More than 6,000,000 tons/year can be shipped, of which about 60% are flat rolled, products, inland has a series of subsidiaries in warehousing, metal building, and containers which are also steel users. Total corporate sales are in excess of $2 billion...

As an economic and safe structure, Bi-steel is widely used in reinforced concrete with less consumption of steel. In this paper, III Bi-steel concrete beam has been analyzed. Through careful observation and theoretical analysis, the new calculating formulae for structural rigidity and crack have been formulated for this Bi-steel concrete beam. And structural rigidity and the crack features have...

Title of Document: NUMERICAL STUDY OF SEISMIC BEHAVIOR OF HIGH STRENGTH STEEL REPLACEABLE SHEAR LINKS Huiling Hu Master of Science, 2015 Directed By: Yunfeng Zhang, Professor Department of Civil and Environmental Engineering Eccentrically Braced Frames (EBFs) have been widely used in seismic protection and remediation in the recent years. However, the seismic behavior of shear links made of hig...

Introduction In the 1970s, exterior bonded steel reinforcement was used sporadically to reinforce bridges to attain higher service load capacities. This steel post-strengthening system consisted of steel straps bonded with epoxies to the exterior of concrete beams. An alternative to the steel retrofit is woven carbon fiber reinforced polymer fabric applied in the same manner as steel. Carbon fi...

The problem: A new type of steel is known as Twining Induced Plasticity Steel, more commonly known as TWIP Steel. There is a general interest in using this type of steel in the automotive industry due to its unique material properties such as super toughness and super ductility, although its chemical properties also play a vital role. It has a high content of Mn (more than 25%) and about 3% Si ...

The study on the dynamic characteristics of light steel residential structural system has both theoretical and practical significance for the application and promotion of light steel residential structural system. In this paper, we analyze several common types of light steel residential structural system, describe the dynamic characteristics of the light steel residential structural system for ...

The behaviors of bar-reinforced concrete filled steel tubular columns subjected to axial load were studied. One plain concrete filled steel tubular column and three bar-reinforced concrete filled steel tubular columns were tested. The deformation of specimens and the strain of steel tubes were measured. Based on experimental researches, a simple numerical analysis method was presented to simula...

The metallic low and intermediate level radioactive waste generally consists of carbon steel and stainless steels. The corrosion rate of carbon steel in deep groundwater is typically low, unless the water is very acidic or microbial activity in the environment is high. Therefore, the assessment of microbially induced corrosion of carbon steel in deep bedrock environment has become important for...

The demand for cleaner steels increases every year. In addition to lowering non-metallic oxide inclusions and controlling their size distribution, morphology, and composition, clean steel requires control of sulfur, phosphorus, hydrogen, nitrogen and even carbon, and minimizing metallic impurity elements such as As, Sn, Sb, Se, Cu, Zn, Pb, Cd, Te and Bi. These requirements vary with steel grade...

Abstract: Polyurethane-steel sandwich structure, which creatively uses the polyurethane-steel sandwich composite as a structural material, is proposed to strengthen the impact resistance of buildings under debris flow. The impact resistance of polyurethane-steel sandwich structure under debris flow is investigated by a series of impact loading tests, compared with that of traditional steel fram...
