The earthquake that took place at 03:56 local time on November 26, 2019, with Mw = 6.4, struck the west part of Albania and caused heavy damages to many public and residential buildings in the districts of Durres, Tirana, Lezha, Shkodra, Diver, Berat and the surrounding areas. Immediately after the earthquake, teams from the Institute of Earthquake...

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...

The proper seismic design of bridge structural bearings and expansion joints enables avoiding high repair costs after earthquakes. The paper discusses some experiences of the authors in design of bridge bearings and expansion joints according to Eurocodes. Within the scope of the detailed design of several new road overpasses, railway underpasses a...

Horizontally curved concrete girder bridges have complex dynamic characteristics because of their asymmetry and non-uniform mass and stiffness distribution. Their seismic behaviour is considerably affected by various such as structural characteristics, radius of the superstructure curvature and local site conditions. The computational, three-dimens...

The response of a structure to seismic loading depends on its dynamic characteristics, and on the input ground motion. For low amplitude motion, materials behave linearly but as amplitude increases, non-linear behavior starts taking place altering the dynamic properties of the structures. It is well known that periods of vibration are important cha...

Structural bearings are important parts of bridge structures. Proper seismic design of bridge bearings enables avoiding high repair costs after earthquakes. The paper discusses some experiences of the authors in design of bridge bearings according to Eurocodes and EN1337 accompanying codes for structural bearings. Within the scope of the detailed d...

Most of the bridge structures are not designed to behave in the elastic range under the effect of strong earthquakes. These are designed to have a lesser capacity than that required for elastic behaviour under an earthquake so that they are expected to suffer structural damage due to their inelastic response to strong earthquakes. The inelastic res...

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...

Being located in the central part of the Balkans, Republic of Macedonia has an economically strategic position for the region. Conditions of bridges are therefore significant in assessment of the entire seismic risk for the regional transportation network. This paper deals with vulnerability of road bridges typical for the Republic of Macedonia by...

In conditions of increasing construction of building extensions in Republic of Macedonia, particularly for the last two decades, the issue of seismic stability and safety of such new “hybrid” structures is posed as an imperative. With the undertakings of different type of reconstructions, building enlargements, adaptations, etc. of existing structu...
