    Perera, MUD; Dilrukshi, KGS [Conference-Full-text]
    The use of limestone in the construction industry has been increasing due to its potential as aggregate. Some of the benefits of limestone include good strength, low possibility of alkali-silica reaction and the decrease ...
  • Engineering Solutions To Minimize Delays And Safety Risk At Dehiwala Flyover 
    Yahampath, B; Bandara, S; Perera, L [Conference-Full-text]
    Traffic congestion is one of the most imperative problems in almost all countries. Flyovers are usually used all over the world to address the traffic congestion, especially at intersections. Advantages of grade separation ...
  • Evaluation Of Seismic Performance Of Existing Reinforced Concrete Buildings In Sri Lanka Using Pushover Analysis Approach – A Case Study 
    Milinda, ALDN; Lewangamage, CS [Conference-Full-text]
    Evaluation of seismic performance of existing buildings is vital to reduce their seismic vulnerability. Performance can be evaluated by the interaction between structure’s capacity and the probable seismic demands. After ...
  • Hydraulic Performance Of Rubble Mound Breakwaters 
    Hettiarachchi, SSL; Odara, MGN; Godagedara, TH; Herath, HHHB [Conference-Full-text]
    Breakwaters are widely used to mitigate the adverse impacts of ocean wave action. Breakwater failures that occurred during late seventies and early eighties, have highlighted the need for further investigations on breakwaters ...
  • Investigation Of Movements In Block Masonry Walls 
    Nandapala, K; Peiris, A; Senavirathna, R; Nanayakkara, D [Conference-Full-text]
    One of the main concerns in block masonry is cracking, mainly due to thermal and moisture movement. There are some standards which give guidelines and recommendations to control cracking, but these cannot be directly used ...
  • Investigation Of The Properties Of Limestone Concrete 
    Hemadasa, MBC; Dilrukshi, KGS [Conference-Full-text]
    More than seventy percent of the volume of concrete is occupied by aggregates. Aggregates with undesirable qualities will have an adverse effect on durability and structural performance of concrete. Though gneiss is normally ...
  • Local Construction Companies And Mega Projects: Foreign Presence In The Srilankan Construction Industry 
    Jayasooriya, NK; Ekanayake, L [Conference-Full-text]
    The Sri Lankan Construction Industry has been booming for the past few years, with the emergence of several mega projects. Mega Projects are currently led by foreign consultancy and construction companies with the foreign ...
  • Modelling Of Structural Failures In Rc Beam Elements Using Ansys 
    Rokilan, M; Baskaran, K [Conference-Full-text]
    Simulation of failures using laboratory experiments will be expensive and time consuming. To overcome these problems making use of finite element methods and advantages of computational software are key considerations. ...
  • Pros And Cons Of Using Structurally Insulated Panels In Sri Lanka 
    Jayathilake, L; Baskaran, K [Conference-Full-text]
    Structurally Insulated Panels (SIPs) are extensively used in energy efficient buildings all over the world. SIPs can be simply introduced as a building material consisting of an insulating layer in between two structural ...
  • Rapidly Deployable Structures For The Tourism Industry In Sri Lanka 
    Mustapha, MSN; Lewangamage, CS; Thompson, LM [Conference-Full-text]
    This research involves the concept of creating rapidly deployable ecofriendly cabanas for the tourism industry in Sri Lanka. The cabanas are to be pre-fabricated; thus could be purchased off the shelf and assembled at site. ...
