Interest in measuring displacement gradients, such as rotation and strain, is growing many areas of geophysical research. This results an urgent demand for reliable field-deployable instruments these quantities. In order to further establish a high-quality standard strain measurements seismology, we organized comparative sensor test experiment that took place November 2019 at the Geophysical Observatory Ludwig-Maximilians University Munich Fürstenfeldbruck, Germany. More than 24 different...

For decades, coal mining in the Upper Silesian Coal Basin (USCB) Poland has been inducing annually more than 150 seismic events with local magnitude M > 2. Two sets of sensors were installed USCB to measure angular velocities and translational accelerations from induced by underground mining. In period December 2015 November 2016, 503 recorded between 1.1 3.5. Analysis measurement data for seismicity confirmed a strong linear correlation peak ground acceleration shear S-waves, PGA motion...
This article presents a concise review of the methods to obtain spectral densities rotational components seismic ground motion from both translational and wave propagation parameters. The are obtained by decomposing at site into body surface contributions with random amplitudes. To rotation resulting stochastic fields waves differentiated respect spatial coordinates. Assumption plane radiating point source leads two components: rocking around horizontal axis perpendicular source-site...
This note describes the rotational seismic load definition as included in Part 6 of Eurocode 8 (EC8.6, 2005). The 8, 2005), ground-motion component depends upon structural subsoil compliance, which is controlled by shear-wave velocity top 30 m ground. A comparison effects rocking ground motion and horizontal on response a 160 m reinforced concrete chimney shows that for motion, excitations contribute significantly to overall structure. engineering code formulas however, should be calibrated...
Preliminary results of an application rotation rate sensors in dynamic identification a vibrating beam are reported. Three rotational sensors, measuring the response cantilever to kinematic harmonic excitations applied reconstruction its stiffness. A successful 15% stiffness drops is demonstrated. With development angular and decrease their cost one can expect further progress this new area vibration-based damage detection.
The recent rapid development of rotation rate sensor technology opens new opportunities for their application in more and fields. In this paper, the potential rotational sensors modal analysis full-scale civil engineering structural elements is experimentally examined. For purpose, vibrations two 6-m long beams made ultra-high performance concrete (UHPC) were measured using microelectromechanical system (MEMS) sensors. excited to an impact hammer a dynamic vibration exciter. results...

Random vibrations of a bridge structure under propagating, seismic excitations are considered and joint effects pseudostatic dynamic studied. Respective matrix equations motion derived. Detailed numerical analysis four-span modeled as three-dimensional (3D) frame kinematic wave with an oblique angle propagation is carried out. Key parameters loads identified their effect on both displacement force response analyzed. The root-mean-square normalized respect to uniform excitations. stays...
