This dissertation contributes to the improvement of the predictive accuracy of the impact capacity of rockfall protection galleries and to the establishment of a performance-based design procedure for these structures. Furthermore, it facilitates the understanding ...

All over the world, ballasted railway tracks form one of the major transportation networks designed to provide heavy haul freight and passenger traffic. However, large cyclic loading from heavy axle trains operating at high speeds often causes excessive deformation ...

The aim of this research is to provide a better understanding of the dynamic response of rockfall protection galleries. This will improve the prediction accuracy of their impact load capacity. An analytical model based on a system of multiple degrees of freedom ...

The purpose of this research is to collect fundamental data and to establish a performance-based design method for reinforced concrete beams under perpendicular impact load.

<p>In Japan, slope disasters occur due to earthquakes, abnormal weather and inappropriate land development. It is important to identify safe and economical countermeasures against rockfall disasters. We developed a simple, long-lasting and low-cost structure ...

This paper presents the results of a simulation study of the effect of rock size and shape on impact distance, defined as the distance from the base of a slope to the first point of impact. This study is based on new algorithms which take into account the ...
