An attempt to describe the stiffness degradation of brick masonry subjected to uniaxially cyclic compressive loads

Iwona Galman,

Jan Kubica


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 stress- strain 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.
