Calibration of Partial Safety Factors of Sample Masonry Structures

Abstract

Technological progress in masonry structures has resulted in the creation of competitive solutions, which force the need for an ever deeper recognition of this type of structure. Masonry is a composite with heterogeneous strength properties. Therefore, the most appropriate way to accurately describe the behavior of the masonry structure under the influence of the working load are experimental research and their statistical and probabilistic analysis. This article presents a series of experimental tests carried out on real masonry structures. The results of the experiments were subjected to static evaluation, determining the most important parameter in the probabilistic analysis—the coefficient of variability of strength. The variability obtained in the experimental studies was used to determine the safety of the structure in the probabilistic method. Achieved values of coefficients of variation and safety coefficients proved to be satisfactory and adequate to the emerging technological progress in the production and embedding of masonry components.

Construction and Building Materials: Masonry Structures and Reinforced Concrete Structures

“…The tests on elements and structures are presented in three papers [3,9,21]. In the paper [3], Grzyb and Jasi ński analysed the behaviour of shear walls in masonry buildings subjected to monotonic loading.…”

“…Based on changes in angles of shear deformation and behaviour phases, the authors proposed an empirical approach to distribution loads into individual shear walls. Tests on masonry columns under compression are presented in the paper [9]. The subject of the research included two series of slender walls made of solid brick and autoclaved aerated concrete (AAC) masonry units.…”

“…Zięba, Skrzypczak, and Buda-O żóg, in the paper [9], dealt with the aspect of reliability of masonry structures. Based on the results from testing compressed columns made of solid bricks and masonry units made of autoclaved aerated concrete (AAC), the authors conducted a probabilistic analysis and suggested their own safety factors γ M for masonry.…”

“…The numerical validation of the model of wall connections was proposed only in the paper [21]. Tests on component elements [2,4,5,7,9,11,14,21], and on repairs and strengthening of constructions [10,13,19,24] were conducted for both reinforced concrete and masonry structures.…”
