The document outlines the design and structural analysis of tall buildings using the ETABS software. It includes specifications such as dimensions, materials, and design codes, as well as a step-by-step guide for modeling in ETABS. The document emphasizes the importance of accurate data input and the application of different load types in high-rise building analysis.
ANALYSIS AND DESIGN OF HIGH RISE BUILDING BY USING ETABS
- 2. INTRODUCTION • From a structural engineer's factor of view the tall constructing or high upward thrust constructing (HRB) may be outlined in concert that, with the inside the structural type. • The growth in latest multi storeyed constructing development, which began in late nineteenth century, is meant for essentially the most part for industrial and residential features.
- 3. INTRODUCTION • Tall buildings are the fundamental evolved engineered structures considering there are a few conflicting necessities and problematic constructing techniques to integrate • In these day’s tall constructions are getting extra and additional slim ensuing in the hazard of further sway as compared with earlier high- rise structures.
- 4. ETABS • The innovative and revolutionary new ETABS is that the final integrated software package for the structural analysis and style of buildings.
- 5. ETABS • ETABS offers unmatched 3D object primarily based modeling and visualization tools, blazingly quick linear and nonlinear analytical power, subtle and comprehensive style capabilities for a wide-range of materials, and perceptive graphic displays, reports, and schematic drawings that enable users to quickly and simply decipher and perceive analysis and style results.
- 6. ETABS • ETABS provides an unequaled suite of tools for structural engineers designing buildings, whether they are working on one-story industrial structures or the tallest commercial high-rises. A. Modeling of Structural Systems B. Loading, Analysis, and Design C. Output, Interoperability, and Versatility
- 7. STATEMENT OF PROJECT • A notion of 24.14m×20.627m plan is taken into idea having 16×12 bays on each the sides. • The excessive rise constructing (HRB) of 30 stories inside which flooring to flooring top is taken as 3m. • Ground to ground peak is 3.5m for all of the models.
- 8. CODES • IS-456:2000:DESIGN CODE FOR RCC STRUCTURES • SP-16 : DESIGN CODE FOR COLUMNS • IS-875(PART 1) : FOR DEAD LOADS • IS-875(PART 2) : FOR IMPOSED LOADS • IS-875(PART 3) : FOR WIND LOADS • IS1893:2002 : FOR EARTHQUAKE LOADS
- 9. MATERIAL DETAILS • GRADE OF CONCRETE : M-30 • TYPE OF STEEL : Fe-500 • BRICK MASONARY : FIRST CLASS
- 10. GEOMETRICAL DETAILS • Depth of foundation : 3 Mts, • Floor to Floor height : 3 Mts, • Ground floor hright : 3.5 Mts, • Slab thickness : 120 mm • External wall thickness : 230 mm • Internal wall thickness : 125 mm
- 11. MODELING IN ETABS STEPS 1. Open ETABS program. 2. Check the units of the model in the drop- down box in the lower right-hand corner of the ETABS window click the drop-down box to set units to KN-m.
- 12. 3. Click the File menu > New model command
- 13. 4. The next form of Building Plan Grid System and Story Data Definition will be displayed after you select NO button.
- 14. 5. Define the design code using Options > Preferences > Concrete Frame Design command
- 15. 6. This will Display the Concrete Frame Design Preference form as shown in the figure.
- 16. 7.1. Click the Define menu > Material Properties
- 17. 7.2 Add New Material or Modify/Show Material used to define material properties
- 18. 8. Define section columns and beams using Define > Frame section
- 20. To define a slab as membrane element and one way slab define using special one way load distribution
- 21. 10. Generate the model Draw beam using Create Line Command and draw column using Create Column command
- 22. 11. Slab is created using 3 options in which 1st draw any shape area, 2nd draw rectangular area and 3rd create area in between grid line
- 23. 12. Model showing plan 3d view of high rise building without bracings in linear analysis
- 24. Model showing plan 3d view of high rise building with bracings in linear analysis
- 25. Model showing plan 3d view of high rise building without bracings in linear analysis
- 26. Model showing plan 3d view of high rise building with bracings in linear analysis
- 27. 13. Define various loads (Dead load, live load, wind load, Earthquake load)
- 28. 14. Dead Load: self weight multiplier is used 1 to calculate dead load as default. Live load or any other define load 1st select the member where assign this load than click the assign button.
- 29. 15. Assign point load and uniform distributed load Select assigning point or member element than click the assign button
- 30. 16. Assign support condition Drop-down box in the lower right-hand corner of the ETABS window, Select only bottom single storey level to assign fixed support using assign > Joint/Point>Restrain (Support) command
- 31. 17. In building, slab is considered as a single rigid member during earthquake analysis. For that, all slabs are selected first and apply diaphragm action for rigid or semi rigid condition.
- 32. 18. Mass source is defined from Define > mass source command
- 33. LOADS ON MODELS
