The development of a new method for testing the lateral load capacity of small-scale masonry walls using a centrifuge and digital image correlation

A new method is presented for the manufacture and testing of 1/6th scale masonry wall panel specimens using a centrifuge to correctly model self-weight. The test procedure allows application of either uniform lateral load using an air bag or non-uniform hydraulic loading. A novel approach has been taken to measure deflections during testing using digital image correlation and has proved successful. Results of three initial uniform lateral loading tests of specimens manufactured from autoclaved aerated cement blocks and M2 strength class mortar are detailed. The experimental failure loads compared reasonably well to values calculated using yield line analysis.
