Which load is not considered while designing slab?
As per IS 456:2000 Earthquake load (Seismic load) and Wind load is not considered simultaneously in design.
Why do we use steel in making RC?
It is because the two materials bond together very well with no slippage and thus act together as one unit in resisting the applied loads, apart from few other important properties of steel. The tensile strength of steel is approximately equal to 100 – 140 times the tensile strength of plain concrete mix.
What is special consideration in steel design?
Factors to be considered in the design of steel structures. All the members in the structure should have adequate strength, stiffness and toughness to ensure proper functioning during service life. Members should have adequate strength, stiffness and toughness to ensure proper functioning during service life.
What decides between steel and RCC structure?
RC structures are highly brittle in nature. These type of structure have less resistance to dynamic loads like earthquakes and wind. Steel structures are ductile in nature thus increasing their resistance to dynamic loads. RC structures have low load-carrying capacity compared with steel structures.
What are the types of load to be account for steel design?
The types of loads acting on structures for buildings and other structures can be broadly classified as vertical loads, horizontal loads and longitudinal loads. The vertical loads consist of dead load, live load and impact load. The horizontal loads comprises of wind load and earthquake load.
Which of the following loads is not included under imposed load?
These loads are anticipated loads due to self weight, imposed load, snow, wind load, etc. 7. Which of the following is not included in imposed load classification? Explanation: Imposed loads are gravity loads other than dead load and cover factors such as occupancy by people, stored material etc.
Why steel is used as reinforcement bar?
Steel reinforcement bars or rebars are used to improve the tensile strength of the concrete, since concrete is very weak in tension, but is strong in compression. Steel is only used as rebar because elongation of steel due to high temperatures (thermal expansion coefficient) nearly equals to that of concrete.
What are the disadvantages of steel reinforcement?
Cons (Disadvantages) of using Steel Rebar:
- High Cost: Steel is expensive and considerably increases the cost of structure.
- High Temperatures: Steel show tendency to melt in extremely high temperatures.
What is designing steel structure?
Steel design, or more specifically, structural steel design, is an area of structural engineering used to design steel structures. These structures include schools, houses, bridges, commercial centers, tall buildings, warehouses, aircraft, ships and stadiums.
Is code for steel structure?
IS: 2062 – specifications for steel for general purposes.
Why steel structures are not used in India?
As per India’s climatic conditions, Steel structures are not suitable for houses. Steel buildings create more heat inside the spaces. Also, Steel is a good conductor of heat and so touches off materials in contact and often may cause fires. Hence, steel structures also require extra fireproofing treatment.
Is steel structure better than concrete?
Although steel takes up the tensile stresses, the concrete in the tensile zone develops minute cracks. The load carrying capacity of such concrete sections can be increased if steel and concrete both are stressed before the application of external loads.
