现浇钢筋混凝土连续式结构不设伸缩缝的设计方法

Design meghod on Continuous Structure for Cast-in-site Reinforcement Concrete without Expansion Joint

结合具体工程,阐述了现浇钢筋混凝土连续式结构不设伸缩缝的理论依据,论述了UEA(硫铝酸钙类膨胀剂)补偿混凝土的抗裂机理,从设计、技术、施工方面对不设永久伸缩缝提出了有效控制裂缝的措施。

In combination with concrete project, theoretic basis was described for the continuous structure for cast-in-site reinforcement concrete without expansion joint, anti-crack mechanism was discussed for UEA （aluminium calcium sulfate swelling agent） compensate concrete, measure for effectively controlling crack was presented for concrete without permanent expansion joint from aspects of design, technique, construction.
