Final answer:
The major load carrying members in deck construction are joists, beams, and posts. Joists support the deck floor, beams support the joists, and posts support the beams.
Step-by-step explanation:
The major load carrying members in deck construction are joists, beams, and posts.
Joists are horizontal structural members that support the deck floor. They are typically made of wood or steel and are spaced apart to distribute the weight of the deck evenly.
Beams are horizontal or sloping structural members that support the joists. They are usually made of wood or steel and provide additional strength to the deck.
Posts are vertical structural members that provide support for the beams. They are usually made of wood or steel and are placed at regular intervals along the edge of the deck.
