A 'shear wall' in a multi-storey RC building acts as:
Choose the correct answer
Only carrying vertical floor loads (column alternative)
Vertical cantilever resisting lateral (wind/seismic) loads — provides lateral stiffness and overturning resistance
Only for acoustic insulation
Beam spanning between columns
Correct Answer
B. Vertical cantilever resisting lateral (wind/seismic) loads — provides lateral stiffness and overturning resistance
Why is this the answer?
Shear walls: RC walls acting as vertical cantilevers (fixed at base) to resist lateral loads (wind, seismic). Provide lateral stiffness and strength. Plan layout: symmetric placement to avoid torsion; core walls (lift shafts, staircases) ideal. Design: bending (lateral force × height = overturning moment), shear (base shear), and sliding. IS 13920: special boundary elements at ends of shear wall for ductility.
