(2) The wind area:
the demolition area is 3 × 3.5m, and the demolition range is 3 × 4.0 m-12 m2 in consideration of the related error in the demolition process.
(3) And (3) correlation calculation:
the whole wind pressure is applied 3.5 × 12 to 42kN, and is received by the two-side structural columns, so that the force applied to each side is 21 kN. Through correlation calculation, the maximum shearing force borne by the column is about 19.7kN, 20kN is taken, and the maximum bending moment borne by the column is about 6.8kN.m, 7kN.m is taken.
Checking and calculating a constructional column:
the shear member was examined as follows using a 200X 200mm construction column as the moment resistance:
the column can meet the shearing resistance under the condition of no reinforcing bars, so the shearing resistance of the constructional column is met.
Rectangular section normal section flexural bearing capacity
The column can meet the bending resistance under the condition of reinforcing bars of 115mm2, 4 reinforcing bars with the diameter of 12 are arranged on the constructional column, the area of a single-side reinforcing bar is 226-115, and therefore the constructional bending resistance is met.
③ local stabilization:
and the single side is connected by 8M 12 through pull bolts, so that 20/8 is 2.5kN, the strength of the M12 bolt is 26.1 to 2.5kN, and the requirement is met.
Fourthly, calculating the steel plate:
after 2 vertical steel beams are arranged, the plate is a one-way plate, the maximum bending moment is 0.63kN.m, and the thickness of the steel plate is 3 mm. The above values are therefore checked for intensity.
Maximum positive stress sigma 214.385(N/mm2)
Average shear stress τ 0.000(N/mm2)
Maximum value of shear stress under Fx τ max:0.000(N/mm2)
Maximum value of shear stress under Fy τ max:0.000(N/mm2)
Note that: the program calculates the maximum shear stress value without considering the synthetic shear force
214.4| ≦ f 215.0(N/mm2) | f/σ |, 1.003 satisfies
Fv 125.0(N/mm2) | fv/τ |, 99999.000 satisfies | τ | 0.0| ≦ fv | 125.0 |
Through the calculation, the protective device meets the requirement of the bearing capacity attached to the wall body, and the device meets the requirement of wind pressure resistance.
