Team:	Bridge and Foundation Engineering Team
Roadmap/Focus area(s):	Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:	Recent advances in concrete materials have led to a new generation of cementitious materials, namely ultra-high performance concrete. This concrete possesses advanced properties in terms of compressive behavior, durability, and tensile load carrying capacity. Ultra-high performance concrete attains these behaviors via an optimized gradation of cementitious materials, chemical admixtures, and steel fiber reinforcement. The current project aims to investigate the tensile fatigue behavior of this type of concrete through the flexural testing of 18 medium scale prestressed rectangular beams. In this test program, the cyclic load levels will focus on the cracking strength of the ultra-high performance concrete to allow for the determination of the steel fiber reinforcement behaviors under fatigue loading.
