  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Diluxshan, A [Thesis-Abstract]
    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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Santhajeewa, AN [Thesis-Abstract]
    The conventional earth retaining structures built using Random Rubble Masonry (RRM) are designed as gravity retaining structures where weight of the structure is used for its stability. In Sri Lanka, RRM retaining walls ...
  • Ariyarathne, NGR [Thesis-Abstract]
    ABSTRACT Spillway is a critical component in a storage reservoir or in a diversion dam. Many failures of dams have been caused by improperly designed spillways or by spillways of insufficient capacity. There have been ...
  • 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 ...
  • Gunasena, UPP [Thesis-Abstract]
    Transmission tower lines using lattice towers and concrete foundations are the common practice in most of the countries all over the world. A significant amount of the cost of the transmission tower line is spent for the ...
