Continuous safe and low-cost operation of structures extensively depends on their proper maintenance and management. To apply optimal management strategies for the existing structures, accurate assessment of their present and future safety is important and crucial. Hence, monitoring of structures can be considered a necessary condition for providin...

Influence of railway induced vibrations on structures and humans in urban areas Railway traffic is a significant source of vibration that can affect the quality of life of people living near busy railways. This study proposes an integrated methodology for analysing the impact of vibrations from railway traffic on people and nearby buildings and mea...

Both for newly constructed buildings and existing ones, it is desirable to measure the real dynamic properties to better understand their response in case of seismic events. Also, they represent comprehensive base for validation of an analytical model, for the purpose of assessment, strengthening or health monitoring. This paper presents the method...

Railway traffic-induced vibrations are becoming one of the major environmental concerns in urban areas. Such vibrations may affect the quality of life of people settled in the vicinity of railway lines with frequent traffic. This paper contains the results from the research conducted by in-situ measurements and numerical modelling of railway traffi...

Shaking-table tests of various upgrade systems applied on existing two-story RC structures have been performed at the Institute of Earthquake Engineering and Engineering Seismology-IZIIS, Skopje. The influence of each different upgrade system on the integral structural behavior has been investigated comparatively, conducting a total of 177 dynamic...

Testing of structures to understand their behavior under seismic conditions can provide an important source of information for safe and economical design and for dynamic properties of the structure. The need for testing the behavior of full scale structures under dynamic loads stems from the fact that the analytical calculations cannot account for...

Presented in the paper are the results obtained by experimental in-situ testing of four selected historical monuments in the region ofAbruzzo damaged during the earthquake in 2009.Ambient vibration testing method was applied to obtain their dynamic characteristics: natural frequencies, mode shapes of vibration and damping coefficients.The testing o...
