针对节点域强度变化对H型钢柱梁节点力学性能影响的不明确性,本文以节点域强度为主要研究参量,制作5组H型钢柱梁节点试件,通过加载试验和有限元分析,研究不同节点域强度试件(模型)的承载力、刚度、变形、应变及变形贡献率等性能.结果表明:随着节点域强度提升,试件的最大承载力和初始刚度增大,但是变形能力下降;Rpb<0.8时,试件变形主要集中在节点域;而节点域强度最高的试件,其梁变形最大,梁翼缘和腹板在过焊孔附近出现应变集中;且随着节点域强度增大,分析模型的梁腹板承担剪力增大,梁翼缘承担剪力减小,但是梁分担的剪力比例增加;当模型处于弹性状态时,梁的变形贡献率比节点域大;而模型塑性变形后,Rpb<0.8的模型中,节点域的变形贡献率更大,其他模型中梁的变形贡献率更大.
