PSAD SITUATION 31: Pile Cap Subject to Combined Axial and Bending | CELE November 2023

CELE Past Board Exam Problem Check out our Review Center: https://www.facebook.com/share/1AC24W... SITUATION 31: A 600 mm x 600 mm column by a 3.6 m square footing on 5 piles as shown. Dimensions are a = 0.60 m and b = 1.2 m Effective depth = 650 mm Diameter of pile = 350 mm Ultimate pile capacity = 280 kN Column Axial Loads: D = 420 kN; L = 360 kN; E = 210 kN Column moment due to earthquake = 160 kN-m The required strength of the footing is based on the following load combination: U = 1.32D + 1.1L + 1.1E 1. Calculate the critical beam shear stress (MPa) at ultimate loads. Φ = 0.75. A. 0.467 C. 0.650 B. 0.512 D. 0.725 2. Compute the ultimate punching stress (MPa). Φ = 0.75. A. 0.388 C. 0.421 B. 0.291 D. 0.325 3. Compute the punching shear (MPa) of the most stressed pile. A. 0.089 C. 0.123 B. 0.178 D. 0.112 Thanks for watching!
