Wood column-and-post end connections must be fastened to resist which type of forces?

Wood column-and-post end connections must be fastened to resist both lateral forces and net induced uplift due to the various loads and actions that structural elements experience in service.

Lateral forces, which can result from wind, seismic activities, or other dynamic loads, exert horizontal pressure on the structural components. Properly fastening the connections is essential to ensure that the columns can effectively transfer these forces to the rest of the building, maintaining structural integrity and preventing failure.

Net induced uplift occurs in scenarios where vertical forces, such as wind uplift or other load conditions, create tension on the columns, effectively trying to lift them away from their bases. Ensuring the connections are designed to withstand uplift is critical in maintaining the stability of the structure, especially in regions with heavy winds or seismic activities.

Thus, both of these forces need to be accounted for in the design and fastening of wood column-and-post end connections to ensure the safety and durability of the building.
