1. Guided By: Presented By: Mrs. SWAYAM SIDHA DASH KALI PRASAD RATH Dr . MONIKA MOHANTY Registration Number:-2101109050 Sec-A 3 rd Year B .Tech , Department of Civil Engineering, PARALA MAHARAJA ENGINEERING COLLEGE HIGH RISE BUILDING CONSTRUCTION

2. CONTENTS:

3. INTRODU C TION : Emporis standards National Building Code (Part 4) International Conference on fire safety United State General Laws Multi story structure (35 to 100 m , 12 – 39 floors) High rise being higher than 70 ft (21m) Any Structure , height have serious impact on evacuation Building Height > 15m

4. Demand For High-Rise Buildings: Scarcity of land in urban areas Increasing demand for business and residential space Economic growth Technological advancements Innovations in structural systems Desire for aesthetics in urban settings Concepts of city Skyline Cultural significance and prestige Human aspiration to build higher

5. Shallow foundation System Deep foundation System Types of foundation Spread foundation Raft/Mat foundation Pile Pile walls Diaphragm wall Caissons

6. Spread foundation Spread footing may be built in different shapes and sizes to accommodated individual needs such as the following: Square spread Footings Rectangular Spread Footings Circular Spread Footings Continuous Spread Footings Combined Footings Ring Spread Footings Raft Foundation A foundation system in which essentially the entire buildings is placed on a large continuous footing. It is a flat concrete slab, heavily reinforced with steel, which carries downward load of the individual columns or walls. Raft foundation are used to spread the load form from a structure over a large area, normally the entire area of the structure.

7. Square Spread Footings Rectangular Spread Footings Support a single centrally located column Use concrete mix 1:2:4 and reinforcement The reinforcement in both axes are to resist/carry tension loads Useful when obstruction prevent construction of a square footing with a sufficiently large base area and when large moment loads are present

8. Circular Spread Footing Continuous Spread Footing Are round in plan view Most frequently used as foundation for light standards, flagpoles and power transmission lines. Used to support bearing walls

9. Combined Footing Ring Spread Footing Support more than one column Useful when columns are located too close together for each to have its own footing Continuous footing that have been wrapped into a circle Commonly used to support the walls above ground circular storage tanks

10. Deep Foundation: Extend several dozen feet below the building Piles Piers Caissons Compensated Foundation Load can be transferred by PILE to the ground by 2 way :- End Bearing Piles Friction Piles

11. DESIGN CONSIDERATION: There are 3major factor to consider in the design of all structure : 1.Strength 2.Rigidity 3.Stability CONSTRUCTIONS MATERIALS:

12. Construction Method and Techniques: Slip Form Jump form Climbing Formwork Table Form/ Flying Form Column System Formwork Tunnel Form System Constraints Once the goal criteria and additional goal options are listed, many constraints must be determined and documented . These constraints many include the following: Performance limitation Available capacity Available space Available utility sources Available infrastructure Building architecture

13. Structural Concern: The primary structural skeleton of a tail building can be visualized as a vertical cantilever beam with its base fixed in the ground .The structure has to carry the vertical gravity loads and the lateral wind and earthquake loads. Gravity loads are caused by dead and live loads. Lateral loads tend to snap the building or topple it. The building must therefore have adequate shear and bending resistance must not lose its vertical load carrying capability The skyscraper pushes down on into the ground . But when the wind blows, the column in the windy side stretch apart. And the columns on the other side squeeze together.

14. Classification of Tall Building Structural System: Can be classified based on the structural material used such as concrete or steel Structural systems of tall buildings can also be divide into two broad categories 1) INTERIOR STRUCTURE 2)EXTERIOR STRUCTURE The classification of lateral load-resisting systems is based on their distribution over a building. Interior structures have major components in the interior, while exterior structures have minor components at the perimeter.

15. ADVANTAGES : Plasticity Easily Availability Easy in Casting Non corrosive Can be cast in situ DISADVANTAGES: Cost of form Dead weight Difficulty in pouring

16. CONCLUSION: The construction technique and the requirement for the High Rise Building is most important for the proper management and for the strength of the building It is not a good building if there is not a good structure The structure corresponds to the material that are used for the construction The uses of the materials that are required for the construction of High Rise Building and the management of the waste product and the treatment of the waste water for the reuse is most important The High Rise Building possess of there specific development background, Along the rapid grow of people, there a lot of demand of the High Rise Building and also the requirements in the design The construction will start only if there is a proper planning and with the quality control method. Without planning it will seems like the man without leg
