    • Measurement of time-dependent colour variation in concrete. 

      Deegan, Peter; O'Connor, Alan; Archbold, Paul (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 ...
    • Nonlinear finite element of FRP reinforced concrete structures. 

      Tharmarajah, Gobithas; Archbold, Paul (BCRI, 2012-09)
      reinforcement is a non-corrosive alternative to steel and is gaining popularity for use in reinforced concrete structures exposed to corrosive environments. A major difference between the two reinforcing materials is their ...
    • A parametric study of pedestrian vertical force models for dynamic analysis of footbridges. 

      Archbold, Paul; Keogh, Joseph; Caprani, Colin C.; Fanning, Paul (2011-10)
      Footbridge vibration has received much attention in recent years. However, stochastic models for crowd loading are not common, and estimation of crowd-induced vibration is typically done through enhancement factors applied ...
    • Use of natural fibres to enhance tensile strength of concrete. 

      Seneviratne, R.A.C.J.; Tharmarajah, G. (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 ...
    • Variations in vertical loading from walking due to surface vibration. 

      Archbold, Paul; Mullarney, Brian; Carrig, Mirivano (Hemming Information Services, 2014-07)
      Walking trials have been carried out on rigid and flexible walkways mounted with a force plate in order to determine how vertical pedestrian loading is influence by these two walking platforms. This paper presents the ...
    • Vertical crowd load models for vibration serviceability assessment of footbridges 

      Archbold, Paul (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 ...
    • Vibration serviceability considerations in footbridge design. 

      Mullarney, Brian; Archbold, Paul (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’ ...
