摘　　要：根据单面粘钢加固混凝土梁的相关试验研究和实际楼板加固需要,首次提出了双面粘钢加固混凝土楼板技术,结合截面内力平衡关系及求解受弯构件刚度的经典理论,并考虑加固过程中楼板未完全卸载的情况,建立了双面粘钢加固楼板的抗弯承载力与截面刚度计算公式,同时给出两种改善钢板与楼板之间粘结效果的构造措施。Based on related experiments research of RC beam strengthened with unilateral steel-slab-bonded and practical engineering needs, the technique of RC floor strengthened with bilateral steel- slab-bonded. According to section internal force equation relation and classical theory about bended component rigidity, and considering of RC floor which is not uninstalled completelyduring strengthened process, the formula of flexural capacity and section rigidity are established about FC floor strengthened with bilateral steel-slab-bonded. Two types of detail measures are given for improving the bonded effect between steel board and RC floor slab.
