Design of New Low-Carbon Floor Systems by Reusing Cut Cast-in-Place Concrete Pieces

Corentin Jean Dominique Fivet, Numa Joy Bertola, Célia Marine Küpfer

As floors typically account for the largest share of a building embodied carbon footprint, new strategies to build low-carbon floors must be developed and implemented. Among these strategies, the reuse of existing components is a promising circular approac ...

Quantification of influence of monitoring duration on measured traffic action effects on fatigue of RC deck slabs of road bridges

Eugen Brühwiler, Bartlomiej Wojciech Sawicki

The safety of existing bridges may be assessed using data from monitoring. The fatigue damage induced during observation period is extrapolated to the total service duration of a structure, and the reserve capacity is estimated. However, due to the randomn ...

Direct Visualization of Atomic-Scale Heterogeneous Structure Dynamics in MnO2 Nanowires

Kangning Zhao, Xin Peng, Yuyang Zhang

Manganese oxides are attracting great interest owing to their rich polymorphism and multiple valent states, which give rise to a wide range of applications in catalysis, capacitors, ion batteries, and so forth. Most of their functionalities are connected t ...

Influence of monitoring duration on measured traffic action effects on road bridges

Eugen Brühwiler, Bartlomiej Wojciech Sawicki

This paper analyses the influence of monitoring duration on the obtained results using two long term (2.5 years) monitoring campaigns. Two road bridges with different nature of traffic are considered: (a) a heavily loaded two-lane highway viaduct and (b) a ...

Numerical Simulation of Long Tailrace Tunnels in Hydropower Pumped Storage Plants

Daniel Kevin Pace

This thesis aims to improve the current situation in the Duge pumped-storage hydropower plant in Norway. In the Duge power plant, which has an installed capacity of 200 MW, the rotor of one of the two Francis reversible pump-turbines (Unit 1) experiences e ...

The influence of wear on the interaction between the cutting tools and the rock face

At present, the demand of long tunnels with high cover is growing. At these depths, a rock mass consists mainly on hard rocks, which are often excavated with hard rock TBMs, whose costs per meter are lower than conventional excavation methods. The excavati ...

Molecular motor crossing the frontier of classical to quantum tunneling motion

Harald Brune, Roland Widmer, Jan Prinz, Samuel Thomas Stolz

The reliability by which molecular motor proteins convert undirected energy input into directed motion or transport has inspired the design of innumerable artificial molecular motors. We have realized and investigated an artificial molecular motor applying ...

Thermomechanical behavior of underground energy infrastructures

Jacopo Zannin

The employment of geostructures as structural supports and as heat exchangers represent an effective, renewable and sustainable way to satisfy thermal needs of the built environment. The structural support of conventional geotechnical structures is coupled ...
