Pressure-grouted helical pile (PGHP) is an innovative piling system that allows a significant increase in capacity with relatively low additional cost. The constructed by applying pressurized grout during the installation of conventional piles. injected into ground through two nozzles welded to hollow shaft. This paper presents comprehensive laboratory study investigate effect three different n...

This paper presents the design optimization of axial flux surface mounted Permanent Magnet Brushless DC motor based on genetic algorithm for an electrical vehicle application. The rating of the motor calculated form vehicle dynamics is 250 W, 150 rpm. The axial flux surface mounted Permanent Magnet Brushless DC (PMBLDC) motor was designed to fit in the rim of the wheel. There are several design...

While continuous powder mixing has been an area of active research in recent years, effects of operating conditions on the mixing performance has not been well understood yet. Based on our previously developed periodic section modeling (Gao et al., 2012), this paper examines the effects of operating conditions on two significant parameters of the continuous blending processes: axial velocity an...

Abstract The addition of nano-silica to ultra-high-performance concrete (UHPC) increase its toughness has been proposed obtain nano-concrete (UHPNC). This work mainly studies the reinforcement effect UHPNC on filled steel tube (CFST) columns under long-term load. Ten CFST strengthened with were selected and reinforced UHPNC. influences different thicknesses layer contents axial compression prop...
