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 ...

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 ...
