Problems solved by technology

If the binding force provided by the cast-in-place concrete floor slab is strong and no obvious damage occurs, it will generate a large binding force on the frame and destroy the self-centering ability of the beam-column joints of the self-centering prestressed frame, thereby affecting the overall structure seismic performance

Embodiment Construction

[0015] The technical scheme of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] Such as Figures 1 to 6 As shown, a self-centering prestressed concrete frame floor structure of the present invention, the concrete frame floor structure includes N horizontally arranged spans 1, N is an integer greater than 1, for example, N can be 2, 3 or 4. exist figure 2 Among them, N is 2. Each span 1 includes four main beams 2, M secondary beams 3, where M is an integer greater than 1, four frame columns 4 and a floor 5. The main beam 2 is connected between two adjacent frame columns 4 through prestressed steel strands, and the main beam 2 and the frame columns 4 form a rectangular frame. The secondary beams 3 are connected between two opposite main beams 2 . The floor 5 is located above the main beam 2 and the secondary beam 3 . In one span 1, the number of secondary beams 3 is determined according to the actual ne...

Abstract

The invention discloses a self-centering pre-stressed concrete framework floor slab structure, which comprises spans with the quantity of N which are horizontally arranged, wherein each span comprises four main beams, secondary beams with the quantity of M, four framework columns and floor slabs, wherein the main beams are arranged between two adjacent framework columns through a pre-stressed steel stranded wire, each secondary beam is arranged between two opposite main beams, and the floor slab is arranged above the main beams and the secondary beams; every two adjacent spans share one main beam and two framework columns, in one of the spans, the secondary beams and the two main beams which are connected with the secondary beams are respectively and fixedly connected with the floor slab through a tightening device, and the rest two main beams are connected with the floor slab through a sliding device; and in each span of the rest spans, the main beams and the secondary beams are respectively connected with the floor slab through the sliding device. Under the action of single-direction earthquake, due to the adoption of the concrete framework floor slab structure, the damage to the self-centering pre-stressed concrete framework caused by the restriction effect of the floor slab can be reduced.

Description

technical field [0001] The invention relates to a frame floor structure, in particular to a self-centering prestressed concrete frame floor structure. Background technique [0002] The traditional cast-in-place concrete frame slab structure is to connect the slab and beams in-situ. Specifically, the self-centering prestressed concrete frame includes N horizontally arranged spans, where N is an integer greater than 1, and each span includes four main beams and M secondary beams in a rectangular arrangement, and M is an integer greater than 1 , four frame columns and floor slabs, the main beam is connected between two adjacent frame columns through prestressed steel strands, the secondary beam is connected between the two opposite main beams, and the floor is located above the main beam and the secondary beam . Adjacent spans share a main beam and two frame columns. For the self-centering concrete frame, if the cast-in-place concrete floor structure is adopted, the fixed co...
