USING THE ONTARIO BUILDING CODE TO SOLVE THESE QUESTIONS ARCH1013 Architectural Engineering

1. Calculate the minimum width and thickness of footings required to support walls of Cassidy House Elevation B. (1.5/4).

a)Footing width and thickness of exterior walls, if the floor joists span less than 4.9 m:
Cassidy is a Two-storey house, minimum thickness of footing (Table 9.15.3.4.)=
Two storeys of Brick veneer (9.15.3.5.) =
Adjusted Footing width for Cassidy House =
Thickness (9.15.3.8.)=

b)Assume that the house has a load bearing masonry interior wall that is 150mm thick supporting both first and second storey. Determine the minimum width and thickness required of its footing:
Min. thickness of footing for an interior wall that supports two floors (Table 9.15.3.4) =
Adjust for two storey of masonry wall (9.15.3.6.) =
Thickness =

2. Answer the following questions based on foundations details of Cassidy Elevation B. (1.5/4).

a)What is the maximum height of finished ground the foundation wall can support, if it is 2.5m high?
Table 9.15.4.2.A, Construction Notes

b) If you were to build this wall with 190mm thick ICF, what is the minimum vertical reinforcement required, using the height of foundation wall and ground found in earlier questions?
Table 9.15.4.B.

c) If you were to build this wall with unreinforced concrete blocks, what is the minimum thickness of the foundation wall?
Table 9.15.4.2.A.

3. Calculate the footing width of an external wall of a three storey wood frame brick veneered house. Assume it supports joists spanning 11.5m on first and second floors and 10m on third floor. (1/4)

9.15.2.4.B: use the formula;
W = w (εsjs/ storeys x 4.9)

If anyone has any Idea on how to do this or has any Architectural background please explain to me!
