Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Effect of hydrogen embrittlement on mechanical properties of non-stressed prestressing steel
Acta Polytechnica CTU ProceedingsThe aim of this paper is to elucidate the effect of hydrogen on the structure of commonly used prestressed concrete steel strand (PC strand) of concrete bridges and other structures in the non-stressed state to determine the general behaviour of the ...

Investigation of Subpanel Size Effect on Behavior Factor of Stiffened Steel Plate Shear Wall [PDF]
Journal of Structural and Construction Engineering, 2019 Steel plate shear wall (SPSW) systems have been used in recent years in highly seismic areas to resist lateral loads. In general, a steel plate shear wall system consists of a steel plate wall, boundary columns, horizental floor beams and optional ...

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Probabilistic assessment of steel moment frames incremental collapse (ordinary, intermediate and special) under earthquake [PDF]
Journal of Structural and Construction Engineering, 2017 Building collapse is a level of the structure performance in which the amount of financial and life loss is maximized, so this event could be the worst incident in the construction.
