Push Out

Relying on a practical application in pre-stressed concrete box-girder with corrugated steel web, four models of Twin-PBL shear connector are made and experimented in push-out test. The main research contents are influences for bearing capacity and load-slip relationship. The results show that: when the size of holes on the steel plate has a definite value, the connectors bearing capacity get a significantly development when the diameter of reinforced-throughout increases in the appropriate range. If the space between reinforced-throughout and holes are too small, the coarse aggregate will be prevented into the holes so as to reduce its bearing capacity. In addition, thickness of steel plate has less influence on bearing capacity of connectors. All models show similar load-slip trend and superior ductility. Finally, according to comparing and analyzing differences between calculated values from recommended formulas and measured values from tests, a new formula is deduced which can estimate the test results well. The standardization of push-out test needs further research so that Twin-PBL Shear Connectors can be widely used in project.

Polymerization Method

Electro polymerization of N-benzothiazolyl maleamic acid (NBM) was carried out on stainless steel plate electrode in a protic medium of monomer aqueous solution using electrochemical oxidation procedure in electrochemical cell.Spectroscopic characterization techniques were investigated to obtain information about the chemical structure of polymer. The anti-corrosion action of polymer was investigated on stainless steel by electrochemical polarization method. In addition, the effect of adding nanomaterial (TiO2, ZnO (bulk-nano)) to monomer solution on the corrosion behavior of stainless steel was investigated. The results obtained showed that the corrosion rate of S-steel increased with temperature increase from 293K to 323K and the values of inhibition efficiency by coating polymer increase with nanomaterial addition. Apparent energies of activation have been calculated for the corrosion process of S-steel in acidic medium before and after polymeric coating. Furthermore were studied the effect of the preparing polymer on some strain of bacteria.
