Response spectrum analysis for floor acceleration
Earthquake Engineering and Structural Dynamics, 2015SummaryThe 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.

Acceleration response spectrum for predicting floor vibration due to occupants jumping
Engineering Structures, 2016Abstract This paper proposes an acceleration response spectrum to predict floors’ responses due to occupants jumping. Experiments were conducted on individual jumping loads resulting in 506 records. Each record was applied to a single-degree-of-freedom system with various frequencies and damping ratios to obtain a corresponding acceleration response ...

Analysis of RMS Acceleration Response Spectrum for Random Pedestrian Loads
Advanced Materials Research, 2011Pedestrian loads are affected by such uncertain parameters as walking step frequency, step length, dynamic load factors and phases of harmonic components, which lead to the uncertainties of structural response. A new method for calculation random response spectrum based on uniform design is introduced to reduce calculation work.

A response spectrum method for peak floor acceleration demands in earthquake excited structures
Probabilistic Engineering Mechanics, 2016This paper addresses the prediction of the median peak floor acceleration (PFA) demand of elastic structures subjected to seismic excitation by means of an adapted response spectrum method. Modal combination is based on a complete quadratic combination (CQC) rule.

Response spectrum of incompatible acceleration, velocity and displacement histories
Earthquake Engineering and Structural Dynamics, 2001The ground motions induced by an earthquake are expressed by the histories of acceleration, velocity and displacement. It is generally assumed that the acceleration, velocity and displacement histories contain identical information, i.e. the velocity history is obtained by integration of the acceleration history, and the displacement history is ...

Acta Seismologica Sinica, 2004
The seismic intensity attenuation relations in northeastern Tibetan Plateau region are established by a regression analysis on isoseismal data. Then the attenuation relations for horizontal peak ground acceleration and short-period response spectrum for western North America are derived based on the database of HUO Jun-rong and strong motion data from ...
