%X this work shows a non-invasive method for micro-deformation measurements of concrete structures using bragg grating sensors in optical fibers adhered to the surface. measurements on roadway slabs under a 10 kn static load are made, finding an approximated ratio of 2 : 1 between the deformation registered by the sensors and the values from a computational simulation with the finite element method. we propose the use of these sensors for slab structural monitoring in a road network employing distributed and wavelength multiplexed sensors. this is a first report in colombia of roadway slabs microdeformation measurement using fiber optic sensors.
