This paper formulates a theoretically consistent definition of the wind response spectrum based upon the equivalent wind spectrum technique, a calculation procedure by means of which wind is schematized as a stochastic stationary Gaussian process characterized by a mean velocity profile on which an equivalent turbulent fluctuation, perfectly coherent ...

Soil Dynamics and Earthquake Engineering, 2006
Abstract The response spectrum method (RSM) in earthquake engineering was conceived and then fully developed by M.A. Biot (1905–1985) during the period of about 10 yr, between 1932 and 1942. On the occasion of the 100th anniversary of Biot's birth, this paper reviews his contributions to earthquake engineering, and then briefly outlines the ...

Calculation of a shock response spectrum
2011 12th International Carpathian Control Conference (ICCC), 2011As it is stated in the ISO 18431–4 Standard, a Shock Response Spectrum is defined as the response to a given acceleration acting at a set of mass-damper-spring oscillators, which are adjusted to the different resonance frequencies while their resonance gains (Q-factor) are equal to the same value.

Consecutive combined response spectrum
Earthquake Engineering and Engineering Vibration, 2014Appropriate estimates of earthquake response spectrum are essential for design of new structures, or seismic safety evaluation of existing structures. This paper presents an alternative procedure to construct design spectrum from a combined normalized response spectrum (NRSC) which is obtained from pseudo-velocity spectrum with the ordinate scaled by ...

Separation of stages, the separation of the spacecraft from the last stage of the launch vehicle will induce very short duration loads in the internal structure of the spacecraft, the so-called shockloads. The duration of the shockload is, in general, very short with respect to the duration associated with the fundamental natural frequencies of the ...

Seismic response of structures by the response spectrum method
Nuclear Engineering and Design, 1981Abstract The problems of the acceleration profile at the lower elevations of cantilever structures and the response of relatively rigid structures are explored. It is shown that the use of the conventional methods for the above problems provide very approximate results.

Residual Displacement Response Spectrum
Journal of Structural Engineering, 1998Structures subjected to strong earthquake ground shaking may be left in a displaced condition. The amount of this residual or permanent displacement is determined by structural characteristics, including mass and hysteretic behavior, as well as ground motion.

Spectrum of autoimmune responses in systemic vasculitis.
Annali italiani di medicina interna : organo ufficiale della Societa italiana di medicina interna, 1992Growing evidence supports the inclusion of primary forms of systemic vasculitis within the category of autoimmune diseases. Thus their association with a family of autoantibodies, related to their specificity or neutrophil cytoplasm antigens, has been identified and the role these autoantibodies play in pathogenesis is now being explored.

An inverse shock response spectrum
Mechanical Systems and Signal Processing, 2011Abstract The shock response spectrum (SRS) is a tool commonly used by application engineers that characterizes the severity of a transient acceleration. Due to the definition of the SRS, neither an analytical nor a unique inverse exists for an arbitrary function.
