Fire performance evaluation of GFRP-balsa sandwich bridge decks
Bridges are a critical component of national infrastructures and economies. A significant percentage of bridges built all around the world are made of reinforced concrete which according to building codes have a life span between 80-100 years. However, str ...
EPFL2022Mechanical properties of a balsa wood veneer structural sandwich core material
Thomas Keller, Anastasios Vassilopoulos, Niloufar Vahedi
Balsa wood is an appropriate core material for structural sandwich applications due to its high strength- and stiffness-to-weight ratios. However, the mechanical properties vary considerably owing to the inherent scattering of natural wood materials. One a ...
2020Thermomechanical characterization of a balsa-wood-veneer structural sandwich core material at elevated temperatures
Thomas Keller, Anastasios Vassilopoulos, Chao Wu, Niloufar Vahedi
The tensile, compressive and shear behavior of standardized specimens cut from a veneered balsa wood used as structural sandwich core was investigated at ambient temperatures of up to 250 degrees C. The average moisture content was 9.1%. The specimens' res ...
ELSEVIER SCI LTD2020Double-layered timber plate shell. International Journal of Space Structures
Yves Weinand, Mark Pauly, Christopher Werner Matthias Robeller, Mina Konakovic Lukovic, Mira Dedijer
This article presents a new lightweight construction system for doubly curved shells made from timber plates, inspired by the masonry vaults of Eladio Dieste. The system was developed for a specific case-study project, and general applications to other fre ...
2017Structural performance of complex core systems for FRP-balsa composite sandwich bridge decks
Based on current fiber-reinforced polymer (FRP) composite construction principles, FRP decks fall into two categories: pultruded decks and sandwich decks. Sandwich decks comprise face sheets and either honeycombs or foams reinforced with internal FRP webs ...
EPFL2014FRP-balsa composite sandwich bridge deck with complex core configuration
Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Michael Osei-Antwi
The aim of this work was to investigate to what extent the performance of a glass fiberreinforced polymer (GFRP) sandwich slab-bridge with uniform high-density balsa core could be improved in terms of structural efficiency and weight thanks to a more compl ...
2014FRP-Balsa Composite Sandwich Bridge Deck with Complex Core Assembly
Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Michael Osei-Antwi
The aim of this work was to investigate to what extent the performance of a glass fiber-reinforced polymer (GFRP) sandwich slab-bridge with a uniform high-density balsa core could be improved in terms of structural efficiency and weight by using a more com ...
