Question
A large carport has footing loading as shown on Figure As 1 when normal maximum wind force id applied.
a) Using the stability formula specified chapter two of the lecture notes. Determine the total weight W required (this include the weight of soil). Soil density = 19 KK/m3.
b) Determine the minimum weight of concrete. This should be at least = WL↑ + 0.8 DL↓ /0.8.
c) Calculate the actual weight of concrete.
d) Find the total weight mobilised, i.e. Concrete + soil.
The roadway is to be widened which will require a slope face cut at a steeper angle. Assume zero cohesion along the joints. What engineering parameter must the joint surfaces possess (magnitude) to be stable
Knowing that each member has a 2 3 4-in. rectangular cross section and that each pin has a 12 -in. diameter, determine the maximum value of the average normal stress (a) in member BE, (b) in member CF.
