Response spectrum analysis for floor acceleration

Earthquake Engineering & Structural Dynamics, 2015
SummaryThe peak floor acceleration (PFA) is a critical parameter influencing the performance of non‐structural elements in buildings. This paper develops a response spectrum analysis method based on the complete quadratic combination (CQC) rule to estimate the PFA.

Improved response-spectrum analysis of base-isolated buildings: A substructure-based response spectrum method

Engineering Structures, 2018
Abstract Unsatisfactory numerical predictions may result from applying the classical modal analysis in conjunction with the response-spectrum-method (RSM) to nonclassically-damped systems such as base-isolated buildings. This inaccuracy is highlighted by comparing the conventional RSM outcomes with results from nonlinear time-history analyses ...

Probable simultaneous response by the response spectrum method of analysis

Nuclear Engineering and Design, 1977
Abstract 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.

Generalized Response Spectrum Analysis for Structures with Dampers

Earthquake Spectra, 2018
In this study, a computational seismic design routine is proposed based on a generalized response spectrum analysis for highly indeterminate structures with energy-dissipation members, such as viscous or elasto-plastic dampers. Complex stiffness terms are introduced to account for displacement-dependent damping, and a three-dimensional (3-D) element ...

Detecting seismic response signals using singular spectrum analysis

SPIE Proceedings, 2010
Singular Spectrum Analysis (SSA) is a novel non-parametric technique based on principle of multivariate statistics. The original time series is decomposed into a number of additive time series, each of which can be easily identified as being part of the modulated signals, or as being part of the random noise.

Evidential Uncertainty Quantification of Dynamic Response Spectrum Analysis

Applied Mechanics and Materials, 2014
This study presents an evidential uncertainty quantification (UQ) approach for dynamic response spectrum analysis of a structural system with epistemic uncertainty. The present method is performed using an evidence theory to quantify the uncertainty present in the structures parameters such as material properties.

Earthquake analysis by response spectrum superposition

Bulletin of the Seismological Society of America, 1962
abstract Although earthquake response spectra can be used to determine the maximum response of structures having one degree of freedom, they provide only an approximate indication of the maximum response in multi-degree systems. In this paper, two different methods of approximating the maximum response, both based on superposition of the

Modal Response Spectrum Analysis

2015
In this example, the modal response spectrum (MRS) method of analysis is used to analyze a sixstory moment resisting frame. The analysis is performed in accordance with Section 12.9 of ASCE 7. The results from the MRS analysis are compared to the results obtained from an equivalent lateral force (ELF) analysis of the same frame.
