Abstract: Tests on half scale models of masonry walls built on point supported continuous beams show that the structure behaves like a composite diaphragm girder, with the foundation beam acting as a tension tie. The reactions on the interior supports are considerably smaller than those of ordinary beams and, as a result, the external moments are positive throughout the length of the wall. The main cause of failure is crushing of masonry above the supports. Vertical stanchions at the supports increase the failure load but do not change the mode of failure that occurs after separation between stanchions and masonry through vertical cracks. An approximate method of design, disregarding forces at the wall-beam boundary, was found to yield reliable results, especially with regard to the safety factor against failure.
