@@martindsouza2659 I calculated using 35. I agree with you. In case of block shear failure, the tension failure should happen along the line from bolt to the outer edge of angle and that was 35mm.

In the block shear calculation for welded connection thickness of angle used; not the thickness of gusset plate as in the case of earlier weld problem🤔
@shivamsharanlall6724 жыл бұрын
Actually your thought is correct but the thing is that the thickness of the plate is not given in the question, so the thickness of the plate is considered equal to that of the angle.

Isn't that we need to take the longer weld length running along the toe of the angle in the calculation of the Avg and Avn in the block shear?
@shivamsharanlall6724 жыл бұрын
Avg = Avn = 2* 164.3 * 10 = 3286 mm^2 Lw1 = 164.3 mm instead of 165 mm i.e average weld length.

@shivamsharanlall6724 жыл бұрын
@@snehasneha8270 actually when you see the block shear failure in weld connection, you consider that the whole gusset plate which is connected by the angle through weld is torn out due to this failure. So the tensile force is acting along the plane of the gusset plate which is not even welded up.
@shivamsharanlall6724 жыл бұрын
You can go though a similar problem in Lecture notes---design of steel structures----Uma Shankar Yaligar---pg 110,eg 4. Although here the welding is done in the tension area of the gusset plate and angle.
