What framing members should be installed when joists run parallel to a wall to transfer inward forces against a wood foundation?

The correct framing members to install in this scenario are blocking. Blocking refers to short pieces of lumber that are placed between joists or studs to provide additional support and stability. When joists run parallel to a wall, blocking is essential to transfer inward forces against a wood foundation effectively. It helps distribute the weight and resist lateral movement, enhancing the structural integrity of the frame and preventing potential issues such as racking, where the walls lean or become misaligned.

Blocking also serves to tie the joists together, which helps maintain the alignment of the framing structure while ensuring a more rigid assembly. The use of blocking is vital in areas where extra support is needed, especially in situations where joists must endure various loads and forces.

Other options, like headers, joist hangers, and bracing, serve different purposes within framing. Headers are typically used above door and window openings to support vertical loads, joist hangers provide a means to fasten joists to beams or ledger boards, and bracing is generally employed to add lateral stability to walls or frames. While each of these components is important in framing, they do not specifically address the need to transfer inward forces in the context described.
