摘要
无梁楼盖是地下建筑中常见的结构形式,目前多采用经验系数法或等代框架法进行计算,两种计算模型与地下单层无梁楼盖结构存在假设差异。以实际工程尺寸建立力学计算模型,根据弯矩分配法推导实际内力分布情况,通过数据对比提出设计建议。
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 two 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.
