Shi, Z. (author), Su, Q. (author), Kavoura, Dr. Florentia (author), Veljkovic, M. (author)To establish the tensile constitutive model of ultra-high performance concrete containing coarse aggregate (CA-UHPC), monotonic and cyclic uniaxial tensile tests for CA-UHPC with fiber volume fractions of 2.5% and 2.0% were conducted. Test results showed that CA-UHPC exhibits approximately linear stress-strain relation up to the tensile strength...journal article 2023

Shi, Z. (author), Su, Qingtian (author), Kavoura, Dr. Florentia (author), Veljkovic, M. (author)To investigate the fatigue performance and fatigue damage process of the Orthotropic Steel Deck (OSD) - Ultra-High Performance Concrete (UHPC) composite bridge deck, a two-span continuous full-scale specimen was designed and tested under cyclic loading. Test results showed that the fatigue cracks firstly initiated near the lower part of the weld...journal article 2023

Shi, Z. (author), Su, Qingtian (author), Kavoura, Dr. Florentia (author), Veljkovic, M. (author)The short-headed stud connectors play a critical role on the interaction of the orthotropic steel deck (OSD) and the ultra-high performance concrete (UHPC) layer in orthotropic steel-UHPC composite bridge deck. In this paper, the fatigue behavior of these short-headed stud connectors was experimentally investigated in a beam test. The failure...journal article 2022
