Data-driven 1D wave propagation for site response analysis

Jean-François Molinari, Antonio Joaquin Garcia Suarez, Sacha Zenon Wattel

Prediction of ground motion triggered by earthquakes is a prime concern for both the seismology community and geotechnical earthquake engineering one. The subfield occupied with such a problem is termed site response analysis (SRA), its one-dimensional fla ...

Fire performance evaluation of GFRP-balsa sandwich bridge decks

Niloufar Vahedi

Bridges are a critical component of national infrastructures and economies. A significant percentage of bridges built all around the world are made of reinforced concrete which according to building codes have a life span between 80-100 years. However, str ...

Constructional method of UHPC on steel deck of long span suspension bridge and in-situ experimental test

Jian Zhan

The Second Dongting Lake (SDTL) Bridge is the longest steel truss girder suspension bridge in China, which has a main span of 1480 m. To alleviate deterioration issues in the orthotropic steel deck (OSD), the steel-ultra high performance concrete (UHPC) li ...

A systematic approach to estimating traffic load effects on bridges using weigh-in-motion data

Alain Nussbaumer, Manfred Hirt, Matthew James Sjaarda

In contrast to the Swiss load model used for new bridge structures (SIA 261), which has roots in a Europe-wide weigh-in-motion (WIM) study and considers the full design life of new structures, the model for existing structures (SIA 269) from 2005 is derive ...

Monitoring of the UHPFRC strengthened Chillon viaduct under environmental and operational variability

Eugen Brühwiler

Constructed in 1969, the Chillon viaducts constitute a vital component of the Swiss roadway network. The bridge deck was strengthened in 2015 by means of an Ultra High Performance Fiber Reinforced Cement-based Composite for alleviating the effects of deter ...
