%X 蜂窝梁是在H型钢梁的腹板上进行切割、错位焊接而形成的，具有自重轻、抗弯刚度大、造型美观、便于穿越建筑管线、降低层高等特点。开孔导致了梁截面的削弱，使得蜂窝梁的破坏模式趋于复杂。通过文献调研法，总结了蜂窝梁的五种破坏模式以及残余应力对蜂窝梁性能的影响，分析了已有设计计算方法的适用性与局限性，展望了蜂窝梁进一步的研究方向。<br />
Castellated beam is formed by cutting and dislocation welding on the web of an H-shaped steel beam, which has the characteristics of light weight, high bending stiffness, beautiful shape, easy to cross-building pipelines and low story height. Opening holes lead to the weakening of beam section, which makes the failure mode of castellated beam more complicated. Through literature investigation, this paper summarizes five failure modes of castellated beams and the influence of residual stress on the performance of castellated beams, analyzes the applicability and limitations of existing design and calculation methods, and looks forward to the further research direction of castellated beams.
