What is the minimum size of fillet weld for steel plate with thickness of 1 inch

Question

What is the minimum size of fillet weld for steel plate with thickness of 1 inch? In the formula for calculating the block shear strength of bolt connection, i.e., Eq 3.9.4 on the text book, it contains 0.6 F_y. What is physical of 0.6F_y? If bolt diameter is d_b = I", what is the typically used spacing between bolts in the bolt connection? For a plate subject to tension load, the design tension is T_ = l00 kips, it is found that the nominal tension capacity of the plate is T_n = 120 kips and the corresponding strength reduction factor for the tension failure mode phi = 0.75, to determine whether the plate can resist the load When designing a weld connection for two plates, what types of failure modes should you consider and exam (name all possible failure modes)? For the bolt connection shown below, to draw a possible failure mode of the block shear of plate A in the Fig below? For the bolt connection shown below, to draw a possible failure mode of the pure tension of the plate A in the Fig below?

Explanation / Answer

1) According to codic provisions , the minimum size of fillet weld for the steel plate of 1 inch is 6 millimeters

2) The direct stress in axial tension on the effective net area should not exceed 0.6fy

where fy = minimum yield stress of steel

3) Generally the spacing provide is 2.5 times the nominal diameter of the rivet , i e 2.5 x 1 inch = 2.5 inch

5) a) Shearing of bolts Failure

b) Tension Failure

c) Slip failure

d) Bearing failure of plate

e) Bearing failure of bolt

f) Combined shear and tension
