The main objective of this project is to analyze & study the comparative seismic performance of conventional & flat slab structures with and without shear wall using Etabs. In earthquake zone the displacement and drift of the structures will be more so to have more stiffness to the structure shear wall is to be provided therefore this project is compared between conventional slab & flat slab (with drops) building with and without shear wall. The report includes detailed analysis of a multi storey G+9 Commercial building using software ETABs. All the structures were subjected to various kinds of loads such as dead load, live load, earthquake load. This study is mainly based on Response spectrum analysis which is linear dynamic analysis to know the seismic performance of the structures. Analysis were done as per IS:1893-2002, and all the RCC members were designed as per IS: 456-2000. Load Calculations were calculated as per IS: 875 Codes. The results provide best information on storey drifts, displacements, stiffness and storey shears and show its performance on different conditions of the structure
IRJET- SEISMIC ANALYSIS AND DESIGN OF HIGH RISE BUILDING BY USING ETABS IN DIFFERENT SEISMIC ZONES
IRJET, 2021
From the recent earthquake studies, it is concluded that not only non-engineered but also the engineered structures are affected by earthquake. In these days constructions are fitting increasingly narrow and extra inclined to sway and consequently detrimental within the earthquake. Researchers and engineers have worked out within the past to make the constructions as earthquake resistant. So it is necessary to consider and analyze the effect of seismic load in design of a structure. The main objective of this project is to analyze and design a G+10 building in three dimensions for different seismic zones of India. In this work the structure is analyzed including load calculation using ETABS. Various parameters like Storey Drift, Storey Stiffness, Lateral Load and Storey Displacement of the building in different seismic zones are calculated and compared. Limit state method of design is adopted here and IS 1893:2002 is used for seismic analysis and detailing.
Analysis and Design of Earthquake Resisting Building with Shear Walls by Using ETAB Software
International Journal For Multidisciplinary Research
The present study shows the seismic behaviour of buildings under the action of earthquake load by performing Non-linear Static analysis. Nowadays buildings with shear walls are more popular than buildings without shear walls in earthquake-prone areas due to their resistance during earthquakes. So, this study aims to find the prime location of the shear wall and then investigate the effectiveness of the best shear wall for the RCC structure. In this study, G+13 & G+5 RCC building is considered for the analysis under zone I to zone IV with suitable load combination. The structure is analyzed for earthquakes in the type of structural system using ETABS software. The shear wall starts from the foundation level and should continue throughout the building.
Neither the earthquake can be predicted nor it can be stopped as it is natural phenomenon. The only thing is effect of earthquake can be minimized. Earthquake itself is not vulnerable but the fragile and un-engineered structure cause the serious problems during earthquake. So to cope with this problem we need to take care for the construction of earthquake resistant construction. We can't construct earthquake proof structures as term engineering itself depicts economic i.e the project should be completed within the minimum budget including all the facilities. So we should think about minimizing the risk during such phenomenon. So the role of Civil/Structural engineers is to analyze and design of earthquake resistant structures. Here in India there are four seismic zones " zone II, zone III, zone IV and zone V". the paper aims to collect the information for design and analysis of buildings in different seismic zones and interpretation of the results obtained by ETABS software.
A Study of Seismic Analysis of Building Using ETABS
International Journal of Innovative Research in Engineering and Management (IJIREM), 2023
In this era, as urbanization is rapidly increasing the availability of land is becoming less, due to overpopulation and increased land cost. To overcome this rising problem, the only solution is to opt for multistorey buildings. The effective design and construction of earthquake resistant structures have much greater importance all over the world. For this ETABS provides both static and dynamic analysis for a wide range of gravity, thermal and lateral loads. This analysis mainly deals with the study of plans by using AutoCAD software. It is to analyze the design of G+5storey building. Seismic analysis of all types of structures is an important aspect when working in high seismic areas. With the help of seismic analysis, structures can be designed and constructed to withstand strong lateral movements of the crust during earthquakes.
Analysis of Seismic Response of a Unsymmetrical Building(G+13) using Etabs
International Journal For Multidisciplinary Research
From the past records of earthquake, there is increase in the demand of earthquake resisting building which can be fulfilled by providing the shear wall systems in the buildings. In this we have considered an unsymmetrical plan under earthquake load and wind load. There are two models have taken to analyze: - 1. Bare frame structure and 2. Shear wall Structure. Shear walls are generally provided for full height of the frame. Shear wall systems are one of the most used lateral load resisting systems in high-rise buildings. The earthquake and wind load are applied in an unsymmetrical building located at zone-III. A comparative analysis has been done between building having bare frame and shear wall structure. The complete analysis is done using E-TABS Software. Lateral displacement, Time period and story drift are calculated in both the cases. It was observed that Multistoried Buildings with shear wall is more able to resist lateral loads as compared to without shear wall.
The behaviour of G+11 multi story building of regular and irregular configuration under earth quake is complex and it varies of wind loads are assumed to act simultaneously with earth quake loads. In this paper a residential of G+11 multi story building is studied for earth quake and wind load using ETABS and STAAS PRO V8i .Assuming that material property is linear static and dynamic analysis are performed. These analysis are carried out by considering different seismic zones and for each zone the behaviour is assessed by taking three different types of soils namely Hard , Medium and Soft .Different response like story drift, displacements base shear are plotted for different zones and different types of soils.

Seismic Performance Study of Multistoried Buildings with Oblique Columns by using ETABS
Facing a large number of new-type complex structural system and progressively consummate earthquake-resistant theories, the conventional software can no longer meet the needs of calculation and analysis. Meanwhile, some international finite element programs, such as ETABS, were updating themselves but remained respective limitations. China has Circum-Pacific seismic belt and Europe-Asia seismic zone. These two are the largest seismic belts in the world. Densely populated and low seismic capacity buildings, in which the earthquake can be simply summarized as high frequency, wide distribution, high intensity and shallow focal depth was described as the world's most earthquake disaster area. The seismic performance analysis and research of building structures look more indispensable. The Oblique Columns are neither parallel nor at right angles to a specified line means they are slanted or Rotated at an angle. In this present work, concerns with the elastic flexural buckling of doubly symmetric columns with oblique restraints under concentric loading. Oblique restraints cause coupling between the principal axis deflections and rotations, and the flexural buckling mode involves simultaneous bending about both principal axes. The present work deals with a study on the Oblique columns of different angles in high rise building. In this work, a high rise building with Normal Columns & at different locations of Oblique columns is considered for analysis. In this paper, response spectrum analysis was executed, which were also compared following the analysis results. The results of the analysis on the Story shear, Story stiffness, Storey drift and Displacements are compared. The results are presented in the tabular and graphical form.
