How do we proceed?

What are the key strength and

stiffness modifiers for timber?

What are the key partial factors for

safety?, For serviceability?

What are Service classes and which

are appropriate for given situations?

Loads/Actions

Partial load factors for: Permanent,

Variable, Accidental

Action combinations: What are the

vital action combination factors and

how do we apply them?

In what way do they differ for: a)

Safety, b) Serviceability

Differences between a connection, a

fastener and a joint

How do we determine load carrying

capacity for simple laterally loaded

fasteners in a connection?

Significance of key design parameters:

density of the timber, embedment

strength, strength of the metal fastener

Significance of the spacing rules and

how they are applied

Situations in which timber may be

weak within connections, and ways of

avoiding/overcoming problems.
