ABSTRACT
The long-term fatigue deterioration process of brick masonry has been studied under quasi-static and high-cycle fatigue loading through a series of small-scale laboratory tests. Stages and characteristics of fracture development under compression and shear were investigated with the help of acoustic emission technique during both static and cyclic loading. Fatigue test results for compression and shear were presented in the form of S-N curves and mathematical models proposed to identify the relationships between stress level and fatigue life. The concept of fatigue limit state and permissibility limit state were discussed and related to masonry arch bridges.
