Experimental structural evaluation and rehabilitation
Natural Hazards and Risks in Structural Engineering (NHRE) M.Sc.
Students will be familiar with instrumental methods and instrumentation requirements to provide structure related parameters and characteristic force-displacement relationships in support of analytical studies and the outcome of field surveys. Students should be able to decide upon appropriate test configuration for particular problems related to failure cases or on-going projects, and to use the infrastructure for further graduation (master thesis).
P1 - Experimental Structural evaluation (2 SPW – L; 3CP)
Testing facilities and technical equipment; demands on specimens and scaling requirements; arrangement of sensors, application of equivalent forces and ground motion in pseudostatic and dynamic testing; Load and displacement relationship for full-scale testing of structural elements (RC columns, masonry wall); damping devices, prediction of capacity curves and material properties and parameters; recalculation of model calibration
P2 - Model testing for rehabilitation (2 SPW – P; 2CP)
Experimental investigation of design and retrofitting strategies using small scale structural models; testing of elements and interpretation of failure mechanism, derivation of structural layout and simplified models of representative building types, damage prognosis and comparison with observed response; fragility functions
Introduction in data processing for simulation tools 3Muri
P3 - Signal processing and interpretation (1 SPW – L; 1 CP)
Conditioning of experimental data, error analysis, analog and digital filters; Fast Wavelet-Transform, compression and denoising algorithms; tool: MATLAB
