At present, the scattered and closed steel logistics resource should be integrated. Reasonable benefit allocation mechanism is the prerequisite for steel logistics resources integration. Based on previous studies on steel logistics resource integration, this paper proposes an important problem in steel logistics resources integration: benefit distribution. First, this paper gives the classifica...

The corrosion of steel reinforcement in an aging highway infrastructure is a major problem currently facing the transportation engineering community, in particular bridge engineers. In the United States, maintenance and replacement costs are measured in billions of dollars. Further, the use of deicing salts has resulted in steady deterioration of bridge decks due to corrosion. These concerns ha...

This investigation compared four conventional vehicle armour materials for performance under blast loading. The parameters measured were resistance to deformation, mechanical toughness and metallurgical microstructure. It was found that two of these, the M steel and A steel, showed the least deformation and M steel showed better shock energy absorption. B steel had high toughness but showed sig...

The structural behavior fire-resistant steel is essential; fire-resistant steel is proven to have higher strength at elevated temperature than that of conventional steel. Also, the requirement of fire protection in the fire-resisting steel can be relaxed as compared with conventional steel structures. However, the design criteria for the application of the fire-resisting steel in steel columns ...

The microstructure of steel is decisive for its chemical, physical and mechanical properties. Depending on the parameters characterising liquid metal as well as the parameters of the steel casting influencing the crystallisation process, the macrostructure of casts and ingots consist of three, two or only one crystallisation zone. In steel ingots, its most frequent by consist of three zones: ch...

In this paper, we developed the direct repair welding method without eliminating load when of great steel truss is going. According to information about process and data systematized, working for eliminate defect joint analyzing used FEM on stability result welding-repair were scientific more than last time at structure. When do did not from part so it’s necessity use any Jackie turning back. T...

OBJECTIVE To evaluate the quantitative effects on torque expression of varying the slot size of stainless steel orthodontic brackets and the dimension of stainless steel wire, and to analyze the limitations of the experimental methods used. MATERIALS AND METHODS In vitro studies measuring torque expression in conventional and self-ligating stainless steel brackets with a torque-measuring devi...

Health Act) in three cases, and inpatient treatment as a condition of a probation order in two cases. A "medical" disposal (including community care in one case) occurred in all the schizophrenic and subnormal patients. In contrast, three of the four patients in the manipulative group were given a prison sentence. It is apparent from the criminal statistics that men commit child stealing offenc...
