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.

Question 6
If the similar building in Question 4 is designed using rigid
frame method is to be designed to ensure the sway is within
the allowable limit. If the building width is B, and with the
same building height H=75m. Using a rough estimation
method, calculate the maximum allowable
deflection A at the roof level.

- Question IV (30%): A 22 m thick normally consolidated clay layer has a load of 150 kPa applied to it over a large areal extent. The clay layer is located below a 3.5 m thick granular fill (p= 1.8 Mg/m³). A dense sandy gravel is found below the clay. 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. Compute the effective stress in the clay layer at a depth of 16 m below the ground surface 3.5 years after the application of the load.arrow_forward13-3.
