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 ... -
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’ ... -
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, ... -
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 ...
