Calculation force of slab

1. Let's invite professional personnel. If you break it, you have to repair it

4. The calculated span is the direction of internal force you want. Because of its bi-directional bending property, both the long side and the short side have calculation length.

5. At least 150 tons

6. One end does not support the support that is buried or collapsed in the support and expanded
warming, and the other end is the two ends of the cantilever beam
not directly supporting each side (column, solid wall)
part of the structure is buried on the floor or outside the cast-in-place extension of the building structure
is another part of the cantilevered cantilever slab (such as cantilevered terrace, roof).

7. Yes, in addition to the constraints, it is also related to the size of the plate

8. It should be able to arrange the unfavorable load as a continuous beam. It should be calculated as a 4-span continuous beam by checking the coefficient. If not, the single one-way slab should be calculated as a simply supported beam, and the fixed end of the span should be calculated as the support

9. 1. Decompose f into horizontal and vertical components, and take moment at o point respectively
2. Ya = 20 / 3 (up), YC = 10 / 3 (up); Calculation by section method: M11 = 40 / 3kn. M (under tension), fq11 = 20 / 3kn; M22 = 40 / 3kn. M (under tension), fq22 = - 10 / 3kn
