Abstrakt: Several masonry trial wallets were prepared for the testing. The specimens were mounted into a special testing rig which enabled simultaneous uniform compression and cyclic horizontal loading on the top of the tested specimen. There were four hydraulic jacks generating the vertical load which was transmitted to the wall by eight ties and a steel 'hatö on the top of the wall. Horizontal displacement (force) on the top of the wall was introduced from servo-hydraulic MTS actuator of 250 kN capacity. Experimental part involved testing of brick walls for determination of crack pattern development under various combined loadings and testing of brick, sandstone and marly lime stone walls for crack and damage determination by application of NDT methods. Four approaches have been studied and evaluated: i) sonic wave propagation, ii) stress wave propagation, iii) crack pattern development, iv) modal analysis in which also a case study has been accompanied with a related pilot shaking table test of a one leaf masonry model.
