提出了一种基于高阶计算连续体(HC2)格式的多尺度板单元，用于分析钢筋混凝土实心板、华夫板和空心板。该公式的显著特点是：(I)能够考虑大的代表性体积单元(RVE)的特性，(Ii)由于易于处理损伤和施加预应力，(Ii)多功能性，以及(Iii)由模型简化产生的计算效率，以及与成熟的损伤律重新缩放方法相结合，得到几乎与网格大小无关的模拟结果。用实心板、空心板和华夫板的试验数据对多尺度公式进行了验证。
We present a multiscale plate element for the analysis of solid, waffle and hollowcore reinforced concrete slabs based on the higher order computational continua (HC2) formulation. The salient features of the proposed formulation are: (i) the ability to consider large representative volume elements (RVE) characteristic to waffle and hollowcore slabs, (ii) versatility stemming from the ease of handling damage and prestressing, and (iii) computational efficiency resulting from model reduction, combined with the well-established damage law rescaling method that yields simulation results nearly mesh-size independent. The multiscale formulation has been validated against experimental data for solid, hollowcore and waffle reinforced concrete slabs with and without prestressing.
