What is one of the main reasons for the variability in the ultimate load Qu for high-rise buildings?
What is one of the main reasons for the variability in the ultimate load Qu for high-rise buildings?
- Unreliable soil parameters (correct)
- The color of the building
- The number of piles used
- The height of the building
How does Figure 1.21a differ from Figure 1.21b in terms of the pile load test arrangements?
How does Figure 1.21a differ from Figure 1.21b in terms of the pile load test arrangements?
- Figure 1.21a anchors the horizontal reaction beam to the ground, while Figure 1.21b uses a kent-ledge.
- Figure 1.21a uses two reaction piles far away from the test pile, while Figure 1.21b uses a kent-ledge to hold the reaction beam.
- Figure 1.21a uses a kent-ledge to hold the reaction beam, while Figure 1.21b uses two reaction piles far away from the test pile. (correct)
- Figure 1.21a uses hydraulic jacks, while Figure 1.21b uses heavy weights.
What is the purpose of using a kent-ledge in the pile load test as shown in Figure 1.21a?
What is the purpose of using a kent-ledge in the pile load test as shown in Figure 1.21a?
- To hold the reaction beam in place (correct)
- To measure soil parameters
- To anchor the reaction beam to the ground
- To apply loads to the piles
