BuildingsThe behavior factor, which represents the force reduction that a structure would experience if its response was completely elastic compared with the seismic forces used for design, is defined in seismic design codes for common construction techniques and

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Numerical measures of the degree of non-proportionality of multiaxial fatigue loadings [PDF]
Fracture and Structural Integrity, 2015 The influence of the non-proportional loadings on the fatigue life depends on the material ductility. Ductile materials react with a shortening of lifetime compared to proportional loading conditions.

Shake table investigations on code non-compliant reinforced concrete frames
Alexandria Engineering Journal, 2020 Shake-table tests were performed on a code conforming and four non-compliant 1:3 reduced scale two-story RC frames. The models were subjected to 1994 Northridge earthquake acceleration time history, linearly scaled to multiple levels for studying the ...

Alternative procedure to determine the response reduction factor for ductile RC framed buildings
Gaceta Técnica, 2018 The seismic design is based on the results of the structures elastic analysis, even though now days the nonlinear analysis is increasingly accessible. To perform the seismic analysis of structures that are modeled with elastic behavior, but known to venture into the plastic behavior, the standards establish the reduction of the elastic design spectra ...

Advanced Engineering Materials, EarlyView.Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...

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 ...
