IRJET- 3D Frame Analysis by using ETABS
0 likes44 views
This document presents a study analyzing a 4-story building frame using the software ETABS. A 16m x 16m building with 4m story height was modeled. Dead loads, live loads, and seismic loads were applied. Both 2D and 3D frame analysis was performed to investigate the effect of gravity and lateral loads on the base shear value. Graphs of the axial force diagram, axial loads in columns, base shear values, and vertical distribution of base shear to floors are presented. The final base shear value and distribution to floors is calculated and presented.

A parametric study for static analysis is performed to investigate the effect of gravity load and lateral load on frame. Key Words: 2D FE, 3D FE, Baseshear,Gravityload,lateral load. 1. INTRODUCTION ETABS is the present-day leading design software in the market. Many design company’s use this software for their project design purpose. It is easy to use, special purpose analysis and design program developed specifically for building system. ETABS features an intuitive and powerful graphical interface coupled with unmatched modeling, analytical, design and detailing procedure in all. Integrated using a common database. Although quick and easy for simple structure ETABS can also handlethelargestandmost complex building models, including a wide range of nonlinear behaviors necessary for performance-based design making it the tool of choice for structural engineersin the building industry. 1.1 Advantages of ETABS Dating back more than 40 years to the original development of ETABS the predecessorof ETABS,it was clearly recognized that buildings constituted a very special class of structure. Early releases of ETABS provided input, output and numerical solution techniques that took into consideration the characteristics unique to building type structure. 2. 2D FRAMES SUBJECTED TO GRAVITY LOAD AND LATERAL LOADS A 16m X 16m, 4 storey multi storey regular structure is considered for the study. Story height is 4m. Modeling and analysis of the structure is done on ETABS software. 2.1 Preliminary Data: Length x Width 16m x 16m No of Story’s 4(G+3) Beam 450mm x 300mm Columns 600mm x 300mm Slab thickness 150mm Support condition Fixed Thickness External Wall 120mm Grade of concrete and steel M30 and Fe415 Length of each bay 4m 2.2 Loading Consideration Loads acting on structure are dead load (DL), Live Load (IL) and Earthquake Load (EL) DL; self weight of the structure, Floor load and Wall loads. Live Load: 3KN/m2 Importance Factor: 1 Seismic Zone: II Soil Type: II Zone Factor: 0.10 Response Reduction: R=5 Time period: 0.427 sec (calculated as per IS 1893:2002) 2.3 ANALYSIS USING SOFTWARE: Figure 1 PLAN
