Reuse in Architecture & Structural Design

Jan Friedrich Georg Brütting

Introduction The construction industry has an extensive impact on the global environment and will be facing three big challenges in the next decades: reducing its resource consumption, decreasing its energy use, and limiting its waste production. This is e ...

“STRUCTURAL UHPFRC” TO ENHANCE BRIDGES

Eugen Brühwiler

“Structural UHPFRC” stands for Ultra-High Performance Fiber Reinforced Cementitious Composite material that is complemented by reinforcing and prestressing steel to enhance the resistance and durability of structural elements. Properties of impermeable, te ...

Long-term design of FRP-PUR web-core sandwich structures in building construction

Thomas Keller, Julia De Castro San Roman Fest, Sonia Yanes Armas

The structural behavior of GFRP-polyurethane (PUR) web-core sandwich structures subjected to sustained loading was investigated. As a basis, a study of the mechanical behavior of rigid PUR foams used as core materials was conducted, with emphasis on creep. ...

Integrally attached timber folded surface structures

Andrea Stitic

In structural engineering, folded surface structures present one of the concepts for construction of self supporting column free systems. They utilize structural benefits of folding to achieve material saving and improve structural efficiency. The folding ...

Towards biomimetic behavior of an active deployable tensegrity structure

Nicolas Willy Veuve

Tensegrity structures have non-conventional structural properties since they require self-stress in order to be stable. When a tensegrity structure integrates sensors, actuators, (structural members able to change their length) and a control system, deploy ...

A fully geometric approach for interactive constraint-based structural equilibrium design

Corentin Jean Dominique Fivet

This paper introduces computational techniques to support architects and structural designers in the shaping of strut-and-tie networks in static equilibrium. Taking full advantage of geometry, these techniques build on the reciprocal diagrams of graphic st ...

Funicular Explorations: Cardboard Box Curves Achieved through External Post-Tensioning

Corentin Jean Dominique Fivet, Catherine Elvire L. De Wolf

Structural designers often face the challenge of developing forms optimal for a broad range of requirements, but inefficient in terms of structural behavior. In these cases, bending moments often occur under normal loading, resulting in oversized, inelegan ...

Amélioration de la fiabilité des évaluations environnementales des bâtiments

Endrit Hoxha

This PhD thesis focuses on improving reliability of the LCA of buildings by a better control of the origin and magnitude of uncertainties. It contributes to: - The development of a methodology for assessing uncertainty in LCA of buildings; - The constructi ...
