Abstract

Several procedures for design of UHPC use formulations based on a strain compatibility analysis, which can be extended to a serviceability-based design by incorporation of full material stress-strain relationship. The material models can be implemented in finite element and elastic-plasticsolution methodologies in order to close the gap among properties, analysis, modeling, and design. The tensile characteristics of UHPC can be defined in the context of fiber content and response after the matrix has fully cracked. The general terms of strain softening and/or strain hardening are defined, and additional sub-classes of deflection-softening and -hardening may be outlined based on the behavior in bending.

Keywords: UHPC, Serviceability, Fiber reinforced UHPC, Hybrid reinforced UHPC
