  • Low cost underground water tanks 
    Nanayakkara, VASP [Thesis-Abstract]
    There is a great need to construct low cost underground water tanks in the dry zone of Sri Lanka to enable rain water harvesting .A research is conducted to introduce the said tanks with the use of low cost materials. ...
  • Manual inspection and assessment method of highway bridges 
    Karthika, M [Thesis-Abstract]
    “Inspection and Assessment of bridges” plays an important role, because the resources being spent in keeping existing bridges functioning to the standards for which they were designed are no longer sufficient. There is ...
  • Methodology to identify the optimum network for an urban rail system 
    Malkanthi, LPS [Thesis-Abstract]
    Planning of railway systems is very important in situations of urban Light Rail Transit (LRT) and Mass Rapid Transit (MRT) network development because, these transportation systems not only provides for the mobility of ...
  • Micro simulation model to analyze turning movement delays at road intersections 
    Liyange, LWG [Thesis-Abstract]
    In many countries the transportation planning process is currently turning from the unlimited expansion of the infrastructure to the improvement of the efficiency of the existing systems. This demands the development of ...
  • Modelling of damages in RC structures 
    Kasim, GL [Thesis-Abstract]
    Reinforced concrete is a very versatile and durable building material. Reinforced concrete efficiently combines the best properties of concrete and reinforcing steel into a strong structural element. As a result of this, ...
  • Modelling of shear bond behaviour of composite sections with axial loads 
    De Silva, PSS [Thesis-Abstract]
    In this study, the shear bond behavior of steel and concrete composite beams under axial effects has been investigated using the finite element technique. A comprehensive review of various existing theories and finite ...
  • Modelling of the deployment behaviour of highly compacted thin membranes 
    Liyanage, PM [Thesis-Abstract]
    Space structures such as solar sails, solar reflectors, and sun shields have very large surface areas. Hence they require deployable methods to be stored and transported out of the earth’s atmosphere in limited cargo ...
  • Modelling the relationship between vehicle operating speed and the geometry of the roads using geographic information systems (GIS) 
    Rajapaksha, RPGKS [Thesis-Abstract]
    It is known that road geometric features significantly contributes to the variation in vehicle speed. According to conventional Highway Geometric design procedure there is no accurate method to predict actual vehicle speed ...
  • Nonlinear analysis of cable structures 
    Peiris, HCT [Thesis-Abstract]
    Large structures are widely used in the modem construction industry for infra-structure facilities development. Among these, long span structures with cables are becoming increasingly popular. In this category of structures ...
  • Numerical implementation of a constitutive model for soil creep 
    Madurapperuma, MAKM [Thesis-Abstract]
    Multi-dimensional (2-D and 3-D) soil creep models creep model (Bjerrum, 1967), which is based expression for creep strain rate, and are generalized from Bjerrum’s 1-D on field test data. This model is based later modified ...
  • Numerical modelling of axially loaded piles in layered media 
    Bawa, MTA [Thesis-Abstract]
    Numerical analysis of axially loaded piles in stratified soil media has been carried out by using a simple interface finite element based on the principle of linear elasticity to model shear stress transfer at the pile-soil ...
  • On the application of data assimilation in regional coastal models 
    Torre, RC [Thesis-Abstract]
    Data assimilation is a methodology which can optimise the extraction of reliable information from observations and combine it with, or assimilate it in, numerical models. The development of both the observation techniques ...
  • Optimization of biogas production with water hyacinth 
    Dilhani, JAT [Thesis-Abstract]
    The water hyacinth (Eichhornia crassipes [Mart.] Solms) due to its high growth rate and vegetative reproduction has been classified as an obnoxious freshwater weed especially in the tropics and subtropics. It has been ...
  • Optimization of truss type steel bridges 
    Karunarathna, WWN [Thesis-Abstract]
    This work aims towards analyzing truss type steel bridges by 3-D finite element modelling using SAP2000. Details of different truss type steel bridges are discussed together with gathered information on such bridges found ...
  • Optimum logistic cost cluster size of multiple facilities and server systems 
    Perera, KPH [Thesis-Abstract]
    Demand for a particular facility can be exceeded due to the continuous growth of consumers. Therefore the existing competition can also be increased. This will boost the forming of new facilities providers and also increase ...
  • Peaty clay improvement with prefabricated vertical drains 
    Kugan, R [Thesis-Abstract]
    Peaty clay obtained from the Colombo-Katunayake Expressway route was tested in the laboratory for its consolidation characteristics. The main objective was to quantify the improvement in peaty clay by the use of pre-fabricated ...
  • Performance indicators for the highway network in Sri Lanka 
    Weerawardana, WJ [Thesis-Abstract]
    Highway construction projects go through several processes such as appraisal, design, planning and construction before they reach the operational stage where the project goals intended at the beginning of the project are ...
  • Performance of green roofs in tropical climatic conditions 
    Wijerathne, SN [Thesis-Abstract]
    Growth ofthe world urbanization has been extensively accelerated since past few decades. With the increasing urbanization, the land with permeable layers and moist have been altered. As a result, urban heat island phenomenon ...
