摘要
通过对预应力钢绞线在不同温度下共 36根实材试件的力学性能试验 ,得到了钢绞线极限强度、屈服强度、弹性模量随温度的变化规律 ,给出了其力学模型 ,为预应力混凝土结构的抗火分析研究提供了依据。
Steel strand is usually used in the prestressed concrete structures.By experiment on material properties of 36 prestressed steel strand members at high temperatures,we obtained tensile strength,yield strength,modulus of elasticity of steel strand at high temperatures and its mechanics models.It supplies the basis for the analysis and study about fire resistance of prestressed concrete structures.
