Bond Behavior of Fiber Reinforced Polymer Bars Under Hinged Beam Conditions
… weight concrete (NWC) hinged beam-end specimens, tested in accordance with two laboratory conditions. Reinforcing bars of different diameter, material configuration, and finished surface preparation were tested for bond strength parameters determined in accordance with ACI Committee Report 440.3. …

Experimental and numerical investigations to assess the behaviour of a buried pipeline in areas with high geological instability
… have been designed to perform two groups of tests: simple interaction tests (axial pullout and transversal pullout test) and complex interaction tests (reproducing a pipeline crossing landslide). A system of steel containers (stationary and fixed) in which pipe samples are buried within the …

Frontal Plane Humeral Elevation Effects on the Pullout Strength of Suture Anchors Used in Rotator Cuff Repair
… eyelet breakage, suture failure, and anchor pullout. These failure modes necessitate intervention to reattach the tendon thus prolonging the healing period. Identifying and minimizing these failure modes will ensure optimum healing. There are two goals of this study. Firstly, the paper will …

Transfer and Development Lengths of Steel Strands in Full-Scale Prestressed Self-Consolidating Concrete Bridge Girders
… bridge girders. In the first phase, 56 pullout tests were conducted to compare the performance of seven-wire strands embedded in SCC and conventionally-consolidated concrete blocks. In the second phase, transfer lengths of prestressing strands in two SCC hollow box girders and two SCC …

Bond and Material Properties of Grade 270 and Grade 300 Prestressing Strands
… prestressing strand of various sizes. Tension tests were performed on each type of strand. The data from these tests was used to determine modulus of elasticity, yield stress, ultimate stress, and ultimate elongation for each strand. The yield stresses and ultimate stresses for many of the …

Engineering properties of ring shaped polytheylene terephthalate (RPET) fiber self-compacting concrete
… a weak interfacial bond with cement paste in the pullout load because of the lamellar shape of fibers. Therefore, ringshaped PET (RPET) fibers are introduced in this study to overcome the limitations of traditional straight, lamellar, or irregularly shaped fibers. RPET fibers are mainly designed …

Modeling of Strain-Hardening Cement-based Composites (SHCC)
… in the simulation was derived from single fiber pullout test and calibrated with several analyses. In the next step, 2D SHCC dumbbell specimens under tensile loading condition were simulated, and a series of numerical case studies were performed to assess the quality, credibility, and limitations …

Pullout Strength of Epoxy Anchors Installed Underwater
<p> This work presents the development of a test program and the results from the final round of testing to better understand the effect a submerged anchor installation has on the pullout strength of epoxy anchors. Two different epoxies were tested at embedment depths of two, four, and six bar …

Resistência ao arrancamento de grampos em solo residual de gnaisse
A adoção da técnica de solo grampeado no projeto de contenção de taludes ou escavações vem sendo cada vez mais freqüente, com isto se faz necessário um maior numero de estudos sobre a estimativa da resistência ao arrancamento (qs) em função de parâmetros de ensaios de campo para os mais variados …
