In order to quantitatively evaluate the shear-bearing capacity of shear connectors of square concrete filled steel tube (CFST), push-out tests on 14 square CFSTs with shear connectors have been carried out. Among the 14 CFSTs, there are 13 specimens with steel plate connectors and one specimen with steel bar connectors. The following factors are investigated to figure out their influences on th...

In this paper, a new type of steel-concrete composite member, concrete-filled core steel tube with outer angle steel plank reinforced concrete stub column, is proposed and a series of nonlinear 3D(three-dimensional) full-range numerical calculations under axial compression are carried out, some important factors are analyzed, such as the strength of the concrete, the steel tube and the angle st...

The human mirror system has been the subject of much research over the past two decades, but little is known about the timecourse of mirror responses. In addition, it is unclear whether mirror and counter-mirror effects follow the same timecourse. We used single-pulse transcranial magnetic stimulation to investigate the timecourse of mirror and counter-mirror responses in the human brain. Exper...

The optical constants of a linear chain carbon (LCC) film in the spectral range from 248 to 1100 nm (1.13-5.0 eV with step 0.1 eV) were obtained by Beatty ellipsometric method, and its thickness was determined. LCC deposited on pre-polished mirror surface massive steel sample using technology pulsed plasma ion stimulation. It found that measured spectrum refractive index varies 2.35 2.73, value...

Steel has remained the most crucial of all structural materials. However, the steel production processes have changed over the years. Currently, due to the tendency of eliminating high energy consuming technologies, in both the international and domestic steel industry, liquid steel is manufactured in two basic aggregates: oxygen-blown converters and electric arc furnaces 1 . The development of...

Shot-peening treatment was applied to a quenched and tempered DIN 34CrNiMo6 steel improve its high-cycle R: −1 axial fatigue strength. Compared with the machined condition, increase in limit 21.8%. S-N curves for shot-peened as condition were presented compared those obtained previous research rotating bending fatigue, including mirror-polished specimens. The shot-peening this work (Isp: 8A 200...
