$*$SHOW THE SOLUTION$*$

Situation $2$: A W$360$X$79$ of A$992$ steel is

connected through its flanges with M$22$ bolts as

shown. The material strengths are $F_y=$

$345$MPa and $F_u=483$MPa. Use $s_1=$

$50\mathrm{.}8mm,s_2=76\mathrm{.}2mm.$

Properties of W$360$X$79$:

$A=10100m{m}^2,d=353mm,b_f=205mm$

$t_f=16\mathrm{.}8,t_w=9\mathrm{.}40mm$

Properties of WT$180$X$39\mathrm{.}5$

$A=5030m{m}^2,d=177mm\frac{,}{b}ar(y)=35\mathrm{.}1mm$

Which of the following most nearly gives the

nominal strength of the tension member

based on tensile yielding?

a$.3844kN$

c$.3448kN$

b$.3484kN$

d$.4348kN$

Which of the following most nearly gives the

shear lag factor?

a$.0\mathrm{.}846$

c$.0\mathrm{.}850$

b$.0\mathrm{.}864$

d$.0\mathrm{.}900$

Which of the following most nearly gives the

net area of the tension member?

a$.8352m{m}^2$

c$.6605m{m}^2$

b$.9226m{m}^2$

d$.8487m{m}^2$
