蜂窝梁是一种新型的钢结构构件,抗弯性能好、成本低。通过在均布荷载作用下六边形开孔简支蜂窝梁的挠度分析方法,推导了费氏空腹桁架法和改良费氏空腹桁架法。同时应用 ANSYS分析软件对影响挠度的孔高比、距高比和跨高比等因素进行了分析,结果表明:简化计算公式与有限元分析结果吻合较好,能满足工程应用要求。
This paper presents the analytical solution for determining the bending and shear deflections of castellated beams subjected to a uniformly distributed transverse load .To validate the derived analytical solution , which diameter-depth ratio, space-depth ratio and span-depth ratio are considered , three-dimensional linear finite element analysis is performed using four-node shell elements built-in ANSYS software .Good agreement between the finite element result and the present analyt -ical solution is demonstrated .
