Determining Masonry Wall Compression Block Depth Value "a"

When determining the Depth of Compression Block value of ‘a’ in a Masonry Wall design based on the equation a = (As * fy)/(0.8 * fm * b) in a RISA-3D model, it is possible to see a small variance in the program results versus a traditional hand calculation using this typical equation. The reason...
