Bridge Health Monitoring System - IOSR Journals

During construction the bridge was tested which showed its wind resistance to be 78m/s When the wind speed exceeds this value a warning is given by the monitoring system. The Akashi Kaikyo Bridge can handle accelerations due to earthquakes of magnitude of 8.5 Richter scale.

Thermal bridge - Wikipedia

A thermal bridge, also called a cold bridge, heat bridge, or thermal bypass, is an area or component of an object which has higher thermal conductivity than the surrounding materials, creating a path of least resistance for heat transfer. Thermal bridges result in an overall reduction in thermal resistance of the object. The term is frequently discussed in the context of a building's thermal ...

Strain gauge - Wikipedia

A strain gauge (also spelled strain gage) is a device used to measure strain on an object. Invented by Edward E. Simmons and Arthur C. Ruge in 1938, the most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil pattern. The gauge is attached to the object by a suitable adhesive, such as cyanoacrylate.
