Re:Crete - A Footbridge made of Reused Concrete Blocks

Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer, Jan Friedrich Georg Brütting, Julie Rachel Devènes

Today, concrete is the most widely used construction material worldwide. Strong, versatile, durable, and vector of economic development, this exceptional material is also the principal cause of greenhouse-gas emissions, material depletion and waste generat ...

Study on Mechanical Performance of Prestressed UHPFRC U-Beam Bridges

Eugen Brühwiler

The forms of U-shaped UHPFRC beams have not been investigated for the highway footbridge. Compared with the traditional section forms, the U-shaped UHPFRC beams can reduce the material consumption under the condition of providing the same bearing capacity. ...

Overpass bridge of the L3378 road near Fulda-Lehnerz First application of UHPFRC in road bridge construction in Germany. Part 1

Eugen Brühwiler

Aging bridges of the German federal road network often cannot be rehabilitated or replaced timely due to insufficient funding and complex regulations of building laws. Consequently, novel building materials and alternative solutions get the opportunity to ...

Performance of Pedestrian-Load Models through Experimental Studies on Lightweight Aluminum Bridges

Scott Walbridge, Ann Christine Sychterz

Aluminum structures provide a high strength-to-weight ratio, are corrosion resistant, and are esthetically pleasing. Hence, their use in bridge construction has recently begun to increase, especially for pedestrian bridges. Because of their relative light ...

Deployment of a tensegrity footbridge

Ian Smith, Nicolas Willy Veuve, Seif Dalil Safaei

Deployable structures are structures that transform their shape from a compact state to an extended in-service position. Structures composed of tension elements that surround compression elements in equilibrium are called tensegrity structures. Tensegritie ...

A Bayesian Approach to Detect Pedestrian Destination-Sequences from WiFi Signatures

Michel Bierlaire, Bilal Farooq, Antonin Danalet

In this paper, we propose a methodology to use the communication network infrastructure, in particular WiFi traces, to detect the sequence of activity episodes visited by pedestrians. Due to the poor quality of WiFi localization, a probabilistic method is ...

Towards an activity-based model for pedestrian facilities

Michel Bierlaire, Bilal Farooq, Antonin Danalet

This paper develops a framework for understanding pedestrian mobility pattern from WiFi traces and other data sources. It can be used to forecast demand for pedestrian facilities such as railway stations, music festivals, campus, airports, supermarkets or ...

Determining Control Strategies for Damage Tolerance of an Active Tensegrity Structure

Ian Smith, Nizar Bel Hadj Ali, Sinan Korkmaz

Tensegrity structures are spatial, reticulate and lightweight systems composed of struts and cables. Stability is provided by a self-stress state between tensioned and compressed elements. Tensegrities have received interest among scientists and engineers ...

Deployment of a Pentagonal Hollow-Rope Tensegrity Module

Ian Smith, Landolf-Giosef-Anastasios Rhode-Barbarigos, Nizar Bel Hadj Ali, René Motro

Tensegrity structures are spatial reticulated structures composed of cables and struts. Tensegrity systems are good candidates for adaptive and deployable structures and thus have applications in various engineering fields. A “hollow-rope” tensegrity syste ...

Christian Menn's recent bridge designs - Reducing structural elements to the simplest solution

Eugen Brühwiler

The conceptual designs by Christian Menn of four landmark bridges are presented: 1) a 350-m span cable-stayed bridge with jointless deck girder, 2) a cable-stayed bridge with a single “spindle-shaped” pylon, 3) a bridge with an arch reaching high above the ...
