摘要
根据国标中建筑结构设计标准和钢结构设计新规范.对井架构件截面进行了极限状态设计,将有限元分析与可靠性的方法相结合,对井架截面的可靠性进行了评价,并在给定的可靠度下进行了井架构件截面设计.提出了相对实用的井架构件截面可靠性设计模式和具体的设计方法.实际计算表明,该设计方法有较好的可行性.
According to the new national design standards of steel structure, the cross-section design of derrick components is discussed. The reliability of cross-section of JJ 250/42-K derrick is evaluated by combining the finite element method with reliability method. Some component cross-sections were designed under the given reliability indexes. The practical modes for cross-section reliability designs are given. A example of calculation shows the possibility of the method.
