STRUCTURAL INTEGRITY OF BUILDINGS AND NATURAL HAZARD RISK
We determine the vibration behaviour of structures, e.g. through targeted excitation with the vibration exciter MoSeS. We then compare the results of these on-site measurements with the vibrations we calculated using simulation models of the structures. The resulting model serves as a basis for damage detection and evaluations of danger zones, rockfalls and earthquakes.
MONITORING AND CONDITION ASSESSMENT: BUILDINGS, BRIDGES AND INFRASTRUCTURE
We analyse the state of buildings and condition changes of essential infrastructure structures such as bridges via permanent structural health monitoring. Dedicated sensors and evaluation routines continuously record and transmit data as well as warnings for exceeded threshold values. If the cause of the damage is also to be recorded, we use numerical models to identify correlations between damage scenarios and measured value changes.
QUALITATIVE ANALYSES & REPORTS AND ACCURATE FORECASTS AT YOUR DISPOSAL
We provide you with detailed reports containing a range of results from our monitoring and analysis of structure conditions and safety assessments. We identify risks, make predictions and evaluate preventative measures. You can also use our prediction models and monitoring systems for your purposes.
THE SAFETY OF STRUCTURES IS A CRUCIAL FACTOR
Traffic, ageing, natural hazards or vibrations – any of these can cause considerable damage to buildings and infrastructure. Researchers at AIT are addressing this problem with the goal of ensuring a safe, resilient transport network and predicting the service life and risks of structures.
WE PROVIDE SUPPORT FOR YOUR MAINTENANCE PLANNING
What is the lifespan and serviceability of your buildings? How safe are they? When exactly do you need to take action in order to prevent damage, and what impact could natural hazards have? We provide you with clear and accurate answers to these questions. This gives infrastructure and building operators, the construction industry, state authorities, and engineers the leading edge they need for safety precautions and other future measures.
Permanently-installed sensors allow us to continuously record data and transmit it, automate data evaluation and measurement report creation, and send warnings in case of exceeded limits.
Numeric simulations in structural dynamics:
Using numerical modelling and calculations, we perform realistic simulations to determine the integrity or vibration behaviour of structures. These include, among others, dynamic time history analyses of rockfall events, earthquakes or simulations of subsurface waves in the soil.
