Vibration Measurements on a Cable-Stayed Cyclist Arch Bridge for Assessment of the Dynamic Behaviouratural frequencies of the deck, 12 accelerometers were placed at different locations on the deck, after which the deck was excited using a 250 kg impact hammer at five locations. The first natural frequency of the cables varied between 2.11 Hz for the longest cable and 8.51 Hz for the shortest cable

Experimental and Numerical Characterization of the Dynamic Behaviour of a Historic Suspension Footbr under dead load was experimentally measured during the field survey. The results of field vibration tests were used to calibrate and validate the numerical model of the footbridge, e.g., boundary conditions, and initial cable tension. The present study reports the results of the geometrical survey,

Vision-Based Vibration Measurement of Stay-Cables by Video Motion Magnification and Dynamic Mode Decement information. A single video data can be used to obtain displacement at any desired location of the target structure which in the other methods would either require to mount at multiple locations or conducting repetitive tests. In this paper the cable vibration is captured by video camera and t

A Fiber-Optic Ultrasonic Visualization Technique for Damage Detection in a 1000 °C Environment a high-temperature in-situ damage diagnosis using a laser ultrasonic visualization system combined with a remote FBG-based sensing configuration. In this method, an ultrasonic wave is excited by the laser irradiation on the surface of a material and then received by the remotely installed FBG senso

Experimental Investigation of Galloping Susceptibility of U Beams with Different Flange Porositye indicating the proneness to transversal galloping was determined for U-beams with porosity up to fifty percent. The prism with flange porosity of seventy five percent revealed as a practically stable due to low positive value of slope within only narrow angular interval around zero angle of wind a

Development of Sensor Unit for Extraction/Transmission of Only Peak Acceleration Response. The developed sensor unit would provide the useful information for estimating the damage situation in the area in which the building is located. The proposed sensor unit has been tested utilizing the opportunity of full-scale steel hospital building shake table experiments at the E-Defense.

Getting StartED with Mac OS X Leopard the damage indicators. This paper demonstrates the evaluation of local property changes in two examples of large-scale structures: a 14-story RC building and a 64 m long pedestrian bridge. The proposed damage indicators show a clear correspondence to structural changes.
