When is placing construction loads on unabridged joists permitted?

Placing construction loads on unabridged joists is never permitted because unbraced joists lack the necessary support and stability to safely carry loads. These joists are designed to distribute loads evenly when properly braced, and without that bracing, they may deflect excessively or fail under load. This is critical for maintaining the structural integrity of the building and ensuring safety during construction. It is important to adhere to safety standards and guidelines to prevent accidents or structural failures, which underscores why loading unabridged joists should not occur in any situation.
