Concrete Shear Wall Construction
Buildings with cast-in-situ reinforced concrete shear walls are widespread in many earthquake-prone countries and regions, such as Canada, Chile, Romania, Turkey, Colombia, the republics of the former Soviet Union, etc. This type of construction has been practiced since the 960s in urban regions for mediumto high-rise buildings (4 to 35 stories high). Shear wall buildings are usually regular in...
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 کاملUse of Polymer Concrete in Construction
Polymer concrete (PC) is a composite material in which the binder consists entirely of a synthetic organic polymer. It is variously known as synthetic resin concrete, plastic resin concrete or simply resin concrete. Because the use of a polymer instead of Portland cement represents a substantial increase in cost, polymers should be used only in applications in which the higher cost can be justi...
متن کاملOptimal Forest Road Density Based on Skidding and Road Construction Costs in Iranian Caspian Forests
Information on the productivity, costs and applications of the logging system is a key component in the evaluation of management plans for the rehabilitation and utilization of Caspian forests. Skidding and road construction costs are expensive forest operations. Determining the optimum forest road network density is one of the most important factors in sustainable forest management. Logging me...
