摘    要:试验研究预应力钢绞线在经历高温作用并冷却至室温后的力学性能。考虑不同冷却方式对其性能的影响,得到经历不同高温后钢绞线的极限强度、名义屈服强度、弹性模量和延伸率及其变化规律,给出力学模型。为过火预应力混凝土结构的剩余承载力计算及损伤评估提供依据,具有较高实用价值。

关 键 词:温度  试验  预应力钢绞线  力学性能

Abstract:The material properties of prestressed steel strand post high temperatures are studied by experiments and various cooling patterns are considered in the experiments. The tensile strength, yield strength, modulus of elasticity of prestressed steel strand post high temperatures are obtained. It supplies a basis for the calculation of remainder load bearing capacity and evaluate of damage about the prestressed concrete structure post fire.
Keywords:temperature  experiment  prestressed steel strand  material property
