Analysis of the Design-Acquire Paradox inherent in the Reuse of Structural Steel Elements using an Ambidextrous Management Approach

Recently, the construction industry has been confronted with changing regulations, especially with the advent of sustainability goals and circular economy ambitions. The Dutch government wants to accomplish its ambitious initial objective of using 50% fewer primary resources by 2030. Further, by 2050, the goal is to have a waste-free economy...

Probabilistic strain-fatigue life performance based on stochastic analysis of structural and WAAM-stainless steels

Wire arc additive manufacturing (WAAM) has increasingly attracted attention in the construction sector because of its ability to produce large metallic structural parts in short times. In this paper, Coffin-Manson and Morrow (CMM) equation is employed to compare the fatigue life of WAAM stainless steel with the structural steels S355 and S690...

Quantifying Life Cycle Environmental Benefits of Circular Steel Building Designs: development of an environmental assessment tool for reuse of steel members in building designs for the Netherlands

The re-use of building components and structural elements is an underdeveloped practice which could be an important strategy in the global paradigm shift towards a circular economy. Steel is one of the most important structural building materials which combines incredible strength, favourable mechanical properties and excellent durability...

Successful steel reuse in the UK – key aspects why it happened

With growing pressure on the construction industry to be more resource efficient, to reduce waste and to lower embodied carbon, material reuse strategies are critical to meet targets, especially for steel. Indeed, steel recycling is an energy and carbon intensive process, offering only approximately 50% energy savings [1] and 75% [2, 3] over new...

Numerical Research on Elasto-Plastic Response of FPSO Topside Modules Subjected to Blast Loading Aiming at a Simplified Design Method

Structural blast analysis is usually done with two load levels for different design stages; the Strength Level Blast, SLB, and the Ductility Level Blast, DLB. Strength Level Blast is the lower magnitude overpressure (with a higher frequency of occurrence and lower consequence) and Ductility Level Blast is the higher magnitude overpressure (with...
