    Aaruga, S; Chandrathilaka, ERK; Gamage, JCPH [Conference-Abstract]
    A numerical model was developed to investigate the flexural performance of Carbon Fibre Reinforced Polymer (CFRP) strengthened concrete curved beams subjected to outof- plane bending. In this study, near surface mounted ...
  • Finite element simulation of thin folded membranes 
    Dharmadasa, BY; Mallikarachchi, HMYC [Conference-Abstract]
    Deployable gossamer structures use thin filmed membranes folded into different patterns. Predicting the membrane behaviour and the stress propagation in these structures is complex due to non-linear characteristics at ...
  • Finite volume analysis of biomass particle pyrolysis 
    Perera, KUC; Narayana, M [Conference-Abstract]
    Individual biomass particle exchanges mass and heat with its surrounding during the thermal conversion process. Therefore environmental conditions around the particle greatly determine the conversion process through which ...
  • Finite-element model approach to determine support conditions and effective layout for concrete block paving 
    Mampearachchi, WK; Gunarathna, WPH [Article-Full-text]
    Concrete block paving CBP is one of the predominant road construction methods used in most of the developing counties due to its economic adaptability. It has emerged as a cost-effective road construction method suitable ...
  • Fire performance analyses of modular wall panel designs with loadbearing SHS columns 
    Perera, D; Upasiri, IR; Poologanathan, K; Perampalam, G; O’Grady, K; Rezazadeh, M; Rajanayagam, H; Hewavitharana, T [Article-Full-text]
    Modular Building Systems (MBS) are still in the phase of developing its popularity in the industry, with emerging novel designs. Initially, MBS walls and floors had been highly influenced by the Light-gauge Steel Frame ...
