Data recording

Data recording in civil engineering often requires that the system is left in place for several days or weeks, colleting data and sending it to the base station. The systems monitors structures, noise, vibration, movement, temperatures and other parameters. There are many systems on the market which can do it, the main strength of DEWESoft is the ability to record high speed and low speed data at the same time, video signal and data from other sources.

Application The application is to measure strain and discplacement on the areas fixed with steel nets. The system must be installed on site for several weeks, gathering data. Measurement challenge The system should recorder data from strain gages, load cells, displacement, temperature and others. The main requirement is that it is easy to handle , so everyone can use it. The Dewesoft NET adds the ability to remotely control the system and observe current data. Steel net research Steel net research Steel net research Steel net research

Dynamic signal analysis

The dynamic signal analysis is widely used in an area of civil engineering. Remember Tacoma bridge? The structures are being checked for natural frequencies, against wind and water waves excitation. The structures and parts of structures are submitted to static and dynamic stress tests.

Bridge monitoring

Monitoring of bridges are becoming more and more important issue since the bridge constructions are getting longer and more complicated. Lots of bridges are monitoring lately with permanent systems.

DEWESoft ability to store lots of channels and acquire data simultaneously from different systems along the bridge makes it perfectly suitable for these kind of applications. Usually the data is acquired from strain, displacement and GPS sensors.

Bridge monitoring with DEWESoft.

Bridge monitoring	Wind and structural health monitoring for Stonecutters bridge WASHMS, China	View
Application This is typical application of bridge measurement. The sensor and system are permanently installed on the bridge constantly monitoring the dynamic and static behavior of the bridge. The data is transfered to the control center for analysis. Measurement challenge The system consists of several measurement units, measuring strain, displacement, forces, accelerometers, wind speed and direction, rain, temperature, humidity, air pressure, GPS and others, resulting in more than thousand measurement points. Dewesoft works on all the measurement instruments, but acts like a single instruments providing live and history data for all measurement parameters.

Bridge monitoring	Bridge monitoring Stralsund, Germany	View
Application After the completion of more than 350 m long bridge, the demand is to measure dynamic behavior and wind profile of the bridge. The system is installed in the bridge itself collecting data during deployment. Measurement challenge The system is measuring vibrations, displacements, temperatures and wind profile. It records the initial behavior of the bridge and will monitor any change in behavior which could result in failure. The report from ADAC concludes that 10% of all bridges in Germany are in very bad condition and only 30% are in good condition, therefore there is a high need for monitoring or at least occasional inspection. This bridge is a good example what is the correct way of doing measurement already at the start of operation.
