| Abstract: | A new style of prestressed concrete hollow floor and its economic indexes are introduced. The structure system of the floor is a prestressed beam system with I-sections, which can span large space, the ratio of the hollow core has reached 70% , and the economic span has reached 24m. The floor has advantage of clear mechanics, smooth surfaces, lower cost, simple design method and easy construction, so it is an ideal style of large span floor system. |

| Keywords: | prestressed concrete hollow floor I-section |
