This article presents the application of monitoring and detection of structural damage techniques to a historic monument. Seville cathedral’s famous bell tower ‘La Giralda’ is 96 m tall and is crowned with a large 16th century sculpture known as ‘Giraldillo’. The sculpture is supported with an internal bar structure, which is fitted over the axis about which it rotates according to the wind direction, allowing it to function as a weathervane. Between 1999 and 2005 the Giraldillo was demounted… 
Experimental image and range scanner datasets fusion in SHM for displacement detection
Optical images and signals can be used to detect displacement in civil engineering structures. This paper presents a technical experimentation of a vision‐based technology and artificial intelligence
A Theoretical Study on an Elastic Polymer Thin Film-Based Capacitive Wind-Pressure Sensor
By using the numerical calibration based on the presented closed-form solution the proposed sensor is designed into a nonlinear sensor with larger pressure-monitoring range and faster response speed than the linear sensor usually based on experimental calibration.
Structural Health Monitoring Systems for Smart Heritage and Infrastructures in Spain
The development of information and communication technologies (ICT) and robotics is currently demonstrating its potential impact on different fields of application. With regard to cultural heritage,
Wireless sensor networks for structure health monitoring: recent advances and future research directions
A contemporary look at the current state‐of‐the‐art in wireless sensor networks (WSNs) for structure health monitoring (SHM) applications and discuss the still‐open research issues in this field to make the decision‐making process more effective and direct.


One-year monitoring of the Z24-Bridge : environmental effects versus damage events
When using the analysis of vibration measurements as a tool for health monitoring of bridges, the problem arises of separating abnormal changes from normal changes in the dynamic behaviour. Normal

Damage identification and health monitoring of structural and mechanical systems from changes in their vibration characteristics: A literature review
This report contains a review of the technical literature concerning the detection, location, and characterization of structural damage via techniques that examine changes in measured structural
Illustration of the use of modal assurance criterion to detect structural changes in an Orbiter test specimen
The analysis of empirical modal models of structural components using techniques based on the modal assurance criterion (MAC) defined by Ewins (1984) is discussed and demonstrated for the case of the
Structural health monitoring of the Z24 Bridge in Switzerland was studied using the measurement data from three damage configurations. Changes in the modal parameters were used to detect possible
Damage detection from changes in curvature mode shapes
Structural Health Monitoring Using Statistical Process Control
This paper poses the process of structural health monitoring in the context of a statistical pattern recognition paradigm. This paper particularly focuses on applying a statistical process control
Abstract When performing vibration tests on civil engineering structures, it is often unpractical and expensive to use artificial excitation (shakers, drop weights). Ambient excitation on the
Modal Identification of Output-Only Systems using Frequency Domain Decomposition
By introducing a decomposition of the spectral density function matrix, the response spectra can be separated into a set of single degree of freedom systems, each corresponding to an individual mode, and close modes can be identified with high accuracy even in the case of strong noise contamination of the signals.
Engineering Applications of Correlation and Spectral Analysis
This chapter discusses single-Input/Single-Output Relationships, nonstationary data analysis techniques, and procedures to Solve Multiple- Input/Multiple-Output Problems.
