RC Frame Systems Explain

Question 1

A structural system with the following features:
- An essentially complete space frame that provide support to gravity loads,
- Resistance to lateral load is provided by shear walls or braced frames and moment-resisting frames. The moment-resisting frames shall be designed to independently resist 25% of the design base shear.
- Both space frame and moment-resisting frames shall be designed to carry the design base shear according to their rigidities considering the interaction of the dual system at all levels

Answer 1

Dual Systems

Question 2

Structural system that relies on cantilevered columns for lateral resistance.
10 m limit in zone 4

Answer 2

Cantilevered Column System

Question 3

utilizes a complete 3-D space frame to support gravity loads and shear walls to resist lateral loads
The main lateral load resisting system consists of reinforced concrete shear walls forming the elevator core (central core formed by the elevators and stairs in the building), and additional walls located elsewhere in the building as required.

Answer 3

Frame/shear-wall hybrid system

Question 4

These buildings are generally characterized by a symmetrical plan of square, circular, or hexagonal shape with a centrally located elevator core.

Answer 4

Frame/shear-wall hybrid system

Question 5

T or F
The interaction of the frame and shear walls is essential for limiting lateral deformations due to wind and earthquake loads.

Answer 5

True

Question 6

a structural component provided to multi-storeyed or tall buildings or ordinary buildings in high wind velocity areas

Answer 6

Shear Wall

Question 7

These walls usually begin from the foundation level, along the length and width of buildings.

Answer 7

Shear Walls

Question 8

Shear Wall thickness can be above ____ mm or below ___ mm in tall buildings; they are like vertical-oriented wide beams that carry the earthquake load towards the foundation.

Answer 8

150; 400

Question 9

provide large strength and stiffness to buildings in the direction of their orientation.

Answer 9

Shear Walls

Question 10

Why it is provided?
- This wall resists the lateral loads that are imposed on the structure due to wind, earthquake, or sometimes due to hydrostatic or lateral earth pressure.
- Shear wall buildings are a common choice in many earthquake-prone countries.
- They are efficient in reducing construction costs.
- Also reduces earthquake damage in structural and non-structural elements such as glass windows and construction materials.
- Buildings with shear walls have shown very good performance during earthquakes in high seismic areas.

Answer 10

shear wall

Question 11

where it is provided?
- Usually, these walls stay at the height of the entire building; however some walls are closed to the road front or basement level to permit for industrial or parking areas.
- Sometimes, the wall structure is symmetric with respect to at least one axis within the plan.
- Usually, wall reinforcement consists of two layers of reinforcements distributed through the length of the wall.
- Also, vertical reinforcement bars are offered near the door and window openings on the wall end zones.

Answer 11

shear wall
