摘要

Ultra-high performance concrete (UHPC) is an advanced cementitious composite material which has been developed in recent decades. When compared to more conventional cement-based concrete materials, UHPC tends to exhibit superior properties such as increased durability, strength, and long-term stability. This computational investigation focused on modeling the behaviors of existing UHPC structural components including a prestressed UHPC AASHTO Type II girder and a prestressed UHPC 2nd generation pi-girder. Both a concrete smeared cracking model and a concrete damaged plasticity model were tailored to model UHPC within a commercially available finite element analysis package. The concrete damaged plasticity model using three types of tension stiffening definitions can replicate both linear and nonlinear structural responses of both girders reasonably well. A set of UHPC constitutive properties were developed that facilitate the model replication of the local and global responses observed in the series of physical tests. The finite element analysis modeling techniques developed herein are intended to be applicable to other UHPC structural components.
