K型铸钢节点静力性能研究

Research on Stastic Performance of Cast Tubular K-joints

本文利用ANSYS对K型铸钢节点与钢管相贯节点在强度上进行了对比，对K型铸钢节点进行了弹塑性大应变分析。通过合理的设计，可使K型铸钢节点只在与钢管连接接口处发生轴向屈服破坏，避免了一般K型相贯节点的过度变形破坏和冲切破坏，提高了节点的安全度。

Comparison on strength of cast tubular K-joints and tubular K-joints by ANSYS software, this paper analyses the large strain and elastoplastic of cast tubular K-joints. Axial yield failure will take place only at tubular interface of cast tubular K-joints. So by means of reasonable design, seriously deformation damage and punching damage of general tubular K-joints will be avoided, and safety of joints will be enhanced.
