Strainstall in Structural Monitoring – measuring, analysing and reporting
The structural monitoring services provided by Strainstall include the short and long term monitoring of complete structures such as buildings, bridges and plant, as well as structural monitoring of components of large marine vessels, road and rail vehicles. These range from static data logger systems to high speed/high data rate dynamic monitoring systems with intelligent data processing and reduction instrumentation. A wide range of sensors are used to measure parameters such as strain, stress, load, acceleration, displacement, vibration, temperature and pressure. Strainstall’s experience provides the right sensors together with the right monitoring instrumentation, to give the client the right service and answers.
  
Structural Health Monitoring
Many new civil structures are fitted with structural health monitoring systems to measure a range of parameters and record the data to check that the structure behaves as intended, and to confirm or extend design life. As with any long-term structural health monitoring system, usually the data produced confirms that everything is behaving correctly. For this reason, Strainstall’s system incorporates sophisticated software that processes data as it is collected, and consequently, summarised data is always available. Large volumes of data are only stored under pre-set alarm conditions. The same benefits can be extended to existing structures where information is required to either solve a problem or again, to extend its life by verifying that it is still structurally safe and fit for purpose.

In-Situ Stress Determination
In-Situ stress measurement is based upon instrumented stress relief techniques. These include instrumented coring for concrete, instrumented drilling for steel beams, reinforcement bars and post tensioning tendons, and pressure compensation slot cutting for concrete and masonry |

Dynamic Testing
The dynamic testing capabilities of Strainstall are extensive, and include high speed, multi-channel data collection. Tasks encompass fatigue life analysis and estimation of prototype vehicles, dynamic load response testing of bridges, high-speed stress and vibration testing of aero engines. Our dynamic testing experience is backed up by many years of working around the world in the construction, railway, offshore, marine, aerospace and manufacturing industries, providing us with very different and varying challenges to produce the right data and the right answers.

Monitoring Systems
Strainstall design, assemble, programme, install and operate monitoring systems of varying complexity. These range from simple battery powered static logging systems to fully automated structural health monitoring systems. Strainstall’s sound understanding of industry requirements ensures that all systems provide the most appropriate and meaningful information to ensure any significant change in the condition or behaviour of a structure will be logged and reported. An internet based monitoring system has also been introduced. |

StrainSoft Analysis
StrainSoft is a software package that takes data from data acquisition systems and analyses and presents the results in a graphical, easy to interpret format. It has been designed specifically for structural testing by Strainstall experts, who have utilised their many years of experience in monitoring and testing to create this user friendly program. StrainSoft accepts data from Strainstall data acquisition systems, but can also be configured to take information from any other systems with data as set up files that are available in ASCII format. |
