Response Spectrum Method for Nonlinear Surface Ground Analysis
Advances in Structural Engineering, 2004An equivalent linear response spectrum approach is proposed for nonlinear surface ground analysis. In contrast to the conventional method which deals with only a single ground motion for equivalent linearization of soil properties, it is argued in this paper that a design response spectrum defined at the upper level (bottom of the surface ground) of ...

Spectral Analysis Method of Seismic Waves: Time-Frequency Response Spectrum
International Journal for Housing Science and Its Applications, 2023The commonly used spectrum analysis methods are summarized and their problems are analyzed. In this paper, the time-domain response spectrum is first analyzed and the frequency-domain normalized spectrum is given. The normalized time-frequency response spectra are calculated and compared by four typical ground vibration waveforms. This project will use

Response Spectrum Method for Kinematic Soil-Pile Interaction Analysis
Advances in Structural Engineering, 2010The detailed seismic responses of pile-soil systems are usually evaluated by a three-dimensional finite-element model which requires a lot of computational resources. In the actual structural design for these models, a computationally efficient method with a reasonable accuracy is preferred from the viewpoint of cost and time.

Non‐linear response spectrum method for three‐dimensional structures
Earthquake Engineering & Structural Dynamics, 1988AbstractAn approximate non‐linear response spectrum method for the analysis of three‐dimensional structures is presented. The non‐linear effects are taken into account by employing an equivalent linearization criterion along with inelastic spectra and geometric stiffness matrices.

Seismic Response Analysis of Long Span Cable-Stayed Bridge by Response Spectrum Method
Applied Mechanics and Materials, 2012Based on response spectrum method, the seismic behavior of a long span cable-stayed bridge is investigated through three dimensional finite element model established by ANSYS. By calculating the cumulative effective mass factors of the bridge, the minimum number of modes used for modal superposition analysis is obtained.

Determination of floor response spectra on the basis of the response spectrum method
Nuclear Engineering and Design, 1977Abstract In this paper a method to determine floor response sepctra is proposed which is based on the modal analysis of a support structure with interaction-free, one-degree-of-freedom system attached. The time-consuming methods using real or artificial soil accelerations are avoided as well as some of the arbitrarinesses in the approaches of Biggs ...

Response Spectrum Method for Estimation of Peak Floor Acceleration Demand
Improving the Seismic Performance of Existing Buildings and Other Structures, 2009A response spectrum method to estimate peak floor acceleration demands of multistory buildings subjected to earthquakes and responding elastically is presented. Available response spectrum methods and modal combination rules such as SRSS or CQC have been used for estimation of relative displacement and inter-story drift demands but cannot be directly ...

New Conversion Method from Response Spectrum to PSD Functions
Journal of Engineering Mechanics, 1995A new approach to directly convert a target response spectrum to an equivalent power spectral density (PSD) function is presented that requires no numerical iterations. Following the same approximation scheme used in Monte Carlo simulations, the unknown PSD function is discretized and expressed as the sum of Dirac delta functions. The discretized power
