This study considered the possibility of using steel gabion baskets made welded mesh for a soil-strengthening function. Examples such applications are known meshes wires with diameters from 6.3 to 12.7 mm and openings 125 225 mm. In case grid, pulling resistance fine-grained soil consists two factors: frictional bearing resistance. Therefore, purposes this issue, simplified laboratory pullout t...

BACKGROUND There have been numerous studies conducted to investigate the pullout force of pedicle screws in bone with different material properties. However, fewer studies have investigated the region of effect (RoE), stress distribution and contour pattern of the cancellous bone surrounding the pedicle screw. METHODS Screw pullout experiments were performed from two different foams and the c...

The pullout methods LOK- TEST and CAPO-TEST for in-place compressive strength are presented with their theoretical analysis’ background correlations from 30 major studies, made worldwide, showing robust general between force by cylinders or cubes/ cores. coefficient of variation the systems shown, reported in 1984. Practical cases using described: Case 1. In-Situ testing quarantined precast con...

INTRODUCTION Early-stage pullout is a common problem for surgeons during the fixation of osteoporotic bones. Poor bone quality limits the use of pedicle screws for patients with osteoporosis. In this study, the researchers investigated the effects of hole and gap position and type on the pullout strength of cannulated screws. METHODS Seven different designs were tested, including a control gr...

A large scale experimental program using vertical and batter model piles in sand subjected to pull out loads has been carried out in a model tank of size 1m x 1m x 1m. Mild steel pipes of varying diameters, lengths, and shapes are used as model piles. A poorly graded river sand having specific gravity G= 2.67, Uniformity coefficient= 3.53, emax = 0.81, emin = 0.54 has been used as foundation me...
