Abstract Background There has debate around the way in which the spread of concentrated loads is assumed in masonry codes in masonry. In addition, there is no data available to assess the spread of loads across the joints of storey height AAC elements. Aims The aim was to reconfirm the angle of spread in masonry from a concentrated load and to assess whether this could be applied to storey height elements. Materials and Methods A project took to study the strain development in AAC masonry walls subjected to a single concentrated load. A second project studied walls made from AAC storey height panels subjected to uniform vertical load on one element within a set of 3. Test work was carried out using Digital Image Correlation (DIC). Results The results clearly justified the current design assumptions in Eurocode 6. In the case of storey height elements, the load effects were transmitted across the vertical joint. Conclusions The tests carried out on AAC masonry showed that the spread of concentrated loads is in line of the current recommendations of Eurocode 6. The results justify the when designing with storey height elements, for vertical loading the principals of masonry design can be used.
