The paper presents the results of laboratory experiments carried out on eight clay brick masonry wallettes of two types under cyclic compressive loading. Based on the results, the failure envelopes were determined, presented and discussed, as were common points stressstrain relationships for both series of specimens. The analytical description of the kinetic of stiffness degradation (with proposed appropriate formulae and experimentally determined parameters) was elaborated and proposed.

W pracy zaprezentowano wyniki badań 8 murów (dwóch serii) z cegły ceramicznej pełnej poddanej cyklicznej sile ściskającej. Zależność naprężenie – odkształcenie zostało omówione dzięki znajomości krzywej punktów wspólnych i obwiedni z badań cyklicznych. Podjęto próbę analitycznego opisu procesu degradacji sztywności muru.
