通常确定高强度钢设计应力使用的设计规范是以屈服应力或抗张强度的百分数为依据的。只要钢内无裂纹和缺陷,在此应力下使用构件不会发生故障。但是,现时的观点认为,不可能得到完全没有裂纹而又均匀的材料。因为在使用中 The design specifications used to determine the design stress for high strength steels are generally based on the percent yield stress or tensile strength. As long as there are no cracks and defects in the steel, the use of components under this stress will not fail. However, the current view is that it is impossible to obtain a completely crack-free and homogeneous material. Because in use
