismic zone IV have been taken for the purpose of the study.The size of the building in plan is 18 m x 18m.Height of each story = 3m, Size of Column = 600mm x 500mm, Size of Beam = 500mm x 400mm, Shear wall thickness = 150mm, Concrete Mix Used = M30, steel=Fe 415 All the supports are assumed to be fixed in nature.All the structural properties of building and dimensions as shown in the table no.1.Damping ratio 5% and soil type is taken as medium for all the 2 different models are without shear wall and with shear wall at corner.

Define Loads
;-There are different types of loads acting on the Structure as per Indian standards.

3.1.1.Dead loads:
-All permanent construction of the structure form the dead loads.The dead loads comprise of the weights of walls, partitions floor finishes, false floors and the other permanent construction in the structure

3.1.2.Live loads:
-Live load is produced by the intended use or tenency of a building including the weight of movable partitions, distributed and concentrated loads, load due to impact and vibration and dust loads.Imposed loads do not include loads due to wind, seismic activity, snow, and loads imposed due to temperature and differential settlement.

Wind loads:
-Wind loads is air in the motion rotation and differences in the terrestrial radiation relative to the surface of the earth.

Seismic loads:
-Seismic loads is the basic concept of earthquake engineering.Which means application of earthquake generated agitation to a building structure or its model.It happens at contact surfaces of a structure either with the ground, or with the adjacent structures, or with the gravity waves from tsunami.Seismic loading depends primarily on: Anticipated earthquake parameters at the site, of the site, geotechnical parameters building structure's.

SEISMIC ANALYSIS METHODS .Seismic analysis is a major tool in earthquake engineering
which is used to understand the response of buildings due to seismic excitations in a simpler manner.In the past the buildings were designed just for gravity loads and seismic analysis is a recent development.It is a part of structural analysis and a part of structural design where earthquake is prevalent.There are different types of earthquake analysis methods in which one of them used in this project .I. Equivalent Static program Analysis.II.Response Spectrum Analysis .III.Time History Analysis.IV.Non Linear Static Analysis.

I.Equivalent Static Program Analysis:
The equivalent static analysis procedure is essentially an elastic design technique.It is, however, simple to apply than the multi-model response method, with the absolute simplifying assumptions being arguably more consistent with other assumptions absolute elsewhere in the design procedure.

II.Response Spectrum Analysis:
This approach permits the multiple modes of response of a building to be taken into account.This is required in many building codes for all except for very simple or very complex structures.The structural response can be defined as a combination of many modes.Computer analysis can be used to determine these modes for a structure.For each mode, a response is obtained from the design spectrum, corresponding to the modal frequency and the modal mass, and then they are combined to estimate the total response of the structure.In this the magnitude of forces in all directions is calculated and then effects on the building is observed.
III.Time History Analysis: Time history analysis techniques involve the stepwise solution in the time domain of the multi degree-of-freedom equations of motion which represent the actual response of a building.It is the most sophisticated analysis available to a structural engineer.Its solution is a direct function of the earthquake ground motion selected as an input parameter for a specific building.This analysis technique is usually limited to checking the suitability of assumptions made during the design of important structures rather than a method of assigning lateral forces themselves.

IV.Non Linear Static Analysis:
It is an improvement of linear static or dynamic analysis as it allows the inelastic behavior of the structure.But one thing is unchanged as it assumes a set of static incremental lateral load over the height of the structure.This analysis is also known as "pushover" analysis.A pattern of forces is applied to a structural model including non-linear properties and the total force is plotted with reference to displacement to depict a capacity curve.This can then be combined with a demand curve (typically in the form of an Acceleration-Displacement Response Spectrum (ADRS)) hence reducing the problem to an SDOF System.Moreover, this analysis is simpler, gives information on strength, deformation, ductility and the distribution of demands.Along with advantages it has some limitation like it neglects the variation in loading patterns and also the effect of resonance and higher modes influence on buildings.

CONCLUSION &DISCUSSION :
-We study about some aspects of performance of shear wall & without shear wall building with the help of many structural software.After reading the research papers of many researchers, I have tried to implement in this paper .In this paper ,I have included seismic effect ,wind effect,& all necessary loads included under the Is codes together in this paper.In this we principally research about storey (lateral) displacement & bending moment at z direction, shear force at y-direction& axial force at x-direction is found & compared to the shear wall & without hear wall models.We have done the comparable research of both structures With the help STAAD.PRO software.

FUTURE SCOPE :
-In new era of construction.shear wall building is a updated type of building in current time period instead of without shear wall building.Now a days there are many natural disaster happening ,we have to design building according to them that can reduce its effect.
