Определение öngerilmeli beton в Турецкий язык Английский Язык словарь: prestressed concrete; concrete with stresses induced in it before use so as to counteract stresses that will be produced by load; often contains stretched steel bars or wires called tendons; A development of ordinary reinforced concrete The reinforcing steel is replaced by wire cables in ducts; Reinforced concrete in which internal stresses have been introduced to reduce potential tensile stress in concrete resulting from loads; concrete in which cracking and tensile forces are greatly reduced by compressing it with tensioned cables or bars; Concrete that has been pretensioned or posttensioned; Concrete reinforced by either pretensioning or posttensioning, allowing it to carry a greater load or span a greater distance than ordinary reinforced concrete. In pretensioning, lengths of steel wire or cables are laid in the empty mold and stretched. The concrete is placed and allowed to set, and the cables are released, placing the concrete into compression as the steel shrinks back to its original length. In posttensioning, the steel in the concrete is stretched after the curing process. Prestressing places a concrete member in compression; these compressive stresses counteract the tensile bending stresses of an applied load. The process was developed by the French engineer Eugène Fressinet in the early 20th century; Structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in concrete resulting from loads
