Cpccbc4010A Assessment 1
Question 1
a) What is meant by a load path?
A load path is the transfer of loads and forces from the through the building to the bottom of the building, following the most direct structural path.
b) Sketch an example of a load path from roof cladding to foundation for a brick veneer dwelling with trussed roof. Label clearly and indicate the load path with arrows. Diagram 1.b

Question 2
Outline the roles of the following people in the design of a building:
Architect: design the building and supervise construction and cost.
Service engineer: design layouts and requirements for Environmental, Heating, ventilation, air conditioning, electrical and hydraulic
Draftspersons: draws the plans
Question 3
Give definitions (in your own words) of the following and give an example of each:
A load is a force which are applied to a structure in any direction
Support reaction is how much load force there will be needed on a part of the structure to keep the load supported.
Ductility when a material is not rigid and can move when loads are applied to them will deflect and stretch without failing.
Tensile strength is measured in mega Pascals it is the strength of the materials against failure under pulling of the load.
Pressure is the force of the load over an area.
Structural elements are the building materials that support the building from falling down e.g. columns, bracing ply, wall cladding.
Question 4
Imagine you are at a party. There are lots of people packed into a room, and you estimate that the average mass of each person is 70 kg, and the average space that each person is occupying measures about 500 mm by 500 mm.
a) Express this live load in kPa. Convert this to a load in kN/m on a single joist (joist spacing 450mm). 70kgx9.8m/s2 = 686
.5mx.5m = .25 = 2744 Pascals = 2.744 kPa 2.744 kPa x .5m
