Abstract: This paper presents the results of pullout bond tests on fiber-reinforced polymer (FRP) tendons embedded in cement mortar filled steel tubes. The pullout test program involved four types of FRP bars, three types of grouts, ...

Abstract: This paper presents laboratory experimental results on new Fabry-Perot fiber-optic sensors to verify their behavior and applicability for strain monitoring of engineering materials and structures. The research program ...

Abstract: Past test data show that the bond stress distribution of bond anchorages is nonuniform along the bonded length and that the point of the peak bond strength shifts from the entry of the tendon to an inside point of the ...

Abstract: This paper presents laboratory tests on a bond-type anchorage system and a full-scale ground anchor with fiber-reinforced polymer 9-bar tendons. A cement-based mortar filled steel tube was used to simulate a rock mass ...

Abstract: The research work reported in this paper involves investigation of the tensile behavior of fiber-reinforced polymer (FRP) ground anchors. Variables of the tests on the anchor models were anchor fixed length, tendon type, ...
