Master’s thesis proposal: Crane girder design, investigation of HFMI applications

Job Description

Background

• Crane runway girders are vital components in industrial structures, ensuring smooth crane operations. Failure in these components can halt production, causing significant financial losses and safety risks. Although they might seem simple at first glance—just a steel beam spanning over multiple supports—their design and performance are crucial.
• Optimizing crane girder design, particularly for heavier cranes, is essential for reducing costs and carbon emissions and ensuring durability. This includes using thinner web plates and optimizing welds for fatigue. HFMI can be used to optimize some of the details which could lead to smaller weld and hence, smaller plates and more durable design.

Aim

• Comparison of current version of Eurocodes, new version of Eurocodes and American codes for crane girders with regard to fatigue design
• Investigation of using HFMI for different details

Method

• Review requirements regarding crane girders, fatigue (Eurocode, AISC, etc)
• Investigation of HFMI on different details

What you gain

• By the end of this project, you will have gained a comprehensive understanding of various aspects of design and optimization of crane runway girders, including relevant standards, fatigue design, and structural stability. This knowledge is essential for future roles as structural engineers, particularly in the field of industrial structures, where ensuring stability and efficiency is critical. 

Qualifications

• Good knowledge about steel structures and Eurocode 3
• Merit to have Experience with FE software (ex ABAQUS, Ansys, SAP2000 or other commercial software)
