Repeat Problem 9.8 using LRFD for the ULS analysis and assuming the factored ultimate loads range from 300 to 1,500 kN and the resistance factor is 0.45. Service loads range remains as stated in Problem 9.8. Problem 9.8 A proposed industrial building will carry unfactored column loads ranging from 280 to 1,200 kN and service loads from 230 to 950 kN. The allowable settlements are da = 30 mm and dDa = 12 mm. It is supported on a cohesionless sand with f′ = 35° and g = 19.2 kN/m3 . Footings at this site will be at a depth of 2.2 m and the groundwater table is at 5 m. A dilatometer test run at the site has returned the following modulus profile: Prepare both serviceability and bearing capacity design charts, using ASD for ULS analysis. Then, comment on the feasibility of using spread footings at this site. May 14 2022 02:10 PM
