Prerequisits
In order to successfully participate in the learning process student need skills in the areas of: Structural mechanics (statics, dynamics, stability), Physics (basic knowledge of chapters on electricity, magnetism, optics), Engineering Surveying. Attendance at lectures and tutorials is mandatory since the student's individual work is very limited because of the specific nature of the course (interactive work and the use of measuring devices).  
Content (Syllabus outline)
Contents of lectures: ? general concepts concerning investigations of structures (the purpose of the investigation, specimens, loadings, surveying and physical measurements and observations) ? geodetic methods of displacement measurements (instruments, methods and compensations of the measured values, presentation of results, calculating the most probable value) ? electronic measurement of mechanical and other quantities (basis, accuracy and measurement uncertainty, configurations of the measuring equipment and software for data acquisition, measurement of strains, displacements, accelerations, inclinations, forces, torsion moments, hydraulic pressure, rotational speed, non-contact transmission of the measuring signals on rotating parts of structures, temperature, automation of measurements) ? use of calibration methods for indirectly measuring the displacements, forces and moments through the strain measurements ? processing, analysis and display of measurement results (filtering of measurement signals, analysis of disturbances and their causes, identification of the characteristics of the observed structures on the basis of measured quantities - determination of stiffness, eigen frequencies, damping, assessing the remaining lifetime of the structure based on the results of measurements ...) ? implementation of measurements on structures (the purpose of measurement, the problem of reference points for measuring displacements, determination of the number, position and the accessibility of measurement points, triggering and control of measurements, standards and regulations), examples of good practice ? monitoring of structures in various stages of construction and diagnostic methods for faults and defects of structures on the basis of measurement results. Contents of exercises: ? familiarization with measurement equipment, demonstration and implementation of individual measurements of displacements, strains, temperature, torque, forces, speed of rotation on simple structures in the lab) ? static and dynamic bending test of a beam (surveying and electronic measurements of displacements, strains, load size, processing of measurement signals, evaluation and presentation of measurement signals and comparison with the calculated response) ? demonstration and individual preparation of the measuring point for strain measurement on aluminum or steel cantilever bending element, implementation of the indirect force measurement with so prepared element after previous calibration ? The load test on real simpler bridging structure is implemented, where measurements of strains, vertical displacements and accelerations are performed; measured results are evaluated and graphically presented. A comparative static and dynamic analysis of the observed object is performed by the FE method using a suitable software tool, the computational and measurement results are compared and the causes of differences between the two are analyzed.

Objectives and competences
? learning about the crucial methods for measuring of mechanical and physical quantities caused by static and dynamic loadings of structures, ? learning about basic identification methods of structures and about the necessary instruments, ? the introduction to a systematic approach to investigations of constructions  
Intended learning outcomes - knowledge and understanding
Student will manage the methods of measuring of the structure response to static and dynamic loadings. He (she) will be able to process, evaluate and visualize the measuring results. 
Intended learning outcomes - transferable/key skills and other attributes
Students will be able to obtain the information of structure behavior experimentally and on the basis of these results either to confirm the relevance of the calculation model or identify the basic characteristics of existing structure and thereby assess its current status. 
Learning and teaching methods
? lectures with practical demonstrations of measurement techniques in the classroom and laboratory, and on the field ? exercises in laboratory and on the field
