Bond behavior between glulam and GFRP’s by pullout tests [PDF]

Composites Part B: Engineering, 2012
Abstract To evaluate the bond behavior between glulam and GFRP rods, applied according to the near-surface mounted strengthening technique, an experimental program composed of beam and direct pullout tests was carried. In this experimental program three main variables were analyzed: the GFRP type, the GFRP location into the groove, and the bond ...

A Unified Model for Fibers With Divergent Pullout Behaviors in Strain Hardening Cementitious Composites (SHCC)

Frontiers in Materials, 2022
Strain Hardening Cementitious Composites (SHCC) are materials exhibiting high tensile ductility with the formation of multiple cracks. Since the mechanical properties of SHCC members are governed by the interfacial characteristics between fibers and ...

Biomechanical comparison of pedicle screw fixation strength in synthetic bones: Effects of screw shape, core/thread profile and cement augmentation.

PLoS ONE, 2020
Pedicle screw loosening resulting from insufficient bone-screw interfacial holding power is not uncommon. The screw shape and thread profile are considered important factors of the screw fixation strength. This work investigated the difference in pullout

Bearing characteristics of reinforced soil with longitudinal and transverse ribs of geogrids

Yantu gongcheng xuebao, 2018
In order to study the stress characteristics of interface between longitudinal and transverse ribs of geogrids and sand, the pullout tests are carried out under different normal pressures. Six pull-out test conditions are designed by trimming ribs in the

Pullout Characteristics of Waste Fishing Net Reinforced Bottom Ash using Pullout Test [PDF]

Journal of the Korean Geosynthetic Society, 2013
ABSTRACT In this study, pullout tests were carried out to evaluate pullout characteristics of waste fishing net (WFN), which added into bottom ash for recycling both bottom ash and WFN. Three different mesh size of WFN (WFN20:20 mm × 20 mm, WFN30:30 mm × 30 mm, WFN40:40 mm × 40 mm) and geogrid were added as a reinforcement.
