Flexural performance of reinforced recycled aggregate concrete beams
Magazine of Concrete Research, 2012The amount of concrete waste has increased significantly over the years due to reconstruction and the demolition of old buildings. Efforts have been made to utilise recycled aggregates to address some of the environmental problems associated with concrete waste and to promote the sustainability of concrete. A number of studies have been carried out to

The performance comparison of typical notched flexure hinges
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2019Flexure hinges, which serve as the crucial joints in a large number of compliant mechanisms, have been widely applied in a variety of significant fields where there is high demand for the micro/nano motions with high resolution and high precision. Currently, an increasing number of notched flexure hinges with different structures and performances have

Flexural toughness performance of hybrid fiber-reinforced RPC
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2016Flexural toughness tests are performed to investigate the influence of hybrid fibers on the toughness of reactive powder concrete (RPC). The experiment uses different amounts of high-strength steel fibers and macro-polyolefin or micro-polyvinyl alcohol (PVA) fiber.

Flexural performance of hybrid polypropylene–polyolefin FRC composites
Asian Journal of Civil Engineering, 2019The objectives of the present study are to conduct experimental studies and determine the flexural strength and ductility of fiber-reinforced concrete (FRC) by adding two types of fibers, namely the polypropylene (PO) and polyolefin (PP) fibers in mono and hybrid forms, and assess the flexural toughness of fiber-reinforced concrete (FRC).

Flexure Behavior of Hybrid High Performance Concrete Construction
Research, Development and Practice in Structural Engineering and Construction, 2012The recent development of ultra-high performance concrete (UHPC) with excellent material and durability properties has given impetus to seek its application in construction. An exploratory study was undertaken to examine the possibility of utilizing high flexural tensile strength of steel fiber-reinforced UHPC (over 30 MPa) by using a layer of UHPC as ...

Performance of small arrays of flexural disk transducers
The Journal of the Acoustical Society of America, 1976Trilaminar disk elements of small aperture (a = 34 mm) have been used in compact four- and six-element arrays for 2.4-kHz resonant frequency projectors with improved performance over single balanced pair (two-element) projectors of larger (a = 54 mm) elemental aperture.

On the flexural performance of steel beams
2011In this thesis are presented results of different kind of investigation about both monotonic and cyclic behaviour of steel beams. With the aim to quantify the rotation capacity and flexural overstrength of steel beams an experimental activity was performed in the Civil Engineering Laboratory at the University of Salerno in the framework of ReLUIS ...
