The new concrete ribbed beam hollow floor cover based on the two-way ribbed beam is suitable for projects with large loads or large spans on the upper part. This paper mainly introduces the characteristics and composition of concrete ribbed beam hollow floor, collates and analyzes the test data obtained from the static loading test of the floor, obtains the structural performance of the test piece, and obtains the vertical overall displacement of the floor. The vertical displacement of the mid-span and the development of the crack, the ultimate bearing capacity of the hollow slab with the rib beam is obtained through the failure test. Under the normal load, the new ribbed hollow floor has good integrity. It is concluded that the hollow ribbed hollow floor cover has the characteristics of large bearing capacity and good overall rigidity.
