What is the maximum spacing for ties in a block wall used with wood framing?

In the context of block walls used in combination with wood framing, proper spacing for ties is crucial to ensure structural integrity and support. The maximum spacing for ties in this application is typically set at 2 2/3 square feet. This value is established to maintain a strong connection between the masonry and wood framing, providing adequate lateral support and reinforcing the overall stability of the wall assembly.

When ties are spaced too far apart, they may not sufficiently hold the masonry and wood framing together, leading to potential structural issues like cracking or displacement of the block wall. By adhering to the specified maximum spacing, builders can ensure that the wall system functions effectively under various loads and conditions.

Other options present larger spacings which could compromise the structural performance of the assembly, making option C the most appropriate choice according to building codes and best practices in construction.
