Author(s): H MAMAND , J CHEN
Abstract: This paper presented an extended digital image correlation technique (EDIC) for mapping damages in concretes. A digital image camera was used to scan the surfaces of investigated concrete beams during the loading process. The developed EDIC technique was used to computationally detect macro and micro cracks, and predict micro crack propagation before the crack become visually detectable. This developed EDIC technique is essential to carry out an in-situ mapping damages in concrete structures. This new technique firstly extended the capability of current digital image correlation technique by computational detecting multiscale cracks, which enables a non-destructive test of structural damages. This developed EDIC technique can be used for further research on material damages in the society of concrete academia and applications in detecting damages of ageing concrete structures in concrete related industries.

Abstract: This paper describes the mechanical properties of truss girders with Z-shaped clips through experiment. The result shows that the failure mode of truss girder is categorized as lateral buckling-induced destabilization. By comparing the mechanical performance and the economy indices between truss girder with butterfly-shaped clips and truss girder with Z-shaped clips, the feasibility of truss girder with Z-shaped clips is demonstrated.
