摘　　要：本文采用了一种通过中间的验证性试验来保证刚性固定对接结构拘束度有限元计算的有效性,刚性固定对接结构的拘束度计算结果表明,从焊缝中心到焊缝两端拘束度逐渐变大,在焊缝中间位置处,试板板厚与拘束度近乎成正比例线性关系。The Validity of finite element computation for restrained-butt joint restraint is warranted through the middle proving trial introduced in the paper.The computation results show that the restraint of the weld seam from the centrer to both ends is enlargement gradually.The restrain is proportional linear relationship with the plate thichness at the middle of weld.
