Q$2$

a$)$ A flat bar $12"$ wide by $\frac{3}{8}"$ thick, is to be used as a tension tie. The vertical edge distance from the center of the bolt holes is $2"$ and the center to center distance $($horizontally and vertically$)$ between adjacent bolt holes is $3".$ The bar is to be constructed from two lengths connected together with a lap splice using $8$ no$.\frac{3}{4}"$ bolts as shown in the figre below. Calculate the design tensile resistance of the bar assuming A$36$ plates are used.

b$)$ The steel beam on line $\text{'}$ C $\text{'}$ on the structural plan illustrated in Q $1$ is a W$14$x$26,$ and is made from A$992.$ Assuming the beam is simply supported and fully restrained against LTB$,$ assess the adequacy of the critically loaded beam section.

NB: $-$ checks should be performed for flexure, shear and deflection.

the self$-$weight of the beam should not be ignored.

NB: Comment on the results obtained from the design checks for parts $($a$)$ & $($b$).$
