Streszczenie:

Spike anchors are one of the most promising techniques to prevent or delay debonding in FRP reinforcement sheets. There are several parameters affecting the anchors’ capacity, such as the embedment length and dowel angle. Regardless of the anchors’ capacity, their contribution to the overall strength of the anchored joint is affected by a larger number of variables, including the bonded length behind the anchors, the number and arrangement of the anchors, and the contact surface between the anchor fan and the FRP sheet. This paper presents experimental results of 10 tests conducted on concrete

Ground anchor corrosion is a common problem for anchored slopes in Taiwan. It is partly due to the humid climate condition and abundant groundwater in the slope and partly due to poor corrosion protection of anchor design and construction. In 2010, an anchored slope at Taiwan National Freeway No. 3 failed suddenly after 13 years of service. It buried 3 cars and killed 4 people. It caught the public’s attention and initiated the island-wide program on over hauling the anchors slopes in Taiwan.

This paper evaluates the performance of expansion anchors used to attach helical pile connectors to foundations. The anchors’ response to pullout loads was evaluated using nonlinear finite element analysis with the aid of the commercial software, Abaqus. The connector capacity under horizontal movement of the foundation for different anchor diameters, embedment depths, and anchors’ spacing is reported. It was found that the pre-tension load had no influence on the anchor ultimate capacity, but affected the anchor response at service load levels and the displacement at failure. Under pullout lo

This paper reports an investigation on the influence of anchors made from fibre-reinforced polymer (herein FRP anchors) when applied to FRP-to-concrete bonds. The experimental section of the paper consists of 44 tests on FRP-to-concrete joints of which 20 joints are unanchored controls and 24 joints are anchored with FRP anchors. The influence of plate width, plate thickness and plate elastic modulus are considered as these parameters have received little to no attention to date. An increase in plate width is shown to considerably enhance the joint strength although the influence of the anchor

The axial performance of CFRP is excellent, while the lateral compression strength and shear strength are low, thus they can’t be anchored by traditional anchors. A new type of adhesive anchor was designed and five experimental cables were fabricated and the static tests were carried out. In the tests, the tensile capacity, bond strength and pullout behavior of CFRP cables anchors filled with resin were discussed. The efficiency coefficients and the load-slip behaviors of the bond-type anchors and the uniformities of the stresses in the tendons were studied. Several conclusions are drawn which

The novelty of the present study is to address the durability of corroded anchors for prestressing CFRP laminates. Two types of steel anchors, clamp anchors and wedge anchors, were used to prestress CFRP laminates and then subjected to steel corrosion through a galvanostatic acceleration approach, which was followed by tensile tests. Compared to clamp anchors, wedge anchors showed a superior durability performance in terms of their prestress retention, anchor efficiency, and resistance to the slippage of the CFRP laminate.

Abstract Torpedo anchors are dynamically installed anchors for the mooring systems of floating platforms and received the name of "torpedo" due to the cone head and the fin tail. Commonly used torpedo anchors have a diameter of around 1.0m (typically between 0.7 to 1.3m) and a length-to-diameter ratio of less than 20. During an offshore installation, the anchor will be lowered down to a height from the seabed about 50-100m. Once released from the releasing mechanism, the anchor will fall through the water column and penetrate into soil reaching the target depth within 10s. The target embedment

These anchors are known to be cost-effective and capable of withstanding high vertical loads. Despite their successful usage in the offshore industry, the increasing loads imposed by the mooring systems in ultra-deepwater applications demand higher anchor holding capacities. In this scenario, a possible solution is to consider a group of torpedo anchors, which has not been investigated.

Dynamically embedded plate anchors are rocket shaped anchors that penetrate to a target depth in the seabed by the kinetic energy obtained through free-fall. After embedment the central shaft is retrieved leaving the anchor flukes vertically embedded in the seabed. The flukes constitute the load bearing element as a plate anchor. This paper provides an overview of an experimental and numerical study undertaken to provide the first performance data for this anchor concept. The experimental work includes geotechnical centrifuge modelling and field tests using three different reduced anchor scale

Two series of experiments were conducted to evaluate the uplift capacity of Bridge Supplemental Set (BSS) anchors in weak/dense soils. Six anchors were installed in two different sites consisting of very soft soils, and tension was applied until uplift. Experimental uplift capacities were compared to theoretical minimum capacities, which proved to be a conservative way to estimate anchor capacity. Minimum average installation torque of 1,750 ft-lb was recommended. Sixteen anchors were installed in six different sites with dense soils. Soils with N values of 22 and higher prohibited anchor inst

This report describes a research project for evaluating the applicability of the widely accepted 80 percent criterion for elongation of ground anchors to anchors with unbonded lengths exceeding 100 feet. This issue is driven by several recent projects involving ground anchors for landslide stabilization in which a significant percentage of the anchors did not meet the criterion that requires measured elongation during proof load testing of at least 80 percent of the theoretical elastic elongation. The projects involved anchor unbonded lengths in the range of 85 to 220 feet, which is outside th

Ground anchors connected to guy wires for tower structures in cold climates suffer from frost heaving, which causes loss of wire tension and subsequent structural instability. It is necessary to understand what ground anchors are available to resist this tendency yet are still capable of expedient installation in remote areas. To that end, three metal, traditional ground-anchor types (arrowhead, bullet, and penetrating auger) and one novel polyvinyl chloride (PVC) T-post anchor were evaluated in frozen gravels and frozen silts at a research facility in Fairbanks, Alaska. Criteria included inst

Streszczenie:

Proof-of-concept testing was conducted to determine the viability of helical anchor installation using the US Army’s High Mobility Engineer Excavator (HMEE). To facilitate the proof-of-concept test, a new hydraulic hose kit was designed that connects the Bridge Supplemental Set (BSS) drive motor to the HMEE’s auxiliary hydraulic system. Additionally, a steel mount was fabricated that provided means to attach the BSS drive motor to the boom of the HMEE. Testing indicated the HMEE can successfully install the BSS anchors with the required hardware, but the vehicle’s large footprint will likely i
