متن کاملCrack Resistant Concrete Material for Transportation Construction
Most transportation infrastructures are exposed to a combination of mechanical and environmental loads. Normal concrete is brittle and tends to crack, resulting in a lack of durability and frequent repair needs. This paper describes an ultra ductile cementitious composite which is highly crack resistant, with a tensile strain capacity over three hundred times that of normal concrete. Apart from...
متن کاملSemantic 3D CAD and Its Applications in Construction Industry - An Outlook of Construction Data Visualization
In response to the need of using electronic design data directly in construction management applications, many CAD developers have started implementing semantic data models in their CAD products using industry foundation classes (IFCs). While helpful, these semantic CAD applications have limitations when used in actual construction practices. The case studies in the thesis indicated that: 1) th...
