Load transfer mechanisms in CFRP ground anchors with multi-strap ends

Thomas Keller, Anastasios Vassilopoulos, Haifeng Fan

An investigation of the load-transfer mechanism in carbon fiber-reinforced polymer (CFRP) ground anchors with multi-strap ends was conducted based on experimental and numerical studies of one- and two-strap anchors. Differences in the strap geometry, i.e. ...

Pull-Out Behavior of CFRP Single-Strap Ground Anchors

Thomas Keller, Anastasios Vassilopoulos, Haifeng Fan

Pull-out experiments were performed on four carbon fiber-reinforced polymer (CFRP) ground anchors simulating their applications in rock and soil. The CFRP tendons used in these anchors comprise a single-strap end on both ground and air sides. On the ground ...

Pull-out behavior of CFRP ground anchors with two-strap ends

Thomas Keller, Anastasios Vassilopoulos, Haifeng Fan

Pull-out experiments were performed on three carbon fiber-reinforced polymer (CFRP) ground anchors simulating their applications in different rock types which provided different confinement levels. The CFRP tendons comprised, on the ground side, a prefabri ...

Evaluation of grout materials for CFRP ground anchors with strap ends

Thomas Keller, Anastasios Vassilopoulos, Haifeng Fan

An evaluation of cement- and resin-based grout materials for applications in carbon fiber-reinforced polymer (CFRP) ground anchor heads composed of high-strength grout and a CFRP strap was conducted. Uniaxial compression experiments were performed on cylin ...

Structural performance of permanent post-tensioned CFRP ground anchors with strap ends

Haifeng Fan

Permanent post-tensioned ground anchors are widely used for the stabilization of different structures in civil engineering. Carbon fiber-reinforced polymer (CFRP) tendons have been proposed to replace steel tendons in ground anchors to solve the durability ...

Fatigue behavior of hybrid GFRP-concrete bridge decks under sagging moment

Haifeng Fan, Yuqing Liu

This paper presents a new cost-effective hybrid GFRP-Concrete deck system that the GFRP panel serves as both tensile reinforcement and stay-in-place form. In order to understand the fatigue behavior of such hybrid deck, fatigue test on a full-scale specime ...
