$1.$ Each group will hand in one project.

$2.$ Projects must be neatly presented in a folder. Write$/$ draw on one side of the page only.

$3.$ The cover page must include the course code, title of project, date, group number and list of group

members $($initials$,$ last name, and student number$).$

$4.$ Each calculation must have a corresponding neat sketch. All relevant dimensions, section sizes etc.

must be given, with a title on the drawing.

PROJECT BRIEF

Figure $1$ below shows the canopy at the entrance of Centenary Building.

The structure supports roof sheeting, and is supported by a system of steel beams at C and B$.$ These

loads are then transferred from the beams to the columns, to the foundations and into the ground. Tie

rods are attached to the wall at Point A and to the beam at Point B as shown in the idealised Sketch in

Figure $2.$

For the $6$ kN load at Joint B:

$1.$ Determine the member forces and normal stresses in members A$-$B and B$-$C$.$

$2.$ Calculate the deflection of the tie A$-$B$.$

$3.$ Determine the strain in the tie.

$4.$ Check if the strength of the tie is sufficient if it is made of Grade S$355$JR steel with Minimum Yield

Strength of $355$ MPa and Ultimate Strength of $480$ MPa.

$5.$ If the connections at points A$,$ B and C consist of a single bolt $($diameter $20$mm$),$ with $2$ plates on

either side, calculate the shear stress in the bolt at point A$.($refer to Figure $3$ for detail$)$
