Les Cahiers de l'Ibois 3 / Ibois Notebook 3

Before the twentieth century and concrete modernity, it was stone that embodied the “well built”. Could sustainable wood one day replace concrete as the archetypal material? Will it find a place on the scale of values that gives archi- tecture its referenc ...

Steel Sheet Sheathed Cold-Formed Steel Framed In-line Wall Systems. I: Impact of Structural Detailing

Fani Derveni

The North American construction industry has seen substantial growth in the use of cold-formed steel (CFS) framing for midrise buildings in recent years. In seismic zones, CFS-framed buildings utilize shear walls to provide the primary lateral resistance t ...

Design and temporal issues in Soil Bioengineering structures for the stabilisation of shallow soil movements

Giovanni De Cesare, Massimiliano Schwarz

In the last decades, soil bioengineering has gained considerable popularity worldwide, especially in hillslope, riverbank, and earth embankment stabilisation works. The use of plants as a building material transfers the plant multifunctionality within engi ...

Component reuse in structural design: emerging practices and tools for the circular economy

Corentin Jean Dominique Fivet, Jonas Warmuth, Pierluigi D'Acunto, Jan Friedrich Georg Brütting

Structural engineers play an increasing role in ensuring the transition towards a more sustainable construction sector: a) they are responsible for the design of the most resource- and energy-intensive part of buildings and infrastructure, and b) they regu ...

Remarkable Color Gamut Enhancement of Dye Lacquers Using Corrugated Surfaces

Olivier Martin, Sebastian Mader

The visual appearance of any colorized object is usually determined by the spectral absorption of either pigments or dyes. One can however also colorize objects with structural colors that typically have an iridescent appearance, as seen on many beetles. T ...

A new method to design structures that adapt to loads via large shape changes

Ian Smith, Gennaro Senatore, Arka Prabhata Reksowardojo

The construction industry contributes to more than a third of the global energy demand and consumes almost half of all mined material resources. It is thus important to include energy and material efficiency criteria for the design of civil structures. Ada ...

Recent development in the multiphysical analysis and design of energy piles

Lyesse Laloui, Alessandro Francesco Rotta Loria

This study proposes an analysis of the multiphysical phenomena governing the thermo-mechanical behaviour of energy piles. The analysis is based on the results of a series of full-scale in-situ tests, laboratory experiments and numerical analyses. First, th ...

Creep of Sandwich Panels with Longitudinal Reinforcement Ribs for Civil Engineering Applications: Experiments and Composite Creep Modeling

Thomas Keller, Mário Alexandre De Jesus Garrido

Composite sandwich panels with reinforcement ribs or webs are being increasingly considered for structural applications in civil engineering. Such panels are prone to creep when subjected to significant permanent loads and therefore the effects of this phe ...

Gusset Plate Connections for Naturally Buckling Braces

Hiroyuki Inamasu

A naturally buckling brace (NBB) is a steel brace that consists of a high-strength and low-yielding steel channel arranged in parallel with eccentricity acting along the brace length. To enhance the feasibility of NBB fabrication, three connecting design d ...

A review of the fire behaviour of pultruded GFRP structural profiles for civil engineering applications

Thomas Keller, Yu Bai

Pultruded glass fibre reinforced polymer (GFRP) profiles are finding increasing applications in civil engineering structures, owing to the several advantages they offer over traditional materials. However, due to the combustible nature of their polymer mat ...

Structural identification methods for full-scale bridges

Ian Smith, James-Alexandre Goulet, Irwanda Laory

Results of two doctoral theses, one using a model-based approach and the other using model-free methods, are summarized. Both included case studies of full-scale bridges. While model-based approaches are appropriate for individual infrastructure-management ...

Advanced Numerical Modeling of Cracked Tubular K Joints: BEM and FEM Comparison

Alain Nussbaumer, Luís Costa Borges

A critical aspect in the design of tubular bridges is the fatigue performance of the structural joints. The estimation of a fatigue crack life using the linear elastic fracture mechanics (LEFM) theory involves the calculation of stress intensity factors (S ...

Performance of two model-free data interpretation methods for continuous monitoring of structures under environmental variations

Ian Smith, Ngoc Thanh Trinh, Irwanda Laory

Interpreting measurement data from continuous monitoring of civil structures for structural health monitoring (SHM) is a challenging task. This task is even more difficult when measurement data are influenced by environmental variations, such as temperatur ...

Construction en pierre massive en Suisse

Stefano Zerbi

«For me, to build an air terminal with stone would be a stupidity, not to say a madness. But to use dynamic structures to fit three-roomed flats with kitchen in buildings from three to ten floors, is not less aberrant.»1 Provocation of a reactionary archit ...

Fire performance of water-cooled GFRP columns. Part I: Fire endurance investigation

Thomas Keller, Yu Bai, Christian Ludwig

Structural fire endurance experiments were conducted on full-scale cellular glass fiber-reinforced (GFRP) columns under axial compression and subjected to ISO834 fire exposure from one side. Unprotected columns can resist fire for more than 30 min, which i ...
