Abstract: The measurement of internal strain with a fully noninvasive method should allow us to obtain very useful information, both in laboratory testing and in structural monitoring. Fiber optic sensors are suitable for this purpose ...

Abstract: This paper deals with nondestructive testing of high strength concrete. An experimental program was carried out, involving both destructive and nondestructive methods applied to different concrete mixtures, with cube ...

Abstract: A procedure for assessing stiffness variations due to damaging and retrofitting of reinforced concrete beams is presented in this paper. This procedure is based on modal analysis and testing. Two beams were subjected to ...

Abstract: This paper investigates strengthening masonry walls using glass-fiber reinforced polymer (GFRP) sheets. An experimental research program was undertaken. Both clay and concrete brick specimens were tested, with and without ...
