作业范例（Homework paradigm） Steel - concrete composite flat girder integral building bearing performance Test report Single: Graduate students: Lead teacher: Vice supervisor: Time: Test floor design calculation 1. Purpose of test As a new type of building form, the composite flat beams have been widely used in Europe, especially in northern Europe. However, due to its short time, relevant research results are limited. In addition, because the structure form in Europe, the past relevant studies are mostly limited in terms of vertical bearing performance and fireproof performance, but our country is in an earthquake-prone countries, still need to adopt the new floor form in our country to this floor levels in the form of bearing performance and seismic performance for further study. The purpose of this experiment is as follows: 1. The overall performance of the buildings self-vibration frequency and space (without floor load and normal use of floor load); 2. The stiffness and deformation under the vertical load bearing of the whole floor, the stress distribution of the floor slab (the beam of the middle and the side of the two sides and the rib); Deformation under horizontal load, stress distribution and hysteresis performance; Based on the experimental results, the effective width of composite flat beam and the frame model for designing the calculation are put forward. Two. Research object The object of this study is the whole building cover of the steel - concrete deep rib composite flat beam, which has two spans, the total plane size is 6m x 12m, and the height of the floor is 3 meters, and the foot ruler is designed, as shown in fig.1. FIG. 1 overall layout of the study subjects In the building span, a secondary beam is set, the main beam and the column are just connected, the secondary beam is connected with the main beam, the bottom structure is shown in figure 2, the concrete rib is arranged in the direction perpendicular to the secondary beam. Figure 2 shows the b
