TENSION STIFFENING AND DAMAGE TOLERANCE OF STRAIN-HARDENING CEMENT COMPOSITE (SHCC) TENSION TIES UNDER MONOTONIC AND REPEATED CYCLIC LOADINGS
This paper describes the influence of cement-based composites ductility and damage-tolerant capacity on the tension stiffening performance and cracking process of reinforced cement-based composite tension ties. The effect of loading scheme (monotonic and repeated loading) was also investigated. Testing was carried out on six axially loaded tension tie specimens. Each specimen had a square cross-section dimension of 110 x 110mm and length of 500mm. Improved tension stiffening performance in strain-hardening cement-based composites (SHCCs), characterized by the tensile strain-hardening response with multiple cracking, contributes to reduced crack widths, i.e., multiple cracking. Limited amounts of repeated loading with SHCC specimens did not appear to affect the member response nor lead to an increase in crack widths.
