Not as much in Sweden as in other countries, but even in our country there are many examples where measurements on structures have provided very valuable information to assess safety and function. <\/p>\n\n<h2 class=\"gb-headline gb-headline-7d0c2c50 gb-headline-text\">In this area we offer:<\/h2>\n\n<ul class=\"wp-block-list\">\n<li>Inspections<\/li>\n\n\n\n<li>Supervision<\/li>\n\n\n\n<li>Instrumentation and measurement<\/li>\n\n\n\n<li>Evaluation of measurement data<\/li>\n\n\n\n<li>Functional checks<\/li>\n\n\n\n<li>Verifications by testing<\/li>\n<\/ul>\n\n<p>We do this through complete measurement systems, wireless or wired, installed on site, local data collection or with remote monitoring.

Although we mainly measure on concrete structures, the same technique can of course be used on steel and wooden structures. <\/p>\n\n<h2 class=\"gb-headline gb-headline-1be51a05 gb-headline-text\">Most common is registration of:<\/h2>\n\n<ul class=\"wp-block-list\">\n<li>Deformations and displacements<\/li>\n\n\n\n<li>Straightening<\/li>\n\n\n\n<li>Movements (accelerations)<\/li>\n\n\n\n<li>temperature<\/li>\n\n\n\n<li>Load<\/li>\n<\/ul>\n\n<p>For example, it is possible to measure how much cracks move with load and temperature, how much a bridge bends under load, the natural frequency of a structure, etc.<\/p>\n\n<h2 class=\"gb-headline gb-headline-dcbafa2d gb-headline-text\">Evaluation of measurement data<\/h2>\n\n<p>Before installing measurement systems, the site has normally been analyzed. This is to know where to place sensors and further which measurement data to use in the analysis. The analysis can in some cases be performed with analytical methods, otherwise FE analysis. Sometimes trigger values are linked to the measurement, i.e. a level that requires extra attention or, in the worst case, a stop of traffic or production.    <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Condition assessment by measurement SHM (Structural Health Monitoring) sometimes CSHM (Civil Structural Health Monitoring) is an effective tool to improve the understanding of existing structures and thus the decision-making basis in connection with inspections and the development of action proposals.
