Overview of current progress in the field of seismic regulations for the design of tunnel structures revealed that, despite significant progress in research work on seismic analysis of tunnels over the past few decades, however, a deficiency of systematic and precisely defined rules for the seismic design of tunnels still exists even in the most de...

In this paper, an analysis of the phase construction of a tunnel with support in static and seismic conditions is made. The PLAXIS 2D software package was used for the problem's numerical modelling. A parametric analysis of the excavation using the deconfinement method (1-ß) was made on an actual tunnel with support in the excavation phase an...

In many countries, reinforced concrete (RC) frames are widely utilized as the primary building structure. The infill is typically composed of traditional masonry (brick elements connected with mortar), commonly without isolation from the frame. It is noted that in engineering practice, seismic force calculations for RC frame buildings are often con...

On December 29, 2020, a shallow magnitude 6.2 earthquake struck northern Croatia near Petrinja. This earthquake was preceded by a strong foreshock with a magnitude of 5. In response to the Petrinja earthquake, a team of European geologists and engineers from Croatia, Slovenia, France, Italy, and Greece was promptly mobilized to conduct a thorough a...

The paper is dedicated to the modeling of tectonic movements based on GNSS coordinate time series, which were analyzed using the Kalman filter. The research area includes the territory of Japan, which is one of the most seismically active regions on Earth. The devastating Tohoku earthquake of 2011 was the result of subduction between the Pacific an...

Geodesy and its high precision are important instruments for the study of active tectonics and the presentation of the movement of solid parts of the earth. Deformations caused by earthquakes represent essential information for defining seismogenic zones. Precise measurements must be made on the wall of the fault itself or the system of connected a...
