List of top Design of Steel Structures Questions on Welded Connections asked in GATE CE

Consider the fillet-welded lap joint shown in the figure (not to scale). The length of the weld shown is the effective length. The welded surfaces meet at right angle. The weld size is 8 mm, and the permissible stress in the weld is 120 MPa. What is the safe load $P$ (in kN, rounded off to one decimal place) that can be transmitted by this welded joint? 

Two plates are connected by fillet welds of size $10$ mm and subjected to tension $P=275$ kN (factored). Plate thickness $=12$ mm. Steel: $f_y=250$ MPa, $f_u=410$ MPa. Workshop welding with partial safety factor. As per IS 800:2007 (Limit State), what is the minimum length (in mm, rounded off to the nearest higher multiple of $5$ mm) required of each weld to transmit $P$?}
