Enhancement factors for the vertical response of footbridges subjected to stochastic crowd loading.
(Elsevier, 2012-07)
The vertical acceleration response of a hypothetical footbridge is predicted for a sample of single pedestrians and a crowd of pedestrians using a probabilistic approach. This approach uses statistical distributions to ...
Oat husk ashes as supplementary cementitious material
(Technological University of the Shannon Midlands Midwest, 2022)
Supplementary cementitious materials (SCMs) are recognized and utilized to minimize cement use; however, several waste sources now employed for partial cement replacement are under threat for changes in industrial production ...
Preliminary characterisation of natural fibres for enhancement of concrete
(Athlone Institute of Technology, 2018-04-24)
Reinforced concrete with steel is one of the most used construction materials in the world. The addition of short bio-based fibres into the concrete mixture for the production of elements lightly loaded can avoid concrete ...
Characterisation of natural fibres for enhancement of concrete properties.
(OJS/PKP, 2019-06)
The use of fibres as reinforcement of composites is widely applicable for mechanical, materials and construction sectors. For instance, most of those fibres are not produced from renewable sources or by ecological procedures ...
Lateral loads applied by pedestrians at normal walking velocities.
(Taylor & Francis, 2011)
The issue of horizontal loading from pedestrians has received increased attention from bridge designers and researchers
in the past decade, primarily due to notable instances of excessive vibration of structures subjected ...
Measurement of time-dependent colour variation in concrete.
(BCRI, 2012-09)
The phenomenon of colour variation in finished concrete has become a contentious issue in recent years as engineers
and designers strive, not only for blemish free finishes, but crisp “white” concretes with uniformity ...
Modelling the vertical loads applied by pedestrians at a range of walking velocities.
(AJBAS, 2013)
Over the past half century numerous high profile bridges such as the Brooklyn Bridge, the London Millennium Bridge, and the Auckland Harbour Bridge have been subject to pedestrian induced vibrations due to walking. In this ...
Use of natural fibres to enhance tensile strength of concrete.
(ICBBM, 2017-06)
This paper discusses the influence of natural fibres on density, compressive strength and
flexural strength of fibre reinforced concrete specimens. Coir fibre extracted from coconut husk
was added to high strength concrete ...
Interaction between pedestrian loading and vibration response of a laboratory-scale FRP composite footbridge.
(Bridge Engineering Association, 2017-08)
Pedestrian loading on flexible structures such as footbridges, grandstands and lightweight floors is an area, which is receiving significant attention from the research commu-nity of late. One of the key parameters in ...
Transient response simulation of a composite material footbridge to crossing pedestrians.
(CRC Press, 2003)
Loads applied by pedestrians, and crowds of pedestrians, are particularly important for footbridges with natural frequencies close to footfall frequencies of moving pedestrians. Recorded response data from Aberfeldy Bridge, ...
