| 摘 要： | 为了提高高层建筑的抗震能力,高层建筑用钢应具有较强的塑性变形一致性.塑性变形一致性主要是通过降低钢的屈强比来实现,因此,屈强比是衡量高层建筑用钢抗震性能的一个重要参数.对不同化学成分的钢进行了控轧控冷试验,得出了化学成分、晶粒尺寸、珠光体和贝氏体的含量及M/A岛状物对屈强比的影响,并且根据试验数据回归出了屈服强度、抗拉强度的计算公式.

| Abstract: | In order to increase the earthquake-resistance of high-rise buildings, the steels used must possess strong consistency in plastic deformation,due to low yield-strength ratio. Therefore, the yield-strength ratio is an important parameter to judge the earthquake-resistance of the steels. The experiments of controlled rolling and controlled cooling for different steel grades were carried out. And the effects of chemical composition, ferrite grain size, content of pearlite and bainite and M/A islands on yield-strength ratio were studied and regression formulas for yield and tensile strength were obtained. |
