Architectural Structures

Structure architectural expression

• The architectural expression of structure can be
  the key to a successful design solution.
• For simple structural types, the relationship
  between span and depth of members is a strong
  influence.
• With larger spans, architecture and structure
  must integrate efficiently.

Timber in exposed structures
Timber has advantages in exposed structures.

• These include
• Design versatility
• Ease of construction
• Honesty of expression
• High strength to weight ratio
• Economy and
• Enhanced acoustic thermal performance.

Spans over 100 m are possible
