A 1.40m x 1.80m footing is used to support a total factored load of 750 kN. The footing thickness is 325 mm and the column size is 300mm x 300mm. Use effective steel covering of 75mm, fc’ = 21MPa and fy = 276 MPa. (See Figure 6)

pls only attempt if you understand and are able to provide a proper complete answer

I need correct solution Solution in chegg was incorrect So please provide correct solution

A 3.4 m square footing is proposed to be used to support a 353 mm x 630 mm RC column loaded with 634 kN dead load and 853 kN live load. The bottom of the footing is 2.3 m below the ground. Assume soil weighs 19 kN/m³ and the allowable soil bearing pressure is 314 kPa. The thickness of the footing is 431 mm. f = 21 MPa and f = 420 MPa. It is to be reinforced with 20 mm diameter. Use 24 kN/m³ as the unit weight of concrete. Note: For two-way shear, use an effective depth measured from the top of the footing until the top of the bottom-most bar (d;) What is the ratio of the Demand Shear Force and the Capacity in Two Way Shear? (Vu/phiVn) Answer is 1.5881 (Complete Solution)

A combined rectangular footing is composed of exterior column 450 mm x 600 mm and interior column 600 mm x 600 mm. The 600 mm face of the exterior column coincides the edge of the footing .The depth of the footing is 1.2 m and the bottom of the footing is 1.8 m below the ground. The exterior column carries a service liveload of 510 kN and a service deadload of 790 kN while the interior column carries a service liveload of 820 kN and a service dead load of 1100 kN. Unit weight of soil is 18 kN/m³. Allowable soil pressure is 290 kPa and an additional surcharge of 4.8 kPa placed on the ground surface. Center to center distance of column is 5.5 m. Effective soil pressure at the bottom of the footing is the allowable soil pressure minus the surcharge, pressure due to soil and pressure due to footing.   1. Which of the following most nearly gives the effective soil pressure?  a. 265 kPa b. 271.52 kPa c. 245 kPa d. 255.23 kPa 2. Which of the…

1) Design a rectangular footing for an 16” square corner Column with PDL = 280 kips and PLL = 180 Kips. Make the length of the long side about 1.5 the width of the short side. Fy = 60 ksi F’o= 4000 psi for both, column and footing. Assume the base of the footing is 4'-6" below grade and the depth of the footing is 26". The soil weight is 100 PCF. (Normal weight concrete, No epoxy coating, The Column is reinforced with eight #8 bars.) Need to design for load transfer from the Column to the foating. Need to Show the development length for the dowels. Need to design the bars for footing at both directions. Need to check if the bars fit the footing based on the development legth. Need to show two-way footing Spacing diagram.

Please answer #2 thankyou

Geotechnical engineering -2 (foundation engineering) Solve the following problem with complete solution thank you so much here is 5:09pm i need it by 5:50pm thanks! :)

B Calculate the ratio of the Ultimate Shear Force to Shear Capacity in one-way shear. Consider critical case only. A rectangular footing has dimensions shown and is acted upon by a dead load of 653 kN and a live load of 647 kN. The column dimension is 269x677 mm where the shorter dimension is parallel to B. The thickness of the footing is 442mm. f'c-28 MPa and fy=420 MPa for diameter 20mm bars. A=2.9m and B=4.8m

True or false? For reinforced concrete footings, the size is calculated to satisfy the bending and shear strength of the concrete footing.
