Axial Reinforcement

It is clear from the former researches on reinforced concrete filled tubular steel (RCFT) structures that RCFT structures have better performance than concrete filled tubular steel (CFT) structures, in other words, because of the existence of reinforcement, the performance of RCFT differed from that of CFT. Therefore, to clarify the effect of axial reinforcement on mechanical properties of RCFT, compression tests of RCFT columns with different ratio of axial reinforcement were carried out, meanwhile, corresponding tests of CFT, reinforced concrete (RC), pure concrete, and steel tube columns were done to compare with RCFT. By a series of comparison and analysis, effect of axial reinforcement on RCFT columns were discussed, and following conclusions were drawn: reinforcement ratio has direct effect on performance of RCFT. Over arranged reinforcement will cause pre-failure of concrete without exerting strength of reinforcement, and not only may cause brittle-failure or lower performance of the structure, but also cause the increase of construction cost. On the contrary, proper ratio of reinforcement can make the RCFT possess better confined effect, improve overall performance of the RCFT structure; furthermore, whatever the ratio of reinforcement, RCFT has better performance than both CFT and RC, especially possesses more brittle-failure resistance than CFT.

Abstract Alloy Steel 3.5Ni-1.8Cr-0.4Mo-0.1V is highly suitable for massive components, usually more than four inches thick. It has high hardenability which in a water-spray or water-immersion quench contributes to the formation of sizeable amounts of martensite along with some bainite, and possibly a little ferrite. On tempering, the martensite adds to toughness and lowers the temperature of transition from tough to brittle failure. This steel is suitable for intermediate-duty and heavy-duty generator and turbine rotors, large axles and shafts, large gears and ship forgings. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, and machining. Filing Code: SA-404. Producer or source: Alloy steel mills and foundries.

Comprehensive Study

The problem of corrosion for old steel bridges in operation is often solved by direct replacement of elements or structure. Only a few studies have been done to determine the efforts influenced by corrosion in those elements. In general, it is considered that a corroded element has exceeded the bearing capacity and should be replaced, but if the corroded element is secondary it could be treated and kept. A factor in the rehabilitation of an old steel bridge in operation is the aspect of structure. If the structure is corroded, rehabilitation decision is taken is easier. Lamellar tearing describes the cracking that occurs beneath the weld and can be characterized as a brittle failure of steel, in the direction perpendicular to the plane of rolling. The paper presents a comprehensive study on lamellar tearing and summarizes some conclusions about the prevention of them. The conclusions will be exemplified in the case of a railway bridge, with a main truss girder. The paper presents also some observations regarding the stress analysis in fillet welds, resulting from the engineering practice.
