What is the minimum size of fillet weld for steel plate with thickness of 1/4 in

Question

What is the minimum size of fillet weld for steel plate with thickness of 1/4 inch? In the formula for calculating the block shear strength of bolt connection. i.e. Eq. 3.9.5 on the text book, it contains 0.6 F_. What is the physical meaning of 0.6 F_ ? If bolt diameter is d_b = 1^. what is the typically used spacing between bolts in the bolt connection? For a plate subject to tension load, the design tension is T_ = 100 kips, it is found that the nominal tension capacity of the plate is T_ = 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 Determine the design connection capacity or design strength phi Tn of the following bolt connection. The bolt used in connection is I -in. diameter A325-N bolt and total four bolts are used. All plate is G50 and dimension is 1/2^times 6^plate (Fy = 50 ksi and Fu = 65 ksi). You need to exam all possible failure modes (for example, bolt shear failure, plate bearing failure, plate tension failure, or plate shear block failure) and draw the failure path

Explanation / Answer

5) For plate thickness of 1/4 in , the minimum size of the fillet weld is 1/8 in.

7) As per AISC J3.3 sapcing not less than 2.67*dia and preferrably 3*dia.

Hence for 1 inch bolt, the spacing between the bolts is 3*1 = 3 inch.
