Design of Truss Structures Through Reuse

Corentin Jean Dominique Fivet, Gennaro Senatore, Jan Friedrich Georg Brütting, Joseph Jean François Desruelle

This paper presents structural optimization techniques to design truss structures that make best use of a given stock of structural components. Still little explored, the reuse of structural components over multiple service lives has the potential to signi ...

Strengthening of metallic members under mixed mode fatigue loading using prestressed CFRP plates

Ardalan Hosseini

The strengthening of existing steel structures against high-cycle fatigue (HCF) loading has become one of the most important topics of interest in structural rehabilitation. Apart from the conventional strengthening techniques that incorporate bulky and he ...

The role of thermal loads in the performance-based design of energy piles

Lyesse Laloui, Aurelio Muttoni, Alessandro Francesco Rotta Loria, Cristiano Garbellini, Matteo Bocco

Over the past two decades, a substantial amount of research has investigated the effects of thermal loads associated with the geothermal operation of energy piles on their mechanical response. Based on this research, consensus about the need for considerin ...

Adding value to bridges by monitoring and UHPFRC technology

Eugen Brühwiler

Novel structural engineering methods and technologies are urgently needed to improve the performance of existing structures, such as bridges. Limited funding and ever increasing user demands challenge current technologies which are often invasive and not c ...

Stress mitigation for adhesively bonded photovoltaics with fibre reinforced polymer composites in load carrying applications

Thomas Keller, Yu Bai

Structural loads, especially in-plane compression, may cause local buckling and debonding of the photovoltaic (PV) cells that are mechanically integrated with structural members and this may lead to degradation in their electrical performance. This paper p ...

Static behavior of Reinforced UHPFRC beams with thin cover depth

Eugen Brühwiler, Bartlomiej Wojciech Sawicki

Because of its high tensile strength and deformation capacity, UHPFRC (Ultra High Performance Fiber Reinforced Cementitious composite) can theoretically be used without any reinforcement bars or prestressing. However, for more economical design and for rea ...

Damage mitigation of a near-full-scale deployable tensegrity structure through behavior biomimetics

Ian Smith, Ann Christine Sychterz

Current infrastructure is designed and built such that it must simultaneously comply with all possible loads. This leads to overdesigned structures that are inefficient in terms energy and cost. A structure that can self-identify damage, adapt, and learn f ...

Computational tools for the fatigue life modeling and prediction of composite materials and structures

Anastasios Vassilopoulos

Structural testing is probably the best and only way to reveal the actual performance of composite laminates, structural components, and complete composite structures under fatigue loading. Nevertheless, the high cost, and the multitude of loading cases a ...

Energy geostructures: anew era for geotechnical engineering practice.

Lyesse Laloui, Melis Sütman

Energy geostructuresprovide low carbon, cost-effective and local energy solutions to structures and infrastructures, which opens a new era for the geotechnical engineering practice, by extending the conventional role of geotechnicaldesign to the one of add ...

Performance Assessment of Double-Layered Timber Plate Shells using Alternative Structural Systems

Yves Weinand, Petras Vestartas, Anh Chi Nguyen, Bertrand Mathieu C Himmer

With recent advances in digital fabrication, innovative wood-wood connections inspired by ancient timber joining techniques have recently been applied to various free-form timber plate structures [1]. This paper focuses on the recently developed double-lay ...
