How Is Temperature Affecting Your Strain Measurement what is q550nh weather steel for bridge - NI

Aug 25, 2020By using two or four strain gages in a Wheatstone bridge, you can minimize the effect of temperature. These are called half-bridge and full-bridge configurations, respectively. See Figures 4 and 5. With all strain gages in a bridge at the same temperature and mounted on the same material, any changes in temperature affect all gages in the same way.How does thermal expansion affect bridges? SocraticJul 16, 2014Thermal expansion can affect bridges with either expanding or contracting the bridge (or, by essentially distorting it's shape). If a bridge gets very heated, the road bed will expand. On the other hand, if the bridge is cooled, the road bed will retract.
