Regarding multiaxial loading tests, conventional measuring methods for the determination of strains are limited in showing the material behavior of specimens, especially in the range of small deformations. As a result, the measured strains are influenced within the entire loading range and a correction might be required. This paper presents a measuring method that uses fiber Bragg gratings to determine strains inside concrete specimens and provides test results as expected, even concerning small strains. By applying six measuring points in a tetrahedron-shaped arrangement, normal and shear strains can be determined. Reference measurements with strain gauges at uniaxial loading tests show that this measuring method produces reliable test results. Regarding multiaxial loading tests with compression-compression-tension loads, a realistic determination of the deformation behavior was also possible.
