Manuel Bermudez, Chung-Chan Hung

Abstract:

This paper re-evaluates existing definitions of tensile strain hardening in ultra-high-performance concrete (UHPC) materials and provides practical guidance for interpreting and reporting tensile stress–strain data, including identification of key parameters relevant to structural applications. This paper provides engineers with an overview of existing methods and recommends an approach that enables objective, consistent interpretation and reporting of the UHPC tensile stress–strain curve to qualify tensile strain-hardening properties for structural applications.

Abstract:

Glass fiber-reinforced polymer (GFRP) reinforcement is currently only allowed to be used in concrete structures in Seismic Design Category (SDC) A. An approach explored in this article is the use of GFRP reinforcement for structural elements that are not intended to be part of the inelastic (yielding) mechanism of the seismic force-resisting systems.
