It is found that the design of reinforce-beam section dog-bone connection can transfer the yielding joint from flange welds to parent metal zone, which possesses better plasticity and avoid yielding joints in weak welds. This design also enables beam flanges to dissipate earthquake energy more effectuality and protects weak welds.

在弹性、弹塑性有限元分析的基础上，对狗骨式节点和翼缘增强狗骨式节点进行了承载能力对比分析，结果表明：翼缘增强狗骨式节点设计可以将梁柱翼缘焊缝的塑性铰有效的转移到塑性好的母材区域，避免了在薄弱的焊根部位形成塑性铰，保护了韧性较差的焊缝。
