The test consists of loading the beam in two points until it reaches its ultimate deformation. The beam has a 30 x 15 cm section with 2ø14mm on the upper side and 2ø18mm on the lower side, the length equals 400cm. Smartec installed three distributed strain cables inside the beam (SmartProfileSMARTProfile II and Hydro&Geo) and the other two below the beam (SMARTProfile and SMARTape).
