Flexural Strengthening of RC Continuous T-Beams Using CFRP
Fibers, 2020 In this paper, experimental investigations for strengthening reinforced concrete (RC) continuous beams were performed. Eighteen T-beams were cast, twelve of which were inverted T-beams where the flange portion of the T-beam was subjected to positive ...

Theoretical and numerical analysis of reinforced concrete beams with confinement reinforcement
Revista IBRACON de Estruturas e MateriaisThis paper discusses the use of confinement in over-reinforced concrete beams. This reinforcement consists of square stirrups, placed in the compression zone of the beam cross-section, in order to improve its ductility.

Ductility Design of High-Strength Concrete Beams and Columns
Advances in Structural Engineering, 2010 High-strength concrete (HSC) is increasingly used for the construction of tall buildings and long span bridges. However, most engineers just focus on how to better utilize the strength potential of HSC and little attention is paid to ensure that the HSC structures would have sufficient ductility.

Ductility of reinforced lightweight concrete beams and columns [PDF]
Latin American Journal of Solids and Structures, 2014 This paper presents analytical and experimental results on ductility of reinforced lightweight concrete beams and columns in the form of moment curvature relationships, and compares the response with that of normal reinforced concrete members. The experimental part is limited to flexural tests on beams made of lightweight concrete.

Ductility and moment redistribution capacity of two-span RC beams
Инженерно-строительный журнал, 2019 The particular weaknesses of concrete buildings are brittle fracture and lack of material ductility, so using steel reinforcements and discrete fibers are an attempt to overcome this weakness.

Electron-Beam Welding of Laser Powder-Bed-Fused Inconel 718
International Journal of Engineering Materials and Manufacture, 2021 This study explores the application of Electron-Beam Welding (EBW) for joining Laser Powder-Bed-Fused Inconel 718 (L-PBF IN718) superalloy. Three different levels of electron beam speed and beam current were explored to give nine different electron beam ...
