A simplified multisupport response spectrum method
Earthquake Engineering and Engineering Vibration, 2012A simplified multisupport response spectrum method is presented. The structural response is a sum of two components of a structure with a first natural period less than 2 s. The first component is the pseudostatic response caused by the inconsistent motions of the structural supports, and the second is the structural dynamic response to ground motion ...

A modified response spectrum method based on uniform probability spectrum
Bulletin of Earthquake Engineering, 2018The traditional response spectrum method (RSM) based on the mean peak spectrum (MPS) requires the assumption of equal modal peak factors, which may exert a major impact on the accuracy of the mean peak responses of structures under seismic excitation. The inherent reason behind this lies in the fact that no uniform probability of exceedance exists for ...

Response spectrum methods in tank-vehicle design
Experimental Mechanics, 1995Existing design rules for tank vehicles have proved insufficient, because vibrations often cause fatigue cracks. Measurements have been performed on the tank to provide a picture of the influence of different road types and filling ratios. Shock response spectrum analysis (SRS) was used to obtain a measure of single-dynamic events.

Response Spectrum Method for Submerged Structures
Volume 8: Seismic Engineering, 2008A submerged structure has virtual mass matrix in the inertial term and wet mass matrix in the driving term in the equation of motion, whereas a dry structure has the same mass matrix in these two terms. If a finite element code for dry structures is used to analyze a submerged structure, the results should be adjusted.

Response spectrum method for nonclassically damped systems
Nuclear Engineering and Design, 1986Abstract For nonclassically damped systems a modal superposition method which makes use of complex mode shapes and frequencies is presented in a companion paper [1]. The method is extended into a response spectrum formulation in this paper. Each complex mode shape and its conjugate result in two real vectors.

A Spectrum-to-Spectrum Method for Calculating Uniform Hazard Floor Response Spectra
Volume 8: Seismic Engineering, 2017In codes’ provisions and design procedures for acceleration-sensitive nonstructural components, seismic demand is commonly defined by means of floor response spectra expressed in terms of pseudo-acceleration. Depending on the considered analysis method, floor response spectra may be derived from floors’ acceleration histories, based on structural ...

Probable simultaneous response by the response spectrum method of analysis
Nuclear Engineering and Design, 1977Abstract A new method is proposed by which any response at any location in a structure which is expected to occur simultaneously with a maximum probable response at a given (or reference) location can be calculated.

Response spectrum method for multi‐support seismic excitations
Earthquake Engineering & Structural Dynamics, 1992AbstractA new response spectrum method is developed for seismic analysis of linear multi‐degree‐of‐freedom, multiply supported structures subjected to spatially varying ground motions. Variations of the ground motion due to wave passage, loss of coherency with distance and variation of local soil conditions are included.

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.

Inelastic Response Evaluation Method of Equipment Considering Peak Broadening of Response Spectrum
Volume 5: Operations, Applications, and Components; Seismic Engineering; ASME Nondestructive Evaluation, Diagnosis and Prognosis (NDPD) Division, 2022Abstract In order to evaluate seismic responses considering the elasto-plastic properties of equipment and piping systems, nonlinear time history analyses are utilized. When the analyses are used for seismic evaluation of equipment and piping systems in nuclear power plants, it is required to consider the uncertainty in the frequencies ...
