FLEXURAL DUCTILITY OF LIGHTWEIGHT-AGGREGATE CONCRETE BEAMS
JOURNAL OF CIVIL ENGINEERING AND MANAGEMENT, 2016 This paper describes an experimental study on the flexural ductility of lightweight-aggregate concrete beams including concretes with compressive strengths between 22.0 and 60.4 MPa and dry densities between 1651 and 1953 kg/m3. Nineteen simply supported beams were tested until failure. Two symmetrical concentrated loads were applied at approximately

A Parametrical Analysis for the Rotational Ductility of Reinforced Concrete Beams [PDF]
The Open Civil Engineering Journal, 2013 The assessment of the plastic rotation of reinforced concrete beams is an essential aspect to avoid structural brittle collapses. The value actually available can be generally determined as sum of two different components. The first, due to bending, the second for inclined shear cracks. This paper presents a simplified model which provides the flexural

Ductility Enhancement of Post-Northridge Connections by Multilongitudinal Voids in the Beam Web
The Scientific World Journal, 2013 Since the earthquakes in Northridge and Kobe in 1994 and 1995, respectively, many investigations have been carried out towards improving the strength and ductility of steel beam to column pre- and post-Northridge connections.

Seismic performance evaluation of Egyptian code-designed steel moment resisting frames
HBRC Journal, 2018 Despite the fact that steel is a ductile material, the significant damage, during earthquake events, highlighted the need to thoroughly investigate the seismic performance of steel structures.

On the Ductility of High-Strength Concrete Beams [PDF]
International Journal of Concrete Structures and Materials, 2008 Ductility is important in the design of reinforced concrete structures. In seismic design of reinforced concrete members, it is necessary to allow for relatively large ductility so that the seismic energy is absorbed to avoid shear failure or significant degradation of strength even after yielding of reinforcing steels in the concrete member occurs ...

Nonlinear fracture mechanics investigation on the ductility of reinforced concrete beams [PDF]
Revista IBRACON de Estruturas e Materiais, 2010 In the present paper, a numerical algorithm based on the finite element method is proposed for the prediction of the mechanical response of reinforced concrete (RC) beams under bending loading. The main novelty of such an approach is the introduction of the Overlapping Crack Model, based on nonlinear fracture mechanics concepts, to describe concrete ...

Ductile Moment-Resisting Timber Connections: A Review
Buildings, 2022 In the last two decades, high-rise timber buildings have been built using the glulam truss system, even with limited openings. Moment-resisting timber frames (MRTF) with semi-rigid beam-to-column connections can be an architecture-friendly way to provide

THE FLEXURAL STRENGTH AND RIGIDITY OF ALBASIA NAIL-LAMINATED BEAM
Journal of the Civil Engineering Forum, 2012 The horizontally and vertically nail-laminated beams were tested in this experimental study. Twelve specimens of horizontally nail-laminated beam with the same cross section and variation of four nail spacings were tested.

Effect of Intermediate Stiffeners on the Behaviors of Partially Concrete Encased Steel Beams
Advances in Civil Engineering, 2018 Partially concrete encased steel (PE) beams are composite steel beams and concrete elements that present several advantages, such as higher fire resistant, higher flexural capacity, and higher lateral torsional buckling resistant compared to bare steel ...
