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. ...
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 ...
Looking back at the history of concrete houses around 1900, we can discover how reinforced concrete, initially tied to construction systems of renowned inventors (and other less known), is gradually becoming autonomous and a material on its own, highlighte ...
The Laboratory of Construction Materials in Lausanne has been studying the alkali-silica reaction for more than 10 years, advancing the understanding of the reaction, and also producing microstructural models which can be used to predict quantitatively the ...
This paper explores the geometric optimization of a planar reciprocal frame (RF) floor framing structure, focusing on the triangular topology. The structural performance of the frames is computed and plotted against the geometric parameters for various loa ...
Wood is usually perceived as a "traditional" material. However, the properties of this material have now for some time made it possible to design free shapes and highly complex structures. Today, the wood laboratory of the EPF Lausanne, which was originall ...
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 ...
Timber folded plate Structures combine the advantages of timber as a construction material, such as its carbon-dioxide storage, low energy production and favorable weight-to-strength ratio, with the structural efficiency and elegance of folded surface stru ...
The Swisswoodhouse concept is the outcome of a number of studies on issues related to urban densification, structural changes in households, housing adaptability and the environmental challenges of sustainable construction. The building design is more spec ...
This work presents the concept and structural design of a 1000-m2 glass fiber-reinforced polymer (GFRP) sandwich roof replacing a timber roof over an indoor swimming pool. The advantages offered by the lightweight, multifunctional GFRP-polyurethane (PUR) s ...
