QUESTION $2$: PLEASE DONT USE CHATGPT OR I WILL SIGNAL $.$

A simply supported beam $($L$=9$ m$)$ has been designed as a composite steelconcrete member. The beam is subjected to two factored concentrated loads $($Pf $=80$ kN$)$ as shown

in the figure. The $28-$day strength of the concrete is $20$ MPa and the steel is $300$W$.$ The provided

shear studs have a diameter of $22$ mm and ultimate tensile strength of $415$ MPa.

a$)$ Determine the minimum number of studs that are required in full interaction if the horizontal

shear force at the interface is $900$ kN$.$

b$)$ Show the distribution of the studs $($location and spacing$)$ according to CAN$-$CSA$-$S$16-2014$

requirements if the structural steel section has a factored moment resistance Mr$=120$ kN$.$m
