“…The same data were used by Eibl et al [51] to define another simple model, which proposed exponential unloading curves and linear reloading curves. Similar formulations, representing the curves with exponential or polynomial functions are also included in [52][53][54] for different types of masonry. None of the former models considered the case of partial unloading-reloading.…”

This research presents an experimental programme on the mechanical characterization of masonry under monotonic and cyclic uniaxial compression. Two different types of standard specimens, running bond walls and stack bond prisms, were built using handmade clay bricks and hydraulic lime mortar. The experimental results are compared and discussed in terms of strength, stiffness and deformability. It was observed that the two specimen types provided very similar results on both strength and stiffness. Cyclic loading tests carried out on a set of samples provided new experimental evidence on the stiffness degradation, loss of load carrying capacity for increasing irreversible compressive strains and energy dissipation. The paper presents eventually a thorough discussion about the comparison between the obtained experimental results with available predictive models for strength, stiffness and fracture energy of masonry under monotonic and cyclic compression loading.

“…The model is composed of simple polynomial functions derived based on the statistical evaluation of cyclic test data. During the development of these polynomials, an approach, which was also used by Naraine and Sinha [34], Nazar and Sinha [35], and Ispir and Ilki [36] for modeling the stress-strain curves of different types of masonry materials, was used. In this approach, the loading and unloading curves are transformed to a normalized coordinate system, and a polynomial is fitted on this coordinate system.…”

External confinement of columns of existing reinforced concrete buildings using fiber-reinforced polymer (FRP) composites can significantly increase the ductility and compressive strength of structural members against seismic actions. Therefore, knowledge on the behavior of FRP confined concrete/reinforced concrete members under cyclic stresses is vitally important for realistic prediction of seismic performance of retrofitted structures. In this study, available experimental data on the cyclic stress-strain behavior of FRP confined concrete/reinforced concrete members are evaluated in a comparative manner, and accuracy of several stress-strain models proposed for FRP confined concrete is discussed in terms of prediction of the skeleton curves, as well as the unloading-reloading branches of the cyclic stressstrain relationships of the tested samples. Furthermore, a new model is proposed for the prediction of unloading and reloading branches based on the cyclic tests carried out specifically for this purpose. The predictions of the proposed model and two other available models proposed for cyclic loading are compared with experimental data, and a satisfactory agreement is observed between the predictions and experimental data.

“…Several experimental studies have been performed regarding compressive constitutive models [1][2][3][4] and strength prediction models of brick and tuff masonry, which are useful as references for establishing prediction equations of failure mechanisms, stress-strain behavior, and strength of Tibetan rubble stone masonry. Common empirical constitutive models of masonry include polynomial type, rational fraction type, and two-step type models.…”

Basic mechanical properties of Tibetan rubble stone masonry, a unique architectural structure in western China, may affect the bearing capacity of architectural structures. In this study, a compression test was carried out on a Tibetan rubble prism to investigate its failure mechanism and stress-strain characteristics under uniaxial compression. Based on the experimental results, we obtained two simple compression constitutive models for Tibetan rubble stone masonry, established equations applicable to predicting the compressive strength of Tibetan rubble stone masonry, and obtained a relationship between compressive strength and the elasticity modulus through a regression analysis.
