For the double$-$shear butt joint shown,

all the plates are made of ASTM A$36$

steel, the plate size is of $t=19mm$

thick, $b=150mm$ wide, the splice plate

size is of $t=11mm$ thick, $b=150mm$

wide, the $(8)$ high$-$strength bolts are of

$d=25mm$ diameter $A325N$ bolts.

Calculate

the load that the joint can support to resist shear failure, $P_s[kN]$

the load that the joint can support to resist bearing failure, $P_P[kN]$

the load that the joint can support to resist gross tensile failure, $P_G[kN]$

the load that the joint can support to resist net tensile failure, $P_N[kN]$

the joint efficiency, $[\%]$
