Project Objective:

• An alternative “Direct Reuse Circular Economy Approach” is being investigated.

• The concept of Reuse of Steel Structural Members is being investigated by repeated testing to determine the safety factor. 

• It technically emphasizes how steel structures can be a solution to circularity and reuse concepts.

• A new strategy for integrating the features of the construction to create a circular economy is proposed.

Existing Design Specifications:

• ISO 20887 (2020) Sustainability in buildings and civil engineering works - Design for disassembly and adaptability - Principles, requirements and guidance. 

• PROGRESS (2020) Provisions for Greater Reuse of Steel Structures - European Recommendations for Reuse of Steel Products in Single-Storey Buildings ECCS – European Convention for Constructional Steelwork. 

Parameters considered:

• Where to begin the Circular Economy for Sustainability?

• How to integrate the various design and construction features for the direct reuse of structural members?

• How many times the structural member can be reused?

• What is the stress limit that the structural member should be loaded at first use, second use (reuse cycle 1), and so on? 

• Is there a relation between the stress level in the structural members and a number of reuse cycles? 

Nature of the work:

Development of Interlocking Connections for enabling Reuse | Development of Design Methods for Reuse like DfDR | Full-scale experiments | Numerical (Finite element analysis) |
