A structural experimental technique to characterize the viscoelastic behavior of concrete under restrained deformations

This work was funded by FEDER through the Program COMPETE and by the Portuguese foundation FCT— Fundacao para a Ciencia e a Tecnologia, which provided support to the Research Units CONSTRUCT and ISISE, to the research projects PTDC/ECM/099250/2008, PTDC/ECM/ 122446/2010 and PTDC/ECM‐EST/1056/2014, and to the PhD grant SFRH/BD/76183/2011 of the second author. The kind assistance of Jose Granja from University of Minho in conducting the elasticity modulus monitoring through ambient response method test is gratefully acknowledged.
