The aim of this study is to investigate the effects of non-Newtonian blood rheology models on the wall shear stress (WSS) distribution in a cohort of patients-specific coronary arteries. Twenty patients with diseased left anterior descending (LAD) coronary arteries (with varying degrees of stenosis severity from mild to severe) who underwent angiography and in-vivo pressure measurements were se...

This paper reports the findings of research examining the blast resistance of bridge piers that are designed in accordance with current knowledge and specifications to ensure ductile seismic performance. Blast testing was conducted on 1/4 scale ductile RC columns, and nonductile RC columns retrofitted with steel jacketing. The seismically designed RC and steel jacketed RC columns did not exhibi...

Shear walls are important vertical and lateral bearing element in structures. While shear with openings fragile due to stress concentration the quasi-brittle behavior of concrete tension. Therefore, additional strengthening rebars required for openings. However, it aggravates problem dense reinforcement which increases steel cage manufacturing compaction still lacks countermeasures against dama...

This study develops three-dimensional (3D) finite element (FE) models of composite retrofits in deficient reinforced concrete (RC) columns and frames. The aim is to investigate critical cases RC with inadequate lap splices bars or corroded steel reinforcements the beneficial effects external FRP jacketing avoid their premature failure structural collapse. Similarly, RC-frame FE explore an innov...

This study focused on characteristic cases of recently tested real-scale RC framed wall infilled structures with innovative seismic protection through polyurethane joints (PUFJ) or polyurethane-impregnated fiber grids (FRPU). The frames revealed a highly ductile response while preventing infill collapse. Herein, suitable 3D pseudo-dynamic FE models were developed in order to reproduce the exper...

Abstract This paper examines the optimal placement, numbers, and shape of Buckling Restrained Braces (BRB) for a 3D shear-wall frame building structure based on linear static analysis utilizing ETABS software. The total amount BRBs referred to as number are considered design variables objective function be minimized is maximum story displacement inter-story drift. diagonal (D), X-shape (X), V-s...

A diffuse interface method is used to simulate two-phase flows with moving contact lines in 3D. The specific numerical issue is the validation of the method regarding the dynamics of moving contact lines in 3D. In particular, we aim to use the method to extend previous (2D and/or creeping-flow) work on sheardriven motion of a droplet on a wall to the full 3D problem, accounting for inertial eff...
