Civil Engineering MCQAE Level Civil Engineering
In post-tensioned prestressed concrete, the bursting tensile force in the anchorage zone is due to:
RCCPrestress Anchorage ZoneMEDIUM
Choose the correct answer
A
Creep and shrinkage
B
The Poisson effect of longitudinal compression spreading laterally
C
Differential temperature
D
Corrosion of wires
Correct Answer
B. The Poisson effect of longitudinal compression spreading laterally
Why is this the answer?
When a large concentrated prestress is applied at the anchorage, the high local compressive stress spreads out over the full cross-section. This spread induces transverse tensile (bursting) forces in the anchorage zone which must be reinforced (using helical reinforcement or links).
