Design and application of structural health monitoring system in long-span cable-membrane structure

An enhanced indirect video-based measurement procedure for dynamic structural system identification applications

“…The FFT-based frequency spectra of the output motion signals are presented in Figs. 19 and 20 for 1-1 and 1-2 cases. For minaret 2, the results are similar and are not shown here due to brevity.…”

“…Vibration-based dynamic system identification process has been performed in historical buildings and sufficient results and experiences have been obtained [8][9][10][11][12]. This process was also examined for bridges [13][14][15][16][17][18][19], buildings [11,[20][21][22][23][24][25] and tall towers [26][27][28][29][30][31][32]. This method is more effective for bridge structures, due to their considerable permanent ambient vibrations [18,19].…”

This method is more effective for bridge structures, due to their considerable permanent ambient vibrations [18,19]. Also, the historical tall towers such as minarets and bell towers are appropriate cases for investigation using this method because they have a high level of structural height and consequently strong vibrations during daily ambient excitations.…”

Integrating Ionic Electroactive Polymer Actuators and Sensors Into Adaptive Building Skins – Potentials and Limitations

“…Strong wind loads, for example, first need to be detected before potential countermeasures can be taken. It is often desired to have locally resolved data about induced mechanical stresses inside membrane structures for health monitoring purposes and to ensure the serviceability and safety of the structure (Tang et al, 2019). We propose soft and flexible IEAP sensors for direct integration into tensile membrane structures as a viable alternative to the installation of conventional acceleration sensors and displacement meters.…”

Design and Testing of a Structural Monitoring System in an Almería-Type Tensioned Structure Greenhouse

“…Wind direction was measured with a vane (accuracy ± 5 • ). In structures with a high sensitivity to wind, it is necessary to know both its direction and speed [42]. The suction load due to wind in windward and leeward roofs is greater when the wind is oblique, producing an increase in the axial force on the columns, which is more considerable if case of supporting columns [43].…”
