    Estimation of Settlement-Induced Damage in Masonry Buildings From Displacement Measurements
    (Pergamon-elsevier Science Ltd, 2025) Liu, Yiyan; Burd, Harvey; Gulen, Derya Burcu; Dalgic, Korhan Deniz; Gilson, Ben; Ilki, Alper; Acikgoz, Sinan
    In current engineering practice, building damage due to nearby ground excavation activities is typically quantified by processing displacement measurements. Building displacements at discrete points are used to determine deflection measures (such as angular distortion) which are then employed to estimate building strains using elastic beam models; damage is subsequently categorised according to the limiting tensile strain criteria. The reliability of this procedure relies on the extent to which the equivalent beam models employed in the analysis provide a realistic representation of the building behaviour. However, few published investigations are available on this issue. The current paper provides an appraisal of displacement-based building damage estimation techniques by employing digital image correlation displacement data collected from a recent experimental campaign on the settlement response of three half-scale masonry buildings. The results demonstrate that the treatment of buildings with equivalent beam models does not capture building deformation kinematics, potentially leading to inaccurate estimations of damage severity and location. An alternative strain interpretation procedure, inspired by an equivalent frame idealisation of a building fa & ccedil;ade with openings, is proposed. This procedure, which uses a limited number of displacement measurements, offers a robust interpretation of strains. Its effectiveness in estimating damage is assessed through experimental data. It is demonstrated that the current limiting tensile strain criteria need to be modified to provide a reliable estimation of crack widths when using the equivalent frame idealisation.

    Large Scale Experimental Settlement Tests To Evaluate Structural Models for Tunnelling-Induced Damage Analysis
    (Springer, 2021) Dalgıç, Korhan Deniz; Gülen, D. Burcu; Açıkgöz, Sinan; Burd, Harvey; Hendriks, Max A.N.; Giardina, Giardina; İlki, Alper
    Underground construction activities, such as tunnelling, cause local ground movements to occur. Nearby surface structures interact with the moving ground, potentially leading to building damage. Although it is understood that the severity of building damage is influenced by the façade opening ratio (OpR) and the stiffness of the floors, experimental work in this area is lacking. This paper describes the specification and design of an experimental campaign on brick masonry buildings subjected to vertical base movements. The specimens are half-scale models of walls of two-storey buildings; models with different window arrangements and with/without floor slabs are examined. To design the experimental setup, 3D finite element analyses of the model walls were conducted. Key analysis results, presented in this paper, indicate how the examined structural properties (OpR, building weight, floor stiffness) are expected to influence the patterns of damage in the masonry. The finite element results are also used to design an instrumentation system comprising Fibre Bragg Grating (FBG) sensors and a digital image correlation (DIC) system. Data from the tests will support the formulation and validation of structural models for predicting tunnelling-induced damage in masonry buildings. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
