The fatigue safety of the reinforced concrete deck slab of a sixty-year-old steel-concrete road viaduct as well as the riveted steel girders of a 130 year old railway bridge was questioned based on the results of conventional assessment consisting in "re-c ...
In this paper, a mechanical model consistent with the main assumptions of the Critical Shear Crack Theory (CSCT) is proposed for shear design of slender concrete members without shear reinforcement. To that aim, the shear force that can be transferred thro ...

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 ...
Stiffened extended shear tab connections (either in full-depth or partial-depth configurations) are widely used to connect simply supported beams to the web of supporting girders or columns. Full-scale laboratory tests of stiffened extended shear tab conne ...
As fatigue cracks were discovered under the bridge deck of the 48 years old railway bridge Linthkanal-Brücke, located near the Ziegelbrücke town in Switzerland, a few studies were conducted to understand the mechanism behind the cracks formation. However, ...
Graphic statics provide a visual understanding of the relation between a structures’ shape and its efforts, a valuable quality in the field of structural conception. When combined to a shape grammar, the graphical method has proven to be a very powerful to ...
Much of the post-war reinforced and prestressed concrete infrastructure in North America and Europe is reaching its design life and engineers are in need of tools that can be used to assess the shear behavior of these structures. The Compression Field Theo ...
The region of Basel is considered one of the most seismically vulnerable in Switzerland: in 1356, a very damaging earthquake hit the city, which nowadays is characterized by a significant concentration of population and economic activities. Hence, the Cant ...
The science of adhesives and adhesion for structural connections has undergone significant development during the last few decades - and successfully so in a wide variety of industries. Recent applications of structural bonding are being adopted in the con ...

Construction of multi-storey reinforced concrete (RC) wall buildings in areas of moderate to high seismicity has become a common practice in several Latin-American countries such as Colombia, Peru, Ecuador and Mexico. The large material cost has led to the ...
