Question

01.A 12 mm bracket plate is connected to a column flange as shown in the figure below. The bracket transmits a load of W 200 kN to the column flange. A 10 mm fillet weld is provided along AB, BC and CD. If e 350 mm, b 200 mm and d 600 mm, Verify if the size of the weld provided is adequate. Allowable shearing stress in the fillet weld can be taken to be 108 MPa.

plz sure .don't attempt if u r not sure.negative rates for wrong answer

Answer 1

plz rate

Throat of filled weld t = 0.7 times 5 = 0.7 times 10 = 7 mm let co of weld be at x vector from left edge an thrown x vector = (600 times 0) + (2 times 200 times 100)/600 + 200 + 200 = 40 mm for fillet weld, Irx Irx = 7 times 600^3/12 + 2 times [200 times 7^3/12 + (200 times 7) times 300^2] Irx = 375 times 10^6 mmY Iyy = 2 [7 times 200^3/12 + 200 times 7 times (100 - 100)^2 + [600 times 763/12] + 600 times 7 times 40^2 = 26.15 times 10^6 mmY Ir = Irr + Iyy = 404.15 times 10^6 mmY Ps = 200 times 10^3/(600 + 2 times 200)x 7 = 28.57 N/mm^2 Pr = squareroot Ps^2 + Pb^2 + 2Ps Pb Cos theta Pr = squareroot (28.57)^2 + (85.8)^2 + (2 times 28.57 times 85.8
