Project: Design of Industrial Shed Trusses for Casuarina Campus

As a junior engineer, you are tasked with designing the trusses for an industrial shed to be

constructed at Casuarina campus, Charles Darwin University. Utilize the approximate method

covered in week $2$ of the lectures to complete the design. Below are the revised specifications:

Shed Dimensions:

Width: $32$ meters $($span of the truss$)$

Length: $62$ meters

Spacing between trusses: $3\mathrm{.}5$ meters

Eave Height: $9$ meters

Truss height to be determined based on your design

Loads:

Roof dead load $($excluding truss self$-$weight$)$: $2\mathrm{.}5k\frac{N}{m}$

Roof live load as per AS$1170$ standards

Maximum permissible axial stress in the truss: $210$ MPa

Maximum allo wable deflection under imposed load: span$/360$

Material and Cost:

Young's Modulus for steel: $210{10}^2$MPa

Estimated cost for erected steelwork: A$$9500$ per tonne

Project Requirements:

Design Proposals:

Develop two distinct design scenarios using Circular Hollow Sections $($CHS$).$ Ensure all calculations

are presented clearly.

Comparison and Discussion:

Evaluate both design scenarios from structural and economic perspectives. Discuss the reasons for

any differences observed.

Submission Guidelines:

Include a detailed report with calculations, design sketches, and justifications for your design

choices.

The project is to be completed individually.
