摘　　要：在CEBMC1990和DeSchutter关于早期混凝土计算理论的基础上,分别建立混凝土早期极限拉应变计算模型,通过对2个模型相互之间及其与试验数据的比较,验证了所建立模型的正确性.该计算模型采用应变判断准则,可应用于在商品混凝土住宅楼板的早期开裂预测及控制.Based on the early age concrete computation theories of CEB MC 1990 and De Schutter, computation models of concrete early-age ultimate tensile strains were established. The reliability of the models proposed in this paper was verified by the comparison between the two models themselves and between the models and test data. The models apply strain criterion, and lay a foundation in predication and control of the early cracking of commercial house floors.
