Which statement describes a characteristic of Heavy Timber Arch construction?

• A. Joists consist of 2x6s and 1x6 Sheathing
• B. Constructed of large structural members
• C. 2x12 or larger
• D. Adhere to 20 minute burn rule

Answer: (B)

Heavy Timber Arch construction relies on large, solid wood members as the primary load-bearing elements. The arches are formed from thick timbers that transfer loads through compression along curving members, which gives the structure its characteristic strength and fire-resistance. This big-member approach distinguishes it from light-frame methods that use many small joists and sheathing, and from stating a specific nominal size or a fire-exposure rule.
