摘　　要：基于ANSYS有限元分析软件,对大跨度钢-混凝土正六边形蜂窝型空腹夹层楼盖结构进行了静力分析,研究了剪力键高度对其静力承载力的影响。结果表明,最大挠度发生在楼盖跨中附近。针对特定模型,在只改变剪力键高度的条件下,利用有限元方法进一步研究了剪力键高度对该楼盖承载力的影响。结果与分析表明,随着剪力键高度的增加,楼盖高度增加,其刚度提高;但当剪力键高度增加到一定程度后,继续增加剪力键高度对楼盖承载力的提升增益不高。By using ANSYS finite element analysis software,a static analysis has been made of the long-span steel-concrete hexagonal honeycomb hollow sandwich floor structure,followed by a study on the influence of shear key height on its static bearing capacity.The results show that the maximum deflection occurs near the mid span of the floor.Subsequently,a further study is to be carried out of the influence of shear key height on the bearing capacity of the floor by using the finite element method under the condition of sole change of the shear key height intended for a specific model.The results and analysis show that with the increase of the shear key height,the floor height increases,and the stiffness is improved;while with the shear key height increasing to a certain extent,the increase of the shear key height on the floor bearing capacity is not so noticeable.
