Learning Objectives
Students will learn that:
there are various types of structures, including frame structures, shell structures, combination of frame and shell structures, and structures made from bricks, blocks, stone and composites
each structural type and each building material has its own specific technology
loads and other forces act on structures, including compression, tension, torsion, shear, bending forces
each material has specific chemical and physical properties
materials used to build structures can be reinforced and strengthened in various ways, including using structural sections and composites
equilibrium, moments, centre of gravity and force diagrams are used when designing structures
a safety factor is calculated into the design of structures
materials and components are fixed by temporary and permanent ways by:
electric arc welding
soldering and brazing
riveting
nuts and bolts
adhesives
solid timber is very absorbent at its ends
the end of solid timber has "end grain"
gluing to end grain results in a weak joint
the aim of a wood joint is to:
glue to the sides of timber whenever possible
include a mechanical joint
joints are designed for particular purposes
there are a range of standard joints that are adapted for specific purposes.
