[0026] In order to make the technical field personnel better understand the technical scheme of the present application, the technical scheme of the present application will be further described in combination with specific embodiments.
[0027] In combination Figures 1 to 5 As shown in the figure, the embodiment is a steel frame test specimen with a floor slab, which comprises a floor slab 6, a bottom support structure and a lateral support structure. The bottom support structure is arranged at the bottom of the floor slab 6 and is used to provide bottom support for the floor slab 6. The top of the bottom support structure is provided with the lateral support structure, which abuts the two side walls of the floor slab 6. The lateral support structure is used to provide lateral support for the floor slab 6, so that the two sides of the floor slab 6 form a constraint boundary.
[0028] In some embodiments, the bottom support structure comprises steel columns 1 and steel beams 2. The two ends of the steel beams 2 are respectively connected to the top of the side walls of the two steel columns 1. The top of the steel beams 2 and the steel columns 1 is provided with the lateral support structure and the floor slab 6.
[0029] Further, the floor slab 6 and the steel beam 2 are connected by a plurality of studs 5, which can effectively transmit shear force to a certain extent and enhance the integrity of the structure.
[0030] In some embodiments, the lateral support structure comprises support members 3 and support connecting members 4. The two sides of the steel beams 2 and the steel columns 1 are symmetrically arranged with the support members 3. A plurality of support members 3 are arranged at intervals along the length direction of the floor slab 6. The adjacent support members 3 are connected by the support connecting members 4, so that the support connecting members 4 are symmetrically arranged along the axis of the steel beam 2. Specifically, three pairs of support members 3 are arranged in the embodiment. The support members 3 are symmetrically arranged on the two sides of the two steel columns 1 and the two sides of the middle part of the steel beam 2. The support members 3 are parallel to each other. The ends of the three pairs of support members 3 are connected to the support connecting members 4.
[0031] Further, the support members 3 are made of I-beams or H-shaped steel. The support members 3 and the steel columns 1, and the support members 3 and the steel beams 2 are welded. The support connecting members 4 are made of angle steel.
