Description

Objective This report aims to further understand the performance levels and failure mechanisms in the design of steel structures. This analysis is completed through the design, fabrication, and testing of a simple I-beam structure. The report will showcase the most optimal geometric design devised by the group and detail the fabrication method for the steel beam as well as the resultant testing of the steel beam. The project specifications provided for the design are: -

Cross Section is an I-beam Maximum length of beam 800 mm (+/- 5 mm) Maximum of 8 stiffener plates Maximum of 50 rivets

The materials provided for the design are: -

Two cold formed steel sheets of 800 mm x 150 mm x 0.79 mm One addition sheet for stiffeners Type C200 steel pop rivets (requires 4 mm diameter hole)

The report requires an optimal design for the beam considering geometric properties such as the flange thickness, flange width, web depth and web thickness. The calculations provided in this report include an analysis detailing: -

Nominal member capacity Load carrying capacity for the beam Deflection of the beam Compactness check Web shear capacity Web bearing capacity Minimum capacity

Through this report, students will be able to develop a better understanding of why structural elements are manufactured the way are. Additionally, fabrication of the beam in the lab provides a practical understanding in the development of components of steel structures.

Summary The fabrication for the design begins through marking the ideal dimensions for the beam and selecting an effective geometric configuration. The markings are then cut with the guillotine and the steel plate is bent to shape with a panbrake folder. Holes are then drilled with a power pedestal drill for the riveting process to begin. The fabricated steel beam finally undergoes a three-point bending test where the load is applied through a 50 mm wide steel plate at the centre of the beam. The...
