Summary

Modern inverse analysis techniques have become essential in diverse engineering fields for parameter identification and system diagnosis. These methods utilize computational algorithms to deduce unknown structural or material parameters from observed data, aiding in the diagnosis and predictions of system anomalies while enhancing the accuracy of numerical models. The primary goal of inverse analysis is to bridge the gap between theoretical models and real-world structural behaviour, both at the material level and at scales of structural components. This facilitates more efficient maintenance, repair, and optimisation of structures. Recent advancements in numerical methods and optimisation algorithms have significantly improved the accuracy and applicability of inverse analysis, enabling more accurate identification of material properties, boundary conditions, and structural parameters. Within the framework of inverse analysis, there are numerous potential applications for parameter identification and structural diagnosis, both at the material level and across the entire structure.

This Special Issue of Structural Durability & Health Monitoring is devoted to methodology developments and application of some of the above outlined approaches, in diverse research fields such as (but not limited to) civil and mechanical engineering.

    Generalized Shear Correction Factor for Non-Homogeneous Beam Cross-Sections with an Embedded Steel Core

    Abstract In this study, an energy-consistent analytical–numerical framework is proposed to determine the effective shear correction factor ks for non-homogeneous cross-sections within the Timoshenko beam theory, such as a porous cementitious matrix (e.g., perlite-based material) combined with an embedded steel I-section. The formulation enforces equivalence between the real heterogeneous shear strain energy, governed by a spatial shear modulus field G(y,z), and its beam-theory representation based on ks(GrefA). A pixel/voxel discretization is introduced to evaluate the generalized shear-energy integral and to quantify the deviation of ks from classical homogeneous benchmarks. The results demonstrate… More >

    Static Analysis and Safety Assessment of Tilted Circular Sinking Wells

    Anna Szymczak-Graczyk, Tomasz Garbowski, Florim Grajçevci, Hajdar Sadiku
    Structural Durability & Health Monitoring, DOI:10.32604/sdhm.2026.079217
    (This article belongs to the Special Issue: Modern Inverse Analysis Approaches for Structural Diagnosis and Parameter Identifications)
    Abstract Sinking wells (open caissons) are widely used deep foundation structures whose installation by the cut-and-sink method may lead to unintended deviation from verticality due to heterogeneous soil conditions and construction irregularities. While tilting is a frequently observed phenomenon, quantitative criteria for assessing the admissibility of an inclined well after completion of sinking remain insufficiently defined. This study presents a static analytical framework for evaluating stress redistribution beneath the concrete plug of a tilted well. The analysis is based on eccentric vertical load transfer and derives closed-form relationships linking the permissible inclination angle to well geometry… More >
