Comparison of different finite element model updates based on experimental onsite testing: the case study of San Giovanni in Macerata
Journal of Civil Structural Health Monitoring - Tập 11 - Trang 767-790 - 2021
Understanding the behavior of historic structures that have undergone structural changes, restorations, and damage over time is still a significant challenge for structural engineers, particularly in those countries subject to high seismic risk, such as Italy. The study of built heritage for its prevention and conservation is an active research topic, due to the numerous uncertainties present in h...... hiện toàn bộ
Model calibration in the presence of resonant non-structural elements
Journal of Civil Structural Health Monitoring - Tập 5 - Trang 37-55 - 2014
Accurate finite element models are needed in many applications of Civil Engineering. Non-structural elements (NSEs) often interfere with the main structure, altering its stiffness and modal signature. Neglecting such interaction, although a common practice in design, may lead to unreliable predictions of the structural dynamic response and to biased interpretations of experimental vibrational test...... hiện toàn bộ

Wall length-based deformation monitoring method of brick-concrete buildings in mining area using terrestrial laser scanning
Journal of Civil Structural Health Monitoring - Tập 13 - Trang 1077-1090 - 2023
For brick-concrete buildings which are easily damaged by mining activities, this study conducted measurements using a terrestrial laser scanning and adopted the wall length as a deformation monitoring index. First, the point cloud data of the individual walls are extracted by segmenting the building-point cloud data and redistributing the wall-point cloud data. Second, after individual walls were ...... hiện toàn bộ
P3P: a software suite for autonomous SHM of bridge networks
Journal of Civil Structural Health Monitoring - Tập 13 - Trang 1577-1594 - 2022
This paper presents the development of a new software code for the fully autonomous management of permanent integrated Structural Health Monitoring (SHM) systems installed in highway bridge structures. The code was developed within the framework of a research project funded by Anas S.p.A., the largest public infrastructure manager in Italy. The software program includes all the necessary steps to ...... hiện toàn bộ
Giám sát độ tin cậy kết cấu của cầu dầm gỗ ở khu vực miền nông thôn Australia Dịch bởi AI
Journal of Civil Structural Health Monitoring - Tập 6 - Trang 751-761 - 2016
Có hàng ngàn cầu dầm gỗ phân bố khắp khu vực miền nông thôn Australia, chủ yếu được giám sát thông qua việc kiểm tra trực quan. Kinh nghiệm từ những thất bại trong quá khứ đã dẫn đến sự nhận thức rõ ràng rằng kiểm tra trực quan với khoảng thời gian nhiều tháng hoặc năm là không đủ để phát hiện những hỏng hóc tiềm ẩn do quá tải và sự suy thoái sinh học. Một cây cầu bị quá tải hôm nay có thể bị hỏng...... hiện toàn bộ

Multi-bandwidth wavelet transform of impact echo signals for delamination detection of thin concrete slabs
Journal of Civil Structural Health Monitoring - Tập 6 - Trang 649-664 - 2016
In this study, a multi-bandwidth wavelet transform of signals with mixed frequencies from multiple delamination mechanisms is proposed to achieve the time and frequency resolution required in delamination detection. It was applied to detect six embedded defects, simulating shallow and deep delamination, in a 60 in. × 36 in. × 7.25 in. reinforced concrete slab from impact echo signals recorded at 4...... hiện toàn bộ
Damage identification under ambient vibration and unpredictable signal nature
Journal of Civil Structural Health Monitoring - Tập 11 - Trang 1253-1273 - 2021
Ambient vibration is an unknown excitation source that may produce stationary or non-stationary signals. Under such circumstances, traditional feature extraction techniques may not yield relevant features to damage and not provide reliable results of damage identification. The main objective of this article is to propose a data-driven method based on the concept of statistical pattern recognition ...... hiện toàn bộ
A novel methodology based on the reflected L(0,1) guided wave for quantitative detection of corrosion-induced wall thickness loss in continuous pipes
Journal of Civil Structural Health Monitoring - Tập 14 - Trang 67-82 - 2023
Corrosion-induced wall thickness loss (CIWTL) can reduce the strength and integrity of a pipe, threatening its normal operation. Effective detection of CIWTL in pipes helps ensure their safe operation. This paper presents a novel methodology based on the reflected L(0,1) guided wave to quantitatively detect CIWTL in a continuous pipe. Investigating the effects of CIWTL and propagation length on ti...... hiện toàn bộ
