• Applications of high strength concrete in highrise buildings 

  Jayasinghe, MTR; Jayanandana, ADC; Alwis, KGNC [Conference-Full-text]

  High strength concrete can be used in high-rise buildings to minimise the size of columns, especially in the lower floors. High strength concrete has the added advantage of a higher elastic modulus that can reduce the ...
• Wind loads for high-rise buildings constructed in Sri Lanka 

  Jayasinghe, MTR; Jayathilake, SAVSW; Perera, KAAA; Wickramasinghe, P [Conference-Full-text]

  In the design of high-rise buildings, it is of paramount importance to control the wind induced accelerations of the buildings to acceptable limits so that the majority of occupants will not feel the wind induced movements ...
• Earthquake design techniques for Sri Lanka 

  Jayasinghe, MTR; Kulatilake, SAS; Alwis, KGNC; Angammana, RB; Perera, GDTS [Conference-Full-text]

  Two major factors discourage the introduction of seismic resistant design to low seismic regions like Sri Lanka. They are the cost associated with improved seismic resistance and the misconception that the area concerned ...
• Passive solar techniques for Sri Lanka 

  Jayasinghe, MTR; Sujeewa, LC; Fernando, KKJS; Wijayapriya, RA [Conference-Full-text]

  Passive solar architecture can be described as the utilisation of the energy of the sun together with the characteristics of the local climate to directly maintain thermally comfortable conditions in buildings while ...
• Integration of cost control and estimation using Spreadsheets and databases 

  Kodikara, GW [Conference-Full-text]

  Cost control is very important for any industry, since it is the activity which monitors the actual cost against the budgeted costs and initiates corrective actions if the costs are higher than expected. The estimating ...
• Design and construction of horizontal axis wind mill For water pumping 

  Balasuriya, PD; Nimal, RP; Pathirana, CR; Sugathapala, AGT [Conference-Full-text]

  This paper presents design and construction details of a six-bladed horizontal axis wind mill suitable for small scale lift irrigation. The main outcome of the study is the improvement of the rotor performance by ...
