Reuse of concrete elements in architecture: characterisations and design methods for sustainable structures

Because of established demolition routines and low construction-material production costs that neglect negative externalities, discarded concrete today is crushed and landfilled or downcycled as infill material or recycled aggregates, wasting its embodied ...

Experimental investigation of dowel action in reinforcing bars using refined measurements

Aurelio Muttoni, Marko Pejatovic

In typical reinforced concrete design, reinforcement is designed to carry axial forces, but it can also resist transversal forces by dowel action. This is usually neglected for simplicity's sake in the design phase, but it can be accounted for either expli ...

Designing Waste-Negative Floor Systems Made of Reused Saw-Cut Reinforced-Concrete Slab Elements

Corentin Jean Dominique Fivet, Célia Marine Küpfer

Building demolitions are often triggered by reasons independent of their structural conditions, causing the disposal of large quantities of reinforced concrete in good condition. Today, this concrete is, at best, crushed into aggregates, causing the loss o ...

Fatigue examination of reinforced-concrete bridge slabs using acoustic emission and strain monitoring data

Imane Bayane

The examination of bridges under service loading is key for understanding their condition and thus for their sustainable and efficient use. The need to extend the service duration of existing bridges is increasing, and therefore, efficient tools for examin ...

Performance of Embedded Bolt Shear Connectors

Scott Walbridge, Matthew James Sjaarda

A laboratory research program carried out at the University of Waterloo featured the testing of three large-scale steel-concrete composite beam specimens with embedded bolt shear connectors. A detailed assessment of the connector performance was made, faci ...

Numerical simulation of the probability of corrosion initiation of RC elements made of reinforcing steel with improved corrosion performance

Eugen Brühwiler, David Conciatori

Steel reinforcing bars in concrete are protected from corrosion by a thin oxide film that is created on the steel surface in the highly alkaline environment of the concrete. Corrosion process begins once this oxide film is destroyed, for example, by chlori ...

An analysis of the shear-transfer actions in reinforced concrete members without transverse reinforcement based on refined experimental measurements

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Cavagnis

A traditional difficulty in the understanding of the role of the various shear transfer actions in members without transverse reinforcement has been a lack of detailed measurements on the development of shear cracking and their associated kinematics during ...

Compressive Membrane Action Effects on Punching Strength of Flat RC Slabs

Aurelio Muttoni, Raffaele Cantone

The design of reinforced concrete flat slabs in practice can be governed at failure by punching shear close to concentrated loads or columns. Punching shear resistance formulations provided by codes are calibrated on the basis of experimental tests on isol ...

Shear strength evaluation of RC bridge deck slabs according to CSCT with multi – layered shell elements and PARC_CL Crack Model

Aurelio Muttoni, Raffaele Cantone

The shear resistance of RC slabs without shear reinforcement subjected to concentrated loads near linear support is usually calibrated on the base of tests on one – way slabs with rectangular cross section. However, the actual behavior of slabs subjected t ...

Advanced fatigue theory and structural response monitoring for safety verification of existing RC slabs subject to railway traffic

Vasileios Grigoriou

Experience has shown that when the models and methods that have been developed for the design of new structures are â blindlyâ used for the examination of existing ones, the management of civil infrastructure lacks substantially in financial efficiency ...

Analysis of Electromagnetic Fields Inside a Reinforced Concrete Building With Layered Reinforcing Bar due to Direct and Indirect Lightning Strikes Using the FDTD Method

Farhad Rachidi-Haeri, Marcos Rubinstein, Akiyoshi Tatematsu

Lightning electromagnetic pulse (LEMP) is a severe threat to sensitive electronic devices installed in buildings. To protect these devices from LEMP effects, the evaluation of the electromagnetic fields inside of the building is required. Although numerous ...

Development of a displacement-based design approach for modern mixed RC-URM wall structures

Katrin Beyer, Alessandro Paparo

The recent re-assessment of the seismic hazard in Europe led for many regions of low to moderate seismicity to an increase in the seismic demand. As a consequence, several modern unreinforced masonry (URM) buildings, constructed with reinforced concrete (R ...

Rotation capacity and stress redistribution ability of R-UHPFRC-RC composite continuous beams: an experimental investigation

Eugen Brühwiler, Talayeh Noshiravani

The results of tests on two continuous composite beams combining a reinforced concrete (RC) beam with a layer of reinforced ultra-high performance fiber reinforced concrete (R-UHPFRC) are presented. The R-UHPFRC element acts both as a tensile membrane and ...

The levels-of-approximation approach in MC 2010: application to punching shear provisions

Aurelio Muttoni, Miguel Fernández Ruiz

In order to address how new knowledge influences design expressions, design codes have in most cases become significantly more complex over the last decades. However, this tendency is leading to codes that are too complicated for preliminary design but sti ...
