摘　　要：对钢筋混凝土板分层有限元非线性分析方法进行了研究．将钢筋混凝土离散成矩形单元，并沿板厚方向再将极分割为五层，考虑混凝土在双向受力下的非线性性能，对四角铰支、跨中承受集中荷载的Ｇ．Ｍ．ＭｃＮｅｉｃｅ双向极进行了全过程计算．结果表明，计算的荷载－挠度曲线与试验结果比较吻合．This paper presents a layered finite element incremental procedure to predict the behaviors of reinforced concrete slabs in the pre-and post-cracking range. During the analysis, concrete and steel layers are divided into rectangular elements. The two-way square reinforced concrete slab, supported at the four corners and subjected to a concentrated load in the center, is calculated by means of this method. computed load-deflection curves show reasonable agreements with the tested results.
