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 ...

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 ...

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 ...

Experimental and numerical investigation of tensile behavior of non-laminated CFRP straps

Thomas Keller, Anastasios Vassilopoulos, Haifeng Fan

Tensile experiments were performed on seven-layer non-laminated carbon fiber-reinforced polymer (CFRP) straps. A corresponding finite element (FE) model was developed and validated by the experimental results. The anchoring of the outermost tape layer by f ...

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 ...
