摘要
设计制作了三根蜂窝梁进行试验 ,根据所得试验数据 ,分析了圆孔和六边形孔两种孔型蜂窝梁的整体受力性能、截面应力分布和承载能力 ,发现圆孔蜂窝梁的承载能力高于六边形孔蜂窝梁 .通过对简化计算理论值与实测值的对比分析 ,验证了简化计算的正确性 ,总结出了两种孔型蜂窝梁的设计计算方法 .
Three castellated beams were designed and tested. Ba sed on the obtained experimental data, the mechanical behavior, sectional stress distribution and loading capacity of the tested circular-hole and hexagon-hol e castellated beams were analyzed. It is found that the loading capacity of the circular-hole castellated beam is greater than the hexagon-hole one. Moreover, the correctness of the reduced calculation is verified by the comparison betwee n the theoretical values obtained by the reduced calculation and the tested valu es. Thus, the design methods of the two castellated beams are given.
