Mechanical Characterisation of Multi-Wythe Masonry Bridge in the City of Amsterdam

This paper presents the results of an experimental campaign carried out to characterise the mechanical properties of multi-wythe masonry infrastructure in the city of Amsterdam. Samples were extracted from a 1.2 m thick bridge’s pillar constructed in 1882. For the characterisation of shear and compressive properties of masonry, tests on cores...

Structural Assessment of a Masonry Quay Wall in Amsterdam Under Traffic Loading

Canals delimited by masonry quay walls are integral elements of many cities in the Netherlands. Historically built to enable the efficient transportation of goods, today such infrastructure also gives the cities their historical and monumental character. In recent years, many quay walls in the Netherlands have shown substantial deformation and...

Innovative Application of Self-healing Technology to Masonry: A Proof of Concept

Cracks are one of the most common expressions of damage in masonry structures. Aside from aesthetic issues, they can compromise the overall behaviour of the structure; therefore, they are undesirable and need to be repaired. The repointing technique is traditionally implemented in this context, especially in historical masonry. Nevertheless,...

Structural Design and Testing of Digitally Manufactured Concrete Structures

The form freedom enabled by digital fabrication with concrete technologies provides advantages for a wide range of concrete based objects, from architectural to structural elements. The current chapter focuses on the specifics of structural design and engineering of DFC with emphasis on those technologies based on Additive Manufacturing with...

Numerical Modelling Of Two-Way Out-Of-Plane Bending Tests On URM Walls: The Influence Of Lateral Boundary Conditions

Research has shown that lateral boundary conditions can have a large influence on the force capacity of two-way spanning unreinforced masonry (URM) walls subjected to out-of-plane (OOP) loading. Differently than laterally free one-way spanning walls, they show a higher force capacity, which however is underestimated by current analytical...

Measuring and modelling the deteriorating impact of Alkali-Silica Reaction in concrete on the mechanical characteristics

Unaffected and ASR-affected concrete, experimentally, appear as substantially different materials. Since the material characterization is one of the main points of attention within a structural assessment, the deteriorating impact of ASR on concrete in terms of both expansion and degradation of the mechanical properties is studied. Both...
