Cyclic behaviour of textile-reinforced cementitious matrix composites (TRC) using distributed fibre optic sensors technology

This paper presents an experimental study on the local and global mechanical behaviours of textile-reinforced cementitious matrix composites (TRCs) subjected to cyclic loading. Two configurations are tested: TRCs with one two layers. These were tested under three different loading modes: monotonic until failure, in pre-cracking stage, crack propagation stage 3000 cycles. The was followed by a residual tensile test failure. equipped distributed fibre optic sensors placed at core specimens. enable internal behaviour textile/matrix interface help deduce evolution micro-mechanical parameters TRC, such as load transfer, shear stress contact mode interface. Moreover, digital image correlation technique is used assess widths for TRCs.
