Special Issue Information

Dear Colleagues,

The structural health monitoring of buildings constitutes an area of research dedicated to ensuring the safety, durability and efficiency of constructed environment. Computational and experimental techniques are used to assess the integrity of buildings along time and to detect potential damage based on numerical and experimental methods.

In this Special Issue, papers dedicated to experimental and/or numerical studies on structural health monitoring are welcome. Applications of these practices in buildings, bridges and other structures are also welcome. This Special Issue will accept original research, case studies and state-of-the-art review papers.

Papers published in this Special Issue should describe original methods and studies in different topics of both science and engineering, such as mechanics of structures, dynamics of structures and nonlinear analysis. This Special Issue will be of interest to researchers and academics working in fields of service states, the structural analysis of buildings, infrastructure management and historical construction assessment.

Potential topics include but are not limited to the following:

  • Vibration analysis;
  • Damage identification;
  • Experimental modal analysis;
  • Rheological models;
  • Time-marching procedures;
  • Creep and relaxation;
  • Structural Engineering applications;
  • Robusteness of structures;
  • Experimental methods;
  • Structural faults;
  • Strengthening of strutures.

High-speed videogrammetric measurements are widely used on shaking tables. However, during progressive collapse experiments, the protective string used to ensure the safety of personnel and the shaking table, mandated by safety considerations, can partially occlude the structural model. To address the problem of inaccurate tracking of the ellipse targets in image sequences due to the partial occlusion, this paper proposes a novel mutually guided tracking method for the partial occlusion situations. Firstly, the strategy of loopback detection is proposed to eliminate the cumulative errors with the initial tracking model and to replace the initial results of the tracking with those from the loopback detection. Secondly, tiny offset compensation is used to solve the problem of deviations. The experimental results demonstrate that the proposed method can achieve single-point localization at the sub-millimeter level and interlayer localization at the millimeter level within partially occluded environments. It is important that the proposed method meets the requirements of experimental accuracy on shaking tables and ensures the safety of personnel and facilities. Full article

The main purpose of this article is to discuss the use of the Lyapunov exponents to evaluate the integrity of structures. The use of such coefficients is examined in an analysis that considers the geometric and physical nonlinearities, aiming to ensure the applicability of the method in robust simulations. The material nonlinearity is modeled using the multilinear isotropic elastoplastic model together with a recently developed damage model. The nonlinear equilibrium equations solution is obtained using the positional finite element method. The Newmark time-marching procedure is implemented to evaluate the Lyapunov coefficients and a nonlinear predictor technique that needs a single data series is employed. A numerical example of a frame structure is presented to illustrate the methodology applicability. Its results show that the Lyapunov exponents can be used as indicative parameters of structural integrity, since its analysis was able to detect the occurrence of the destabilization of the structure with the dynamic jump and the presence of material failures. The non-linear predictor proved to be an efficient technique for obtaining the Lyapunov exponents, with a low computational cost. The methodology presented to monitor structural integrity was shown to be a promising alternative. Full article
