What is the anchorage requirement for a wood sole plate?

The anchorage requirement for a wood sole plate provides essential guidance for ensuring structural integrity, especially in preventing lateral movements attributed to wind or seismic activity. The correct choice indicates that there needs to be a minimum of two bolts that are at least 1/2 inch in diameter or larger, which gives ample strength to withstand stress.

Having these bolts placed no more than 12 inches from each end of the wood sole plate ensures that the connection to the foundation is secure at critical points, effectively distributing loads along its length. Furthermore, spacing these bolts a maximum of six feet apart allows for adequate anchoring while not overly reducing the shear resistance provided by the fasteners. The requirement for the bolts to be inserted at least seven inches into the concrete adds to the effectiveness of the anchorage, minimizing the likelihood of pull-out failure.

These factors combined help to ensure that the structure will perform safely and meet building code requirements. The emphasis on both the quantity and specifications of the bolts reflects the importance of adequate fastening in construction to provide stability and durability over time.
