Ultra-High-Performance Concrete Crack Propagation Based on Fiber Random Distribution Model
Frontiers in Materials, 2022 The tensile strength, crack behavior, and strain-hardening properties of ultra-high-performance concrete (UHPC) are mainly affected by the steel fibers distributed in the matrix. In this study, a mesoscopic model of UHPC was established using a numerical

Experimental investigation on UHPC shrinkage of full-scale steel-UHPC composite bridge deck
Developments in the Built Environment, 2023 Three full-scale composite bridge deck segments with various steel-to-UHPC area ratios, as well as free shrinkage specimens, were tested to investigate the restrained shrinkage and cracking behaviors. Based on the measured UHPC strain and temperature, the variations in shrinkage strain were analyzed, and a time-varying analysis theory for calculating ...

Utilizing Full UHPC Compressive Strength in Steel Reinforced UHPC Beams
Second International Interactive Symposium on UHPC, 2019 Steel reinforced ultra-high performance concrete (R/UHPC) flexural members commonly fail by fracture of the steel reinforcement after crack localization rather than crushing of the cement-based matrix as expected in traditional reinforced concrete. When failing after crack localization, R/UHPC specimens show low drift capacity and the high composite ...
