PROBLEM 1: Design a square footing that supports a 400 mm x 550 mm column. The column carries a service dead load of 980 KN and a service live load of 1110 kN. Use the following properties given: fc' = 30 MPa fy = 275 MPa depth of footing, 1.60 m Unit wt. of soil, 17 kN/m3 Allowable soil bearing capacity, 300 kPa Concrete clear cover, 70 mm Diameter of bar, 25 mm Unit wt. of concrete, 24 kN/m3
Question 8(a)
Calculate the soil bearing capacity of a soil under a strip footing at a depth of 2.5 ft and 4 ft wide. Angle of friction: 30° Unit weight of soil: 133 lbs/ft3 Factor of safety: 3.0 Cohesion: 0
Two footings, one circular and the other strip, are founded on the surface of a purely Cohesionless soil. Diameter of the circular footing and width of strip footing is same. Then, the ratio of ultimate bearing capacity of circular to strip footing is:
subject
Figure (a) shows the cross section of square footing of 3 m x 3 m. The soil properties are shown in the figure. i) ii) Determine the load Q that the footing can carry. Use the factor of safety (FOS) of 2.5. During rainy season, groundwater level increased to the soil surface. Based on this condition, calculate the new FOS and justify whether the existing footing is able to carry the same amount of load as calculated in (a) Not drawn to scale 1.6 m 0.4 m Water level 3m Q Soil properties Yd=18.3K³ Ysat = 21 kN/m³ = 30°
The underlying soil is a well-graded sand with c′ = 0, f′ = 36°, g = 126 lb/ft3, with a verydeep groundwater table. Using LRFD, design a rectangular footing to meet the ultimate limitstates using a resistance factor of 0.45. Assuming the average CPT tip resistance of the sand is300 kg/cm2, check to see if your design meets serviceability limits. Adjust the design as needed.
:Answer with "True" or "False" for the following statements. 1- For all modes of failure heaving of soil will occurs on both sides of footing at final collanse 2- General shcar failure will exist when the relative density of sandy soil is less than thirty percent 3- For all types of soils the ultimate bearing capacity is increased with the increasing in size of footing. 4- When the relative density of sandy soil is more than (67%) there is no need to take into consideration the effect of soil compressibility in the calculation of ultimate bearing capacity. 5- For the footings that loaded eccentrically, only the part of the footing that is symetrical with regard to the load is used to determine bearing capacity by the useful width method.
Estimate the immediate settlement of a concrete footing 1.5m*1.5m in size founded ata depth of 1m in silty soil whose modulus of elasticity is 90kg/cm2 .The footing isexpected to transmit a unit pressure of 200kN/m2Assume, µ = 0.35, If = 0.82 for a rigid footing.
A proposed office building will include an 8 ft 6 in square, 3 ft deep spread footing that will sup-port a vertical downward service load of 160 k. The soil below this footing is an overconsolidated clay with the following engineering properties: Cc /(1 + e0) = 0.10, Cr/(1 + e0) = 0.022,sm′ = 4,500 lb/ft2and g = 113 lb/ft3 . This soil strata extends to a great depth and the ground-water table is at a depth of 50 ft below the ground surface. Determine the total settlement of this footing.
