结构可靠性

• The probability of metallic structures is also a vital factor that affects the structures " safety , so some researches are taken on the probability of metallic structures in this paper , and finite element method is applied in probability analysis successfully
  而金属结构的可靠性也是影响结构安全性的一个非常重要的因素，所以在本文中对起重机的金属结构可靠性也进行了一些研究工作，实现了可靠性分析在有限元中的应用。
