Presented here is a numerical investigation of the influence of non-uniform soil conditions on a prototype concrete bridge with three bents (four span) where soil beneath bridge bents are varied between stiff sands and soft clay. A series of high-fidelity ...
At present, more powerful tools for numerical modelling and structural analysis are available for the use in fatigue design and assessment of complex structures. Taking advantage of these tools, structural hot spot stress approach (SHSS) can predict the fa ...
During the crossing of brittle rock formations at the Lötschberg base tunnel, failure phenomena have been observed both at the tunnel face and at the walls. A detailed analysis has been undertaken to explain these behaviours, based on the recent developmen ...
In this paper, a numerical model for the pushover analysis of in-plane loaded unreinforced masonry walls is presented. For the analysis of the walls, which consist of vertical piers connected by horizontal masonry spandrels, an equivalent frame model is ad ...
The key to extending the service life of a historical masonry bridge is an accurate examination of its actual performance. This paper presents a risk-based safety approach which introduces a risk matrix illustrating the risk presented by a structure as a f ...
Seismic wave propagation in granular soils can induce large strain amplitudes in case of strong earthquakes. Seismic motions are irregular in frequency content and in amplitude, and have three different components in orthogonal directions. In this context, ...
Today all major standards implicitly or explicitly include an “impact factor”, “dynamic amplification factor” (DAF) or “dynamic load allowance”. The amount of dynamic traffic action represented by the factor varies considerably [6, 7]. The values are usual ...
We present a novel analysis of time-resolved extended x-ray absorption fine structure (EXAFS) spectra based on the fitting of the experimental transients obtained from optical pump/x-ray probe experiments. We apply it to the analysis of picosecond EXAFS da ...
In recent years, the necessity of using renewable resources and sustainable solutions in the building sector has become obvious, and interest in timber as a building material has revived. Novel timber-derived products, such as massif block panels, have eme ...
