Bridge Testing – Technique making these massive structures standing

I read many articles on bridge manufacturing techniques where I come to know about various methods mechanical engineers undertake to made these big structures. Not only their manufacturing but ensuring that a bridge will withstand all conditions is also a major thing that cannot be compromised at all. This is why scientists employ many tools and techniques to ensure these structure stand for years without any major outbreak.

While browsing through various articles, somewhere I read about bridge testing. It's a technique that engineers use to test a bridge on various fronts. Right from its design to its load handling capability is determined using this technique. This technique involves the use of various tools and sensors that help engineers determine the most accurate readings about bridge characteristics. There are many companies out in the market that manufacture, supply and install geotechnical and structural sensors for monitoring strain tilt, displacement, slope monitoring and pressure.The scope of bridge testing comes under the area of structural monitoring. Some of the services under this area include diagnostic load testing, structural monitoring, balancing forces for lift bridges, concrete reinforcement location services, weighing permit loads, on-line data monitoring service, cable force testing, girder transportation force monitoring, concrete curing temperature monitoring, residual stress testing, and roadway vertical clearance measurement.For load testing services, engineers use specialized field equipments and analytical software which delivers most effective results eventually. Field tests are conducted with a readily available vehicle and the data used to correct a finite element model of the structure. Based on the field-calibrated model, accurate load ratings are determined  including effectiveness of strengthening and other repairs, overload and permit loads, and accurate load ratings HS-20 and any other design vehicles.Structural monitoring helps the user to determine various things about the bridge such as Monitor crack growth in concrete members, pier rotations due to scour (marine structures), expansion joint displacements due to temperature fluctuations, fatigue cycle counting, and overloaded vehicle weight enforcement. The parameters measured during the balancing operation are Shear strains on drive shafts using wireless transmitter, displacements at bridge corners, cable forces either with load cells or accelerometers, and motor current draw. Engineers use a precised set of portable scales and we can meet the load as they enter your jurisdiction and quickly and efficiently weigh them.Want to know more about bridge testing?
