This paper studies the no-bracket construction technology for reinforced concrete reinforcement, and uses planting-bar as support to solve problem that scaffolding cannot be erected due site factors. Firstly, steel bar pullout test was carried out study influence of strength, planting diameter, depth, structure type on force planting-bar. Secondly, finite element method used simulate selection ...

The aim of this study was to analyze clinical and radiologic results of an arthroscopic medial plication with the pullout technique and to define indications and limitations of this procedure for patellar instability. Records of 45 patients treated for patellar instability with arthroscopic medial plication with the pullout technique were reviewed. The mean patient age was 22.8±8.3 years. The t...

BACKGROUND Monsegmental pedicle instrumentation (MSPI) has been used to treat thoracolumbar fractures. However, there are few reports about the biomechanical characteristics of MSPI compared with traditional short-segment pedicle instrumentation (SSPI) in management of unstable thoracolumbar fractures, and the influence of vertebral fracture on screw stability is still unclear. METHODS This s...

Title of Document: HUMERAL FRACTURE FIXATION TECHNIQUES: A FEA COMPARISON OF LOCKING AND COMPRESSION TECHNIQUES WITH CADAVERIC PULLOUT COMPARISON OF CORTICAL COMPRESSION AND INTERNAL LOCKING SCREWS. Aaron Johnson, MS Mechanical Engineering, 2007 Directed By: Professor, Donald Barker, Mechanical Engineering Locking and non-locking humeral repair techniques provide different mechanical constructs...

Inertial e4ects in the mechanism of 'bre pullout (or push-in) are examined, with emphasis on how the rate of propagation of stress waves along the 'bre, and thence the pullout dynamics, are governed by friction and the propagation of companion waves excited in the matrix. With a simple shear lag model (assuming zero debond energy at the 'bre/matrix interface), the e4ect of uniform frictional co...

Increasing demand for large-sized Floating, Storage and Regasification Units (FSRUs) for oil and gas industries led to the development of novel geometric form of Buoyant Leg Storage and Regasification Platform (BLSRP). BLSRP consists of a circular deck supported by six buoyant legs placed symmetrically with respect to wave direction. Circular deck is connected to buoyant legs using hinged joint...

Abstract Anchor heads could efficiently address the bond weakness between Fibre-Reinforced Polymer bars and concrete. This experimental study enhanced behaviour GFRP concrete using three innovative anchorage systems made from glass fibre cloth epoxy resin. A direct pullout test was used to bond-slip performance bar Test variables were diameter (3 diameters), compressive strength (20.4 40.2 MPa)...

BACKGROUND The biomechanical performance of the hooks and screws in spinal posterior instrumentation is not well-characterized. Screw-bone interface failure at the uppermost and lowermost vertebrae is not uncommon. Some have advocated for the use of supplement hooks to prevent screw loosening. However, studies describing methods for combined hook and screw systems that fully address the benefit...
