Description

Technical Field

[0002] Prestressed steel bars are compressive stresses applied to the concrete of structural members by pre-tensioning or post-tensioning before the use of structural members. In ordinary reinforced concrete structures, due to the low ultimate tensile strain of concrete, under the action of service load, the strain of the steel bars in the member greatly exceeds the ultimate tensile strain of concrete. The strength of the steel bars in reinforced concrete members cannot be fully utilized. Therefore, it is unreasonable to use high-strength steel bars in ordinary reinforced concrete structures. In order to make full use of high-strength materials and make up for the gap between the tensile strain of concrete and steel bars, people apply prestressing to reinforced concrete structures.
