In the event of a disaster, expert knowledge is essential in order to make a rapid assessment of the situation. Once the cause is known, the appropriate measures can be taken. Information from a disaster can also be used to prevent similar incidents and is useful input for formulating standards, regulations and guidelines for consultancy firms in the field of design and construction.
The consequences of damage due to a structural fault or structural ageing are often serious. Apart from economic damage, there may also be human victims. TNO provides information by carrying out an independent technical investigation into the causes of the structural damage.
The causes of damage to a structure can be established in various ways:
- by inspecting the site
- by conducting interviews
- by assessing the design calculations and other documents
- by making additional calculations
- by assessing possible scenarios against current regulations
Background information on regulations is essential in order to determine whether calculations are applicable and accurate. TNO has this knowledge because it contributes to the formulation of national and international regulations, and is therefore a reliable partner in the provision of specialist knowledge in technical investigations.
Examples of projects
TNO has been involved in many damage investigations in recent years, including ASR damage in bridges and viaducts, the locks at Eefde and Kampen, the B Tower in Rotterdam. We also use our expertise to analyse damage in other types of buildings.
