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...

Corrosion causes reduction in cross-sectional area of reinforcement, deterioration mechanical properties, and degradation bonding properties between reinforced concrete, which are the most important factors leading to structural service performance. In order investigate progressive collapse mechanism a corroded concrete frame structure, failure modes, characteristics vertical displacement, load...

OBJECTIVE To determine the effect on ultimate push-out load and cement-stem surface shear strength of thermally manipulating the cobalt-chromium-molybdenum (CoCrMo) alloy stems of bone cement-stem constructs. METHODS Satin-finished CoCrMo alloy stems were allocated to the following three groups with the predetermined temperatures: T24, ambient (24 °C); T37, body (37 °C); and T44, pre-heated s...

We determine the ultimate classical information capacity of a linear time-invariant bosonic channel with additive phase-insensitive Gaussian noise. This channel can model fiber-optic communication at power levels below the threshold for significant nonlinear effects. We provide a general continuous-time result that gives the ultimate capacity for such a channel operating in the quasimonochromat...

Sequential small impact loads may not collapse structures directly but could weaken the strength of structures. This study aimed to investigate these sequential on reinforced concrete beams. First, six were applied test specimens. Then, residual static capacity impacted specimens was determined by ultimate load test, compared with those undamaged The experiment composed 12 having identical dime...
