Abstract:Development and application of cast-in-situ concrete hollow floor in engineering were introduced. Norms and construction drawings for cast-in-situ concrete hollow floor were summarized. Based on norms, understanding and suggestion were provided for the structural system selection of cast-in-situ concrete hollow floor structure. Several key problems in the engineering application of cast-in-place concrete hollow floor were analyzed, and these issues were discussed combined with the norms. Programs in the current market used for calculation of cast-in-situ concrete hollow floor structure were summarized and compared. The present design situation of hollow floor was analyzed, and some misunderstandings of cast-in-situ hollow floor design were discussed. Finally, the prospects of cast-in-situ hollow floor development were introduced as well as the development direction combined with structural optimization and prestressed design.

Keywords:cast-in-situ concrete hollow floor; optimization; large span
