Find the difference in the values of w opt and γ d ( max ) between standard and modified compaction tests using Osman et.al correlations.

Question

A5.2- A simply supported beam with the given cross-section, as shown in Figure 2, is subjected to factored uniform load of 50 kN/m. The designer would like to cut-off 2-30M bars where they are no longer required by the design. Determine the cut-off point for 2-30M bars according to CSA 23.3 requirements. Given: Concrete: Normal density with f'c = 30 MPa Reinforcement: Uncoated rebars with fy = 400 MPa Shear reinforcement is in excess of CSA 23.3 minimum requirement: 10M Clear cover to the stirrups: 40 mm Columns: 500 mm x 500 mm 9 m W= 50 kN/m Figure 2 h=600 mm b=500 mm Cross-section As = 5-30M

1. Calculate the ultimate load carrying capacity of the pile tip driven into the soil profile shown below: G.W.T. 45' Qapp Soft Clay: Ysat 100 pcf Cu 500 psf, ou = 0° 平 12' Soil Plug Driven Steel Pipe Pile: Outside Diameter = 2' Inside Diameter = 1'11" Hollow (soil plugged) Note: Pile & soil profile are not drawn to scale Qp = ? Please perform the tip capacity calculation two ways: For the first approach, assume that the total vertical stress at the pile tip is balanced by the weight of the pile. For the second approach, assume that the total vertical stress at the pile tip is not balanced by the weight of the pile (which means you need to include the vertical total stress term). Please compare your answers from these two analyses, examine some of your intermediate-stage calculation results such as the total overburden stress at the pile tip relative to the weight of the pile, and discuss whether or not the commonly used assumption about the total vertical stress at the pile tip is a…

A6.2- Given a simply supported beam with the typical cross-section as shown in the figure below. Assume interior exposure for this beam. The beam properties are summarized below. a) Check if the beam section satisfies the CSA A23.3 cracking control requirements. In your calculations, find f, accurately based on the loading, and compare the results with f = 0.6 fy. b) Find the deflection due to DL+LL at mid-span after 6 years. Given: Concrete: Normal density with f'c = 25 MPa Reinforcement: Uncoated rebars with fy = 400 MPa Shear reinforcement: 10M Maximum aggregate size: 20 mm Clear cover to the stirrup: 30 mm Clear spacing between the bars = 35 mm 35 mm 30 mm m WDL= 20 kN/m WLL= 15 kN/m 抖抖 b=400 mm As = 8-25M Cross-section h=500 mm
