Effect of CFRP Strips Orientation on Performance of Strengthened Deep Beams

Al-Qadisiyah Journal for Engineering Science, 2019
This study was carried out in order to explore the behaviour of RC deep beams strengthening with CFRP strips. Eight simply supported deep beams were fabricated and tested under four-points loading scenario.

Localized shear and distributed strain accumulation as competing shear accommodation mechanisms in crustal shear zones: constraining their dictating factors [PDF]

Solid Earth
Understanding the underlying mechanisms of strain localization in the Earth’s lithosphere is crucial for explaining the mechanics of tectonic plate boundaries and various failure-assisted geophysical phenomena, such as earthquakes.

Investigations on the Shear Mechanism of Steel-Tube-Reinforced Concrete Shear Walls with a Low Shear-Span Ratio

KSCE Journal of Civil Engineering, 2019
This paper describes the study of steel tube reinforced concrete (STRC) shear walls with a low shear-span ratio, in which steel tubes are embedded in the web of the shear wall. The addition of these steel tubes can significantly improve the shear behavior of ordinary RC shear walls. A series of cyclic loading tests allow us to examine the failure mode,

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

EFFECT OF SHEAR SPAN RATIO ON THE FRACTURE OF DEEP BEAMS

Doboku Gakkai Ronbunshuu E, 2006
せん断スパン比(以下，a/d)が小さく，せん断補強筋を有するディープビーム部材を対象に，a/d，せん断補強筋比，有効高さをパラメータとして，単純梁を用いた鉛直載荷実験を行い，せん断抵抗に関する検討を行った．その結果，a/d≦1.0とa/d=1.5では終局時の破壊の形態が異なることが，デジタルカメラやひずみの計測を詳細に行うことにより明らかとなり，a/d≦1.0のせん断破壊では，圧縮力が主体となるためせん断補強筋はほとんど効果を発揮しないが，a/d=1.5ではひび割れ幅の抑制効果があることからせん断補強筋が十分に効果を発揮することが分かった．また，本研究におけるせん断耐力評価式は実験値を概ね評価できることが分かった．
