  • Non destructive testing of concrete 
    Warusavitarana, LI [Thesis-Abstract]
    Assessment of in-situ concrete, a major building material in construction has been of considerable interest in Construction Industry, mainly for quality control as well as to find in-situ strength. The measurement of ...
  • 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 and physical modelling of cracks in masonry walls due to thermal movements of an overlying slab 
    Dilrukshi, KGS [Thesis-Abstract]
    Concrete slabs exposed to direct sunlight experience temperature related horizontal movements. In addition, temperatures on the top surface will be higher than those on the underside of the slab, causing an upward deflection ...
  • 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 modeling of effect of underground cavities on foundations 
    Maduranga, HR [Thesis-Abstract]
    Simulation of the behavior of foundations over underground cavities and identification of factors affecting the design of the foundations over such cavities are valuable to foundation design engineers. Matale area in the ...
  • Numerical modeling of rock socketed piles 
    Kodagoda, SSI [Thesis-Abstract]
    The two basic types of pile foundations are skin friction piles and end- bearing piles. Friction piles resist the applied vertical load by utilising the shear stresses developed along the pile-soil interface, with the ...
  • Numerical Modeling of Tsunamis for Early Warning and Evacuation 
    Udayakumara, ERS [Thesis-Abstract]
    Its creation was prompted by the 2004 Indian Ocean earthquake and resuhing tsunami, which lel^; some 230,000 people dead or missing. Many analysts claimed that the disaster would have been mitigated if there had been an ...
  • Numerical Modelling and experimental investigation on enhancing punching shear capacity using carbon fiber reinforced polymer on flat slabs 
    Silva MAL [Thesis-Abstract]
    Flat slabs are much vulnerable to shear failures because stress transferring between the column and the slab happens within a considerable small region. This creates high stress at the slab-column connection area result ...
  • 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 ...
  • Numerical modelling of ultra-thin structures in a fluid domain 
    Sanmugadas, V [Thesis-Full-text]
    Folding structures with a large surface area into a compact configuration and deploying them only when required can be achieved by employing origami based folding patterns. This technique is widely seen in nature and ...
  • 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 ...
  • Open source software project management from quality aspects 
    Ranaweera, YM [Thesis-Abstract]
    The breakthrough of Open Source Software Development (OSSD) is not only evident when looking at the gradually rising interest in OSS related research but also when observing the software business. Clearly OSS provides many ...
  • Opportunities and threats faced by urban housing developers 
    Gunasekara MDS [Thesis-Abstract]
    The Sri Lankan construction industry went through a major boost within the last few decades, especially in high rise residential buildings which are coming up in Colombo and other urban areas. The growing number of local ...
  • Optics based low cost full-field in-plane displacement measuring technique 
    Diluxshan, A [Thesis-Full-text]
    Optics Based Low-cost Full-field In-plane Displacement Measuring Technique Displacement/strain measurement plays a significant role in understanding structural and material behaviour. In the local context, commonly used ...
  • Optimal regional planning in solid waste management 
    Katugampola, PI [Thesis-Abstract]
    This study investigates the application of linear programming and mixed integer programming techniques for the optimal allocation of waste stream and facility scheduling of a regional solid waste management system, over ...
  • Optimisation of irrigation water releases in the wet season using probable rainfall 
    Thoradeniya, WBM [Thesis-Abstract]
    Irrigation water has become scarce. The availability is decreasing due to the ever increasing demand for fresh water and the competition between the different uses of it. This scarcity persuades us to introduce improved ...
  • 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 bus dispatching from any given terminal 
    Piyadasa, JDAI [Thesis-Abstract]
    The problems of scheduling and schedule co-ordination have conflicting objectives related to user’s cost, operator’s cost, overloading and crew deployment hours. Passengers would like to have bus service where there is ...
  • Optimization of circular ground reservoirs 
    Wickramasinghe, NRS [Thesis-Abstract]
    Ground reservoirs of various types are often used as water storage reservoirs in major water supply schemes. Mainly there are two types of ground reservoirs viz. circular and rectangular. Circular type ground reservoirs ...
  • Optimization of prestressed concrete railway sleepers 
    Lakmali, HDD [Thesis-Abstract]
    In Sri Lanka cheapest and safest mode of transportation is railways. It has higher load carrying capacities. The load applied by trains is transferred to the ground through rails supported on railway sleepers. Basically ...
