Load and resistance factor design

Load and resistance factors design (LRFD), also known as Limit state design (LSD), refers to the design method used in building engineering. A boundary condition is a condition of a structure where it can no longer meet the relevant design requirements. The condition may refer to the load level or other actions on the structure, while the terms refer to the integrity of the structure, suitability for use, durability, or other design requirements. A structure designed for LRFD is limited to keeping track of all possible actions during its design time and is always ready for use, with the appropriate level of reliability in each boundary condition. LRFD-based construction codes clearly define the appropriate levels of reliability in their instructions.

Question 3. A strip footing is to be used in a clay soil in which the imposed load is 1 MN/m length. The clay layer is 7.0 m thick and overlies a stiff, fractured siltstone. The water table lies at a depth of 2.0 m. a. Determine the footing width based on the long-term allowable bearing capacity (calculated according to the method in the Canadian Foundation Engineering Manual; neglect depth factors) using a factor of safety of 3.0 for a burial depth of 2.0 m. The material properties of the clay are: c' = 15 E = 42 MPa o' = 27° y= 18.5 kN/m³ Ce = 0.40 e, = 0.90 C, = 9.3 x 104m²/day Cu = 25 b. Why would bearing capacity failure likely not govern the design of this structure?
A strip footing carries a load 14506 lbs per foot of length. The footing has a width of 2.3 ft. Determine the increase in vertical stress directly below the center of the footing at a depth of 0.8 ft. Provide your answer in psf, to 2 decimal place. Do not include units in your response.
A 4ft by 4ft spread footing is proposed where the bottom of footing is set 2ft below grade. The column bearing on this footing will impose a load of 180kips. Assuming the subsurface conditions shown below with groundwater 5ft below grade, Use Schmertman’s method to calculate the elastic settlement of the system 6 years after construction is completed, provide a clear sketch and show units and state assumptions.
A rectangular combined footing 8 ft * 20 ft is founded at a depth of 6 ft on a normally con-solidated sand deposit. The sand deposit is approximately 28 ft thick and overlies sandstone. CPT tests indicate the sand is relatively uniform below the proposed footing depth and theaverage tip resistance is 50 tsf. The total service load carried by the combined footing is480 k. Estimate the settlement of this footing.
A 7 foot-square footing is embedded 3 feet below the ground surface and is supported on a clayey sand fill having a total unit weight of 130 pcf. Groundwater is at 8 feet below the ground surface. Consolidated undrained triaxial tests with porewater pressure measurements on three "identical" samples suggest the fill has a drained friction angle of 29 degrees and drained cohesion of 50 psf. What is the allowable bearing capacity for this footing for a factor of safety of 3 AND what is the maximum allowable column load the footing can safely support based on this factor of safety?

A plate-load test was conducted on-site in Cavite in which the soil was found to be clay. PLT was conducted using a circular plate having a diameter of 557 mm. The ultimate load for the test was found to be 554 kN/m2. What should be the maximum allowable load of a footing having a diameter of 2.25 m? Use an FS of 3.98.
4. A subsurface exploration is conducted and it is discovered that the subsurface soils are primarily stiff sandy clays. Given the spacing of some of the columns it is decided that strip footings would best support them. The proposed footing configuration is shown below. Detemine the ultimate loads that can be supported by the footing shown if it is founded at a depth of 3.5 feet below the ground surface.
