Local steel millers may raise billet pricesOoi Tee Ching
Roadside barriers have been developed over the years to safely redirect vehicles that leave the roadway. Many different rigid, semi-rigid and flexible designs for roadside barriers have been evolved. The most common system consist of a steel w-beam rail supported on ...
[钢结构][笔记] 钢梁的局部稳定与腹板加劲肋 (Local Stability of Steel Beam and Web Stiffeners) 实干、实践、积累、思考、创新。 (1)对于轧制型钢梁,由于翼缘及腹板的厚度相对较大,一般没有局部稳定问题。焊接板梁则通常需要验算板件的局部稳定。 (2)工字钢翼缘的局部稳定通常通过宽厚比来保证,宽厚比的限值...
aLoad redistribution due to yielding of highly stressed local areas of a steel or RC-continuous beam is a well known example for a passive system. Metallic or friction dampers are using the concept of energy dissipation to reduce the vibration of structures. Various other applications are one-way...

Dr. Han Seong-Tae's team at KERI's Industry Applications Research Division has developed the core technology of "electron guns," the heart of "electron beam welders," which had been dependent on imports for more than 99%.
In concrete-filled steel tubular (CFST) beam-columns under cyclic loadings, local buckling of restrained steel tube, crushing and slipping of the confined concrete could have significant influences on strength and stiffness degradation. This paper presents a numerical model based on fiber element ...
