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.

The groundwater table is located at the top of the clay layer, and the submerged density of the clay soil is 0.95 Mg/m³. Consolidation tests performed on 2.20 cm thick doubly drained samples indicate the time for 50% consolidation completed as t50 = 10.5 min for a load increment close to that of the loaded clay layer.
