“…The basic plastic models, that is, Mohr-Coulomb (MC) and DP are widely adopted in constitutive modeling of frictional materials, like concretes, soils, and rocks, when describing the material behavior beyond the elastic range. Since material parameters of MC criterion are easily obtained from standard tests and are logical from the physical point of view, MC criterion is the most common used criterion in geotechnical and structural engineering [13]. MC criterion in threedimensional (3D) stress space can be expressed as Eq.…”

“…where α and k are material constants. Generally, these constants are expressed in terms of the cohesion (c) and the internal friction angle ( φ ) [13]. Therefore, the surfaces of both DP and MC yield criteria are made to coincide along the compression meridian, and then the constants α and k are related to the constants c and φ by [45] given in Eq.…”

“…A large literature has grown up which extends analytical and numerical models applied to masonry structures. These models involve mechanical parameters that are difficult to measure and cannot be implemented practically into numerical analyses [2][3][4][5][6][7][8][9][10][11][12][13]. Researchers related to detailed micro-, simplified micro-and macro-FE modeling of masonry walls subjected to compression and shear have initially taken similar steps in the modeling process for masonry prisms and columns under concentric loading.…”

This study primarily focuses on the constitutive modeling of masonry walls strengthened with fiber-reinforced polymers (FRP). In general, providing suitable relations for the material characterization of the masonry constituents so that the nonlinear finite element (NLFEA) applications of the elasto-plastic theory achieves a close fit to the experimental load-displacement diagrams of the walls subjected to in-plane loadings is desired. In this chapter, two relations proposed for masonry columns confined with FRP are adjusted for the cohesion and the internal friction angle of both units and mortar. Relating the mechanical parameters to the uniaxial compression strength and the hydrostatic pressure acting over the wall surface, the effects of major and intermediate principal stresses σ 1 and σ 2 on the yielding and the shape of the deviatoric section are then reflected into the analyses. Finally, NLFEA results for the walls tested in different studies showed a good match with the experimental ones.

Uncertainty results in misestimate of the shear resistance of unreinforced masonry walls. The misestimate is difficult to correct using deterministic calculation models even when sophisticated numerical models are used. To address this issue, the authors converted the deterministic calculation models for shear resistance of unreinforced masonry walls into prior Gaussian process models and then collected experimental results to train the prior Gaussian process models. They evaluated the resultant posterior Gaussian process models and found two of them are preferable. The two favorable posterior Gaussian process models can well interpolate the collected experimental results and can predict the shear resistance of the unreinforced masonry walls in the authors' experiments with full information. The interpolation and predication demonstrate that the posterior Gaussian process models can combine and weight prior engineering judgments and observational information from experimental results and then can quantitatively specify the remaining uncertainty of the estimation. In addition, the Gaussian process models are efficient, favorable for reliability analysis, and easily improvable. Therefore, they are potentially useful in engineering practices.
