Performance of Roads In Seismic Conditions: A Theoretical And Experimental Study

As is well known, the role of the road network during and after an earthquake is of paramount relevance. In the light of the above, the main goal of the paper has been confined to the analyses of road performance in seismic conditions, as a result of intrinsic (structural and functional conditions, redundancy, etc.) and extrinsic (loads, flows, etc.) characteristics. Such interaction has been analysed for the area of Reggio Calabria and Messina Strait, through 28 equations and a number of models and simulations. Analyses proved that redundancy is a key-factor, able to affect the overall performance of the road network. Simulations demonstrated that in the long term road serviceability could be partly compromised, but accident risk, due to speed limitations, could result decreased
