In many studies, the alternative load path method (APM) has been used for progressive collapse analysis. In this method, one or several columns of the building are removed and the building response is investigated. This method ignores the initial local failure cause of building and this can affect the structural response. Investigation of ignoring the initial local failure cause of steel braced...

steel production in iran has been recorded since fourteen century b.c. however the main growth and development in steel industry has occurred in recent decades. steel industry has important role in development of industrial countries, and also steel consumption may consider as an important ind ices in the development process. this pap er has analyzed two main complexes (zobe ahan and mobarakch)...

Many phenomena in continuous casting including the formation of surface defects are greatly affected by heat transfer in the mold. The interfacial slag layers between the solidifying steel shell and the mold wall dominates the resistance to heat removal and thus controls mold heat transfer. Surface defects, such as longitudinal cracks and star cracks have been associated with variation of slag ...

On the boundary of any two phases a transition region is formed, designated as interphase, the composition of which is not identical with composition of the internal part of any of two phases. This transition region – interphase – is formed by effect of surface forces, given by the character and composition of both contacting phases, and its thickness is usually of the order of molecular dimens...

Monte Carlo (MC) simulations for recrystallization were performed using OIM (Orientation Image Microscopy) data sets to define the initial microstructures. Two types of OIM data sets were used as input to the simulations. One type was measured on a warm-rolled interstitial-free (IF) steel sheet. The results were strongly affected by the assumptions used to estimate the stored energy, which is t...

This paper investigates the powerplay in one-day cricket. The rules concerning the powerplay have been tinkered with over the years, and therefore the primary motivation of the paper is the assessment of the impact of the powerplay with respect to scoring. The form of the analysis takes a “what if” approach where powerplay outcomes are substituted with what might have happened had there been no...

Addition of steel fibers to high strength concrete (HSC) improves its post-peak behavior and energy absorbing capability, which can be described well in term of toughness. This paper attempts to obtain both analytically and experimentally the efficiency of steel fibers in HSC columns with hybrid confinement of transverse reinforcement and steel fibers. Toughness ratio (TR) to quantify the confi...

Climate change is one of the greatest challenges worldwide. Its most severe impacts may still be avoided if efforts are made to transform current energy systems. The notion of climate change mitigation refers to the reduction of the rate of climate change via management of its causal factors such as the emission of greenhouse gases from fossil fuel combustion, agriculture, land use changes, cem...

M. Mihaliková, M. Német, Faculty of Metallurgy, Technical University of Košice, Slovakia The present paper deals with measurements of the increments of strain and hardness HV10 on automotive steel sheets. The car body manufacture trends are focused, in particular, on high energy absorption capability. In the manufacture of a car body, there are requirements for high plasticity and homogeneity o...

As a preliminary study for the erection of floating structures using high performance concrete, this paper examines the bond characteristics between concrete and the reinforcing bar. Since the floating structure is constructed in aquatic environment, corrosion of the reinforcing steel is likely to develop more prematurely than in onshore structure in case of concrete cracking. A solution to thi...
