3. What is SHEAR WALL?
■ Structural member used to resist lateral
forces
■ Provide strength and stiffness to control
lateral displacements
■ Minimum thickness - 150mm, Maximum
thickness - 400mm in high rise buildings
 Vertical plate-like RC walls
 Start at foundation level and are continuous
throughout the building height
Why SHEAR WALL is
provided?

5. Classification SIMPLE RECTANGULAR TYPE
COUPLED WALLS
RIGID FRAME SHEAR WALLS
FRAMED WALL WITH INFILLED FRAMES
COLUMN SUPPORT SHEAR WALLS
CORE TYPE SHEAR WALLS

6. SIMPLE RECTANGULAR TYPE
COUPLED WALLS
RIGID FRAME SHEAR WALLS
FRAMED WALL WITH HCT INFILL
COLUMN SUPPORT SHEAR WALLS
CORE TYPE SHEAR WALLS stronger and more ductile
wall is provided monolithically
between two column

7. SIMPLE RECTANGULAR TYPE
COUPLED WALLS
RIGID FRAME SHEAR WALLS
FRAMED WALL WITH HCT INFILL
COLUMN SUPPORT SHEAR WALLS
CORE TYPE SHEAR WALLS
Two structural walls are
joined together by
relatively short spandrel
beams

8. SIMPLE RECTANGULAR TYPE
COUPLED WALLS
RIGID FRAME SHEAR WALLS
FRAMED WALL WITH HCT INFILL
COLUMN SUPPORT SHEAR WALLS
CORE TYPE SHEAR WALLS
- Provide greater lateral
rigidity
- Can build up to 20-25 floors
- Composed of braced panel
(to counter the effect of
lateral loads)

9. SIMPLE RECTANGULAR TYPE

RIGID FRAME SHEAR WALLS
FRAMED WALL WITH HCT
INFILL
COLUMN SUPPORT SHEAR WALLS
CORE TYPE SHEAR WALLS
Reinforced concrete (RC) frames with
hollow clay tile (HCT) infill walls
carbon fiber–reinforced polymer (CFRP)
fabrics

10. SIMPLE RECTANGULAR TYPE

WALLS
CORE TYPE SHEAR WALLS

11. SIMPLE RECTANGULAR TYPE
COUPLED WALLS
RIGID FRAME SHEAR WALLS
FRAMED WALL WITH HCT INFILL
COLUMN SUPPORT SHEAR WALLS
CORE TYPE SHEAR WALLS
- lateral & gravity loads are supported by core
- Eliminates column & bracing elements
- Core wall is provided around staircases or
lift wells

13. LOCATION OF SHEAR WALL IN A BUILDING
■ Located symmetrically to avoid ill effect of twisting
■ Can be located at exterior or interior
■ More effective when located along exterior perimeter
of building

14. Design Provision:
■ Step- 1: Review of the layout
■ Step-2: Determination of various loads
■ Step- 3: Estimation of earthquake design
force
■ Step-4: Analysis of the structural systems
■ Step- 5: Design for flexural strength
■ Step- 6: Design for shear strength
■ Step- 7: Detailing of reinforcement

15. BEHAVIOUR UNDER SEISMIC LOADING:
■ Depending on the height to width
(H/D) ratio , a shear wall may be
behave as a slender wall a squat wall
or a combination of two.
■ Squat wall show significant amount
of shear deformation as compared to
bending deformation.
■ In slender wall primary mode of
deformation is bending. Shear
deformation are small and can be
neglected.

17. Advantages
1. Energy dissipation capability & high
stiffness.
2. Provide strength & stiffness in direction
of orientation
3. Reduces lateral sway
4. Easy construction & implementation
5. It is more resistant to Earthquake.
6. Efficient in terms of construction cost
Conclusion
Effective building element in
resisting lateral forces
Larger stiffness
Damages can be minimized
