Europe is characterised by a high level of seismic risk, both in terms of intensity and frequency, as evidenced by the significant damage caused to the region's building heritage. Italy is one of the most seismically active areas in the Mediterranean Basin, having experienced several destructive events in recent decades. Therefore, it is essential...

High energy demand forced many countries to reopen or expand production of electricity from coal power plants. Apart from being one of the most polluting technological processes emitting millions of metric tons of carbon dioxide in the atmosphere. This process also produces an enormous quantity of coal fly ash which has been successfully used as a...

Retaining structures in R. of North Macedonia until recently were only designed according to the concept of global safety factors, with the conventional methods of limit equilibrium. This method was widely used in ex-YU countries until Eurocodes have been published аs regulations in the country formal legislation, where there are prescribed differe...

This paper aims to describe the CRISIS web-based platform (WBP) in all its parts and functionalities. The platform is the main result of the two-year EU-funded project CRISIS (Comprehensive RISk assessment of basic services and transport InfraStructure). It has been developed by EUCENTRE (European Centre for Training and Research in Earthquake Engi...

Drained triaxial monotonic test is one of the most frequently used experiments in geotechnical engineering, mostly because its results are starting points for many research topics. This paper presents triaxial drained monotonic experiments on natural sand borrowed from the terraces of river Vardar, that passes through Skopje. This Skopje sand is hi...

One of the most popular themes in earthquake geotechnical engineering is the simulation considering the phase interaction among different phases inside the soil medium. The present article aims at providing numerical simulations of an earth fill dam composed of multiphase material models. Moreover, the assessment of liquefaction potential is invest...

The Location Tower is one of the three sites from the 3D seismic network originally installed in the 80’s which is recently re-established and enabled for real-time monitoring and recording acceleration data. The Location Tower is consisted of one surface and three downhole instruments up to 125 meters down the bedrock; a nine story building with t...

In recent years, the improvement of disaster and emergency management through building a harmonized and efficient system for risk assessment of structures in the cross-border region (CBR) has become increasingly popular. Harmonization of the risk exposure model for cross border regions is first and most important step for assessment of risk in the...

The potentially high vulnerability and poor performance of the existing buildings, after past seismic events, including exploitation period has raised awareness of the need to improve their seismic performance. Repair and strengthening gives new life to existing or ageing structures that might otherwise be demolished and replaced. This paper will a...

For the purpose of building a new electric power facility a project to determine seismic potential and seismic parameters for design is produced. Multiple in-situ geophysical investigations have been performed and soil samples have been taken to the laboratory where simple shear tests are done to determine the dynamic parameters of the soil layers....

Within the presented research, model tests were performed in 1-g conditions to investigate the liquefaction potential of Skopje sand as a representative soil from the Vardar River’s terraces in N. Macedonia. A series of shaking table tests were performed on a fully saturated, homogeneous model of Skopje sand in the newly designed and constructed la...

This paper presents the harmonized approach for landslide susceptibility and hazard assessment at the cross-border region between N. Macedonia, Albania, and Greece. The European ELsusv2 initiative is selected as a harmonized approach for regional landslide susceptibility mapping for the area study. The peak ground acceleration value within the slid...

This paper presents the harmonized approach for landslide susceptibility and hazard assessment at the cross-border region between North Macedonia, Albania, and Greece. The European ELsusv2 initiative is selected as a harmonized approach for regional landslide susceptibility mapping for the area study. An analytical relationship is used to assess th...

At 03:56 local time on November 26, 2019, an earthquake with a Mw = 6.4 struck western part of Albania. The duration of the tremor lasted less than 50 s and was felt largely also in Albania's capital Tirana, and in places as far away more than 300 km northeast of the epicenter. It caused damage to many public and residential buildings in districts...

Based on the elastic theory assumptions and averaging theories, an infinite element boundary which is frequency independent is derived for saturated soil media. The infinite element development is based on mapping functions and viscous layers for damping propagating waves of both solid and water phases. The newly developed infinite element is able...

Rapid advancements of information technology and data digitalization have contributed to faster data collection and analysis. At the same time, datasets can be very large and may continuously grow due to data updates or additional data collection, which makes their manual interpretation and analysis impossible. A large database provides an abundanc...

The long tradition of Danube‐European conferences obliges the geotechnical society to show highest respect to historical facts, as essential basis for further development. Having in mind that XVI Danube‐European Conference on Geotechnical Engineering (DECGE) is held in Skopje, it is good occasion to present some historical data connected with devel...

Based on the elastic theory assumptions, an infinite element boundary which is frequency independent is derived. The infinite element development is based on mapping functions and viscous layer for damping propagating waves. In numerical modelling the general finite element software ANSYS using its User Programmable Features (UPF) is used. Related...

This paper presents the influence of boundary conditions in numerical simulation of soilstructure interaction problems. It discusses aspects related to a seismic load influencing a soil medium and a frame structure resting on the soil. The soil conditions are represented by 30 m soft, medium, and dense soil deposits with four layers resting on bedr...

Landslides as secondary seismic effects are causing some patterns of soil failure that are often considered among the most destructive ones. In fact, the impact from triggered landslides has sometimes exceeded damage directly related to strong shaking and fault rupture. The objective of this research study is landslide hazard and risk assessment co...

This paper summarized the results of dynamic properties of the soil samples collected from one NPP site which is still under construction. Geotechnical aspects related with seismic safety of structures and foundation ground is important issues to be investigated. Recommendations and procedures given in IAEA Safety Standards Series No. NS-G-2.13 Eva...
