Abstract: The structure of beamless floor is a common structure used in the underground buildings. We usually adopt the experiential coefficient method and the equivalent frame method in calculation at present. But the assumption of the tvvo calculation methods mentioned above is different from the practice of single layer beamless floor. So the calculating model based on the actual size is established. In accordance with calculating result, the practical distribution of internal force is derived by moment distribution method. The design recommendations are presented by comparative analysis on the data.
