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 ... -
The influence of spatial parameters on pedestrian lateral loading.
(BCRI, 2012-09)Dynamic loading from pedestrians walking on flexible structures such as footbridges is the subject of much research at present. The interest is stimulated by several notable instances of uncomfortable perceptible vibrations ... -
Evaluation of corrosion-resistant basalt-fiber-reinforced polymer bars and carbon-fiber-reinforced polymer grid reinforcement to replace steel in precast concrete underground utility vaults.
(Precast/Prestressed Concrete Institute, 2016-09)Underground utility vaults are widely used to house utilities and are conventionally designed using steel reinforcement. These structures are often designed with thicker cover concrete in an attempt to prevent the corrosion ... -
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 ... -
Corrosion resistant reinforcement for sustainable bridges and underground structures.
(ICSECM, 2013-12)Bridge decks and underground service structures are often exposed to extreme environmental conditions where structural damage due to corrosion is a common phenomenon. This results in reduced service life and expensive ... -
Fuzzy‑logic threat classification for multi‑level selective encryption over real‑time video streams.
(Springer, 2020-04-22)This paper proposes a Fuzzy-logic Threat Classification (FTC) model as the basis of a method to auto-detect three different confidentiality levels for videos streamed from heterogeneous, mobile devices via web edge servers, ... -
Ceramic waste sludge as a partial cement replacement.
(CERAI, 2014-08)In this research study, waste ceramic sludge derived from orthopaedic implant mass finishing processes were employed as a supplementary cementitious material (SCM) in the partial replacement of ordinary Portland cement ... -
Alternative reinforcement for lightly loaded concrete structures.
(AJBAS, 2013)Traditionally, high yield steel has been the common method of providing reinforcement in concrete, primarily due to its high tensile strength. However, steel is susceptible to corrosion, particularly in aggressive ... -
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 ... -
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 ... -
Vibration serviceability considerations in footbridge design.
(UniMap/AIT, 2011-06)Modern footbridges are becoming more and more flexible as they are constructed lighter and more slender than ever before. This has led to a vibration serviceability issue with many footbridges, as they can become ‘lively’ ... -
β-Glucan extracts from the same edible shiitake mushroom Lentinus edodes produce differential in-vitro immunomodulatory and pulmonary cytoprotective effects — Implications for coronavirus disease (COVID-19) immunotherapies.
(Elsevier, 2020-05-11)Coronavirus pneumonia is accompanied by rapid virus replication, where a large number of inflammatory cell infiltration and cytokine storm may lead to acute lung injury, acute respiratory distress syndrome (ARDS) and death. ... -
The impact foot landing position (FLP) has on the simulation of medio-lateral pedestrian loading.
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)The issue of Medial-lateral loading from pedestrians has received increased attention from bridge designers and researchers since the London Millennium Bridge incidence 12 years ago where the bridge vibrated excessively ... -
Identification of damage in steel beams using frequency response changes.
(AJBAS, 2013)The issue of structural condition monitoring is becoming increasingly important as the Ireland’s and the world’s civil engineering infrastructure ages. An efficient monitoring process is essential as part of a modern ... -
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 ... -
The influence of selected gait parameters on vertical pedestrian loading.
(Dolnoslaskie Wydawnictwo Edukacyjne, 2011)Walking trials have been carried out on a rigid surface mounted with a force plate in order to determine the influence of selected gait parameters on vertical pedestrian loading. This paper presents the results of this ... -
Vertical crowd load models for vibration serviceability assessment of footbridges
(Civil-Comp Press, 2009)Most pedestrian load models prescribed in existing design codes of practice do not consider any interaction between the pedestrian and the moving structure. However, it is now widely accepted that this interaction is ... -
Interactive horizontal load model for pedestrians crossing footbridges.
(Taylor & Francis, 2007-02-16)In recent years several theories have been put forward in relation to lateral forces imparted on bridges from crowd movements. It is now widely accepted that the interaction between the crowd and the structure, particularly ... -
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, ... -
NetFlow anomaly detection through parallel cluster density analysis in continuous time-series.
(Springer, 2017-06)The increase in malicious network based attacks has resulted in a growing interest in network anomaly detection. The ability to detect unauthorized or malicious activity on a network is of importance to any organization. ...
