摘　　要：结合工程实际,在钢筋混凝土屋面飘板结构设计中,对其悬挑屋檐方案安全问题采用有限元方法进行计算和分析,结果显示,悬挑屋檐板的最大跨度应取4.8 m,梁按变截面设计并不增加悬挑屋檐板的最大位移,在悬挑屋檐板端部内增设几道钢筋,可使悬挑屋檐板的端部位移和应力均匀。Safety of cantilever eaves for reinforced concrete roofing wing panel was analyzed by finite element method with respect to the practical engineering situation. It is indicated that, without altering the design of the change section of beams, even end displacement and stress of cantilever eaves can be maintained by supplementing reinforced steel bars when the maximal span of cantilever eaves is kept within 4.8m while the maximal displacement of cantilever eaves is not increased.
