A quantitative evaluation of the damage potential ground motions to structures can provide a basis for selection input motions. To determine main factors influencing ranking motions, corresponding effect were analyzed. First, structural period range from 0.05 10 s was divided into three types ranges based on an improved Newmark–Hall spectrum. The intensity measures (IMs) that characterize in ev...

Abstract The cavitation regime has a substantial influence on the damage potential, thus it to be considered in any specific investigation. For this purpose, we set up test rig at Technische Universität Darmstadt using Circular Leading Edge hydrofoil (CLE) analyse potential of sheet and cloud cavitation. Exceeding critical Reynolds number Re c , transitions from harmless aggressive High-speed r...

In intense-light systems, the traditional discrete optical components lead to high complexity and cost. Metasurfaces, which have received increasing attention due ability locally manipulate amplitude, phase, polarization of light, are promising for addressing this issue. study, a metasurface-based reflective deflector is investigated composed silicon nanohole arrays that confine strongest elect...

in this paper, the capabilities of displacement curvature derived from static response data for finding the location and severity of damage in euler-bernoulli beams are assessed. static response of a beam is obtained using the finite element modeling. in order to reduce the number of measured nodal displacements, the beam deflection is fitted through a polynomial function using a limited number...

A model for investigation of the optimal economic life cycle of grass leys with winter damage problems in northern Norway and the threshold of winter damage before it is profitable to reseed grasses is presented. A 2-level hierarchic Markov process has been constructed using the MLHMP software. The model takes uncertainty concerning the yield potential, damage estimation and weather dependent r...
