    Engineering Structures
    In this paper, a material model for masonry under a plane stress state and subjected to quasi-static monotonous loading is presented along with the implementation of the model in the nonlinear finite element method. Using macro modelling, a masonry element consisting of bricks and joints is assumed. Taking into account the compatibility and equilibrium conditions, constitutive laws are formulated, which describe the nonlinear and anisotropic properties of masonry based on consistent mechanical correlations. By introducing an additional local model, influences due to discontinuities can be taken into account in a continuum-mechanics approach. The developed constitutive laws are presented, the numerical implementation within the NLFE method is illustrated, and NLFE analyses of the load–deformation behaviour of experimentally investigated shear walls with various material combinations and kinematic, static, and geometric boundary conditions are carried out.

    Computational Modelling of Concrete and Concrete Structures
    The critical parts of structures are typically discontinuity regions, where abrupt changes in geometry occur or large concentrated loads are applied. In engineering practice the verification of the ultimate limit stage of such discontinuity regions employs strut-and-tie models or stress fields based on the lower bound theorem of plasticity theory. These models are mechanically consistent but they can be prohibitively time consuming and are not directly applicable for serviceability limit state analysis as they do not consider strain compatibility. To overcome these limitations the Compatible Stress Field Method (CSFM) was developed for the design and assessment of discontinuity regions in concrete structures. The CSFM consists of a simplified nonlinear finite element-based stress field analysis procedure.Considering compatibility and equilibrium conditions at stressfree cracks, uniaxial constitutive laws as provided in concrete standards are used. While the concrete tensile strength neglected in terms of strength, the CSFM accounts for tension stiffening to obtain realistic predictions of deflections and crack widths, and cover the deformation capacity aspects. The effective compressive strength of concrete is automatically evaluated based on the transverse strain state. The present work validates the ability of the CSFM to reproduce the observed behaviour of experimentally tested frame corners with an opening moment. A quantitative comparison between the outcomes from the numerical analyses and reported experimental results proves the CSFM to be a reliable tool for assessing the structural behaviour of discontinuity regions. In addition, a numerical study is conducted to investigate the sensitivity of the CSFM to several input and model parameters.
