“…The trekking trails from Lukla to EBC were also remarkably damaged by co-seismic landslides (Miyamoto 2015). Besides, this tremor triggered 89 landslides along the 'Kathmandu Kyirong highway' (KKH) and 35 along the 'Araniko Highway' (AH) with the respective damage of 2.9 km and 1.4 km road, and 5 and 15 bridges (Quancai et al 2017;Xu et al 2017).…”

success rates, and 0.809, 0.890 and 0.760 for the prediction rates for respective pre, co and post seismic landslide susceptibility. The accuracy for seismic landslide susceptibility was better than pre and post-quake ones. It might be because of the differences on completeness of the landslide inventory, which might have been possibly done better for the single event based co-seismic landslide mapping in comparison with multitemporal inventories in pre and post-quake situations. The results obtained in this study provide insights on dynamic spatial probability of landslide occurrences in the changing condition of triggering agents. This work can be a good contribution to the methodologies for the evaluation of the dynamic landslide hazard and risk, which will further help to design the efficient mitigation measures along the mountain highways.

“…The proposed data is derived based on the information reported during 2015 Nepal earthquake event. Among these reports are the bottleneck problem ( [8] ), urgent medical supply demands ( [11] and [9] ), set-up of temporary shelters and field hospitals due to compromised buildings ( [4] and [11] ), damage to the road network ( [13] ) as well as the limited vehicle available for urgent medical supply delivery ( [5] ).…”

“…A bridge structure must maintain its operability both during and after earthquakes, as any failure of the bridge disrupts relief efforts, rescue operations and communication with surrounding areas. Recent destructive earthquakes in Iran, 1 Turkey, 2 Nepal, 3 China, 4 Japan, 5 New Zealand 6 and other countries, caused an extensive damage to the bridge substructures and revealed the extreme vulnerability of the bridges to seismic excitation. Given piers as the main vertical and lateral load‐bearing components in the bridge structure, their damage in earthquakes causes the total failure of the structure and occasionally devastation of the bridge.…”

Extensive damage to the bridges in recent earthquakes has revealed the vulnerability of these structures to the seismic excitation. Bridge piers play a key role in maintaining the operability of the bridge structure during and after earthquakes. As determinant elements in single‐pier bridges, wall piers significantly affect the bridge structure behavior. Hence, the present experimental study was conducted to examine the seismic performance of wall piers made of modern materials, that is, fiber reinforced concrete (FRC) in RC bridges. Eight wall piers made of steel fiber reinforced concrete (SFRC) with different aspect ratios, steel percentages and concrete strength were subjected to lateral load. The results showed that using SFRC reduced the steel strain within the serviceability range. Compared to conventional concrete, SFRC changes failure modes and deformational characteristics and also increases the energy dissipation capacity, stiffness in every drift values, load‐bearing capacity as well as yielding length.
