Repeat Problem 11.1 based on LRFD using the following factors: load factor for dead load = 1.25

Question:

Repeat Problem 11.1 based on LRFD using the following factors:

load factor for dead load = 1.25

load factor for live load = 1.75

strength reduction factor on the ultimate bearing capacity = 0.50


Problem 11.1

A continuous foundation is required in a soil where c' = 10 kN/m2, ϕ' = 26°, and γ = 19.0 kN/m3. The depth of the footing will be 1.0 m. The dead load and the live load are 600 kN/m and 400 kN/m, respectively. Determine the required width for the foundation based on allowable stress design with FS = 3, using Eq. (6.10) and Table 6.1.


Eq. (6.10)

1 9u = c'N, + qN, +¥BN, b. 2
