This document contains details of a masonry wall design course taught by Jaime Eduardo Cruz in 2016. It lists four students enrolled in the course and analyzes the structural capacity of 7 walls (labeled X1 through X7). For each wall, it calculates the load-bearing area, dead and live loads, and compares the calculated stress to the allowable stress to verify that the wall meets requirements. All walls were found to comply with the allowable stress criteria.
