To determine

The difference between a square footing and continuous footing and the use of each footing.

Explanation of Solution

SQUARE FOOTINGCONTINOUS FOOTING
  • It is generally used to support load on a centrally located column.
  • It is used to support a load bearing wall.
  • It is analogous to a cube.
  • It is analogous to a sidewalk.
  • Commonly provided when the columns are not closely spaced, and the soil regime is homogeneous.
  • They are provided when the row of columns is more closely spaced.
  • It is simple, economical and most widely used footing.
  • It is more economical to use continuous footing than to provide a Square footing in one queue.

Square footing:

They are usually used to hold poles such as large electric poles, porch columns, etc.

Continuous footing:

These are usually used around the basement/foundation of a structure to keep moisture out.

Draw the shear and bending moment diagrams and find the immediate deflection for a simply supported beam of length 20 ft. with the same live load at ½ span and cross-section as the previous problem. Assume a reasonable Modulus of Elasticity and concrete self-weight. Hint: You may look online for typical concrete self-weights and compressive strengths. You may also use the ACI 318 Code equation for the Modulus of Elasticity shown below, and the supplied Design Aids.
Problem 4. A major transmission pathway of the novel coronavirus disease 2019 (COVID- 19) is through droplets and aerosols produced by violent respiratory events such as sneezes and coughs (Fig. 1). For the purpose of providing public health guidelines, we would like to estimate the amount of time it takes for these droplets to settle from air to the ground. The relevant parameters are the settling time (ts), the initial height of the droplets (H), gravitational acceleration (g), density of the droplets (pa), radius of the droplets (R), as well as dynamic viscosity of the ambient air (Pair). Use dimensional analysis and the Buckingham theorem to answer the following questions: 1. Find the independent dimensionless parameters using the table method. Then, express the settling time as a function of the other relevant parameters. Your solution should match the physical intuition that the settling time scales linearly with the initial height. 2. How would the settling change if the…
Question 4 An engineer is assigned to design a 25-stories office building which has a building height of 75 m. Reinforced concrete shear wall system as shown in Figure Q1(a) is adopted to resist the lateral loads. The shear wall is of thickness t = 350 mm and length L = 8.5 m. Use the following data: Young's modulus of concrete E = 28 kN/mm² and the lateral load intensity w = 1.20 kN/m². Assuming the frontal width of the building façade is 15 m is facing the wind force which in turn transmitting the wind force to the shear wall system, estimate the total value of sway A at the roof level. Question 5 For the Shear Wall in Question 4, if the total ultimate gravity load of the building acted on shear wall is 6000 KN, using a partial factor of 1.2 for the wind load, calculate the stress on the extreme right corner of the shear wall at first storey level.
