معیارهای طراحی خطوط لوله بر اساس کرنش

Traditional pipeline design analysis methods presented in various codes are usually based on limit stress criteria. However, these methods may be inapposite to modern steels, especially for displacement controlled loads such as ground displacement load. Strain limits, including ovalization limit, tensile strain limit and compression strain limit, are compared in this paper based upon various codes and recommendations. In addition, most factors of strain limits are also reviewed respectively.
