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 ...

Acceleration response spectrum for predicting floor vibration due to occupant walking
Journal of Sound and Vibration, 2014Abstract Annoying vibrations caused by occupant walking is an important serviceability problem for long-span floors. At the design stage the floor׳s structural arrangement may frequently change to cater for the owner׳s varying requirements. An efficient and accurate approach for predicting a floor׳s acceleration response is thus of great significance.

Earthquakes and Structures, 2012
The spectral representation method is a quick and versatile tool for the generation of spatially variable, response-spectrum-compatible simulations to be used in the nonlinear seismic response evaluation of extended structures, such as bridges. However, just as recorded data, these simulated accelerations require processing, but, unlike recorded data ...

Acceleration response spectrum for prediction of structural vibration due to individual bouncing
Mechanical Systems and Signal Processing, 2016Abstract This study is designed to develop an acceleration response spectrum that can be used in vibration serviceability assessment of civil engineering structures, such as floors and grandstands those are dynamically excited by individual bouncing. The spectrum is derived from numerical simulations and statistical analysis of acceleration responses

Estimation of strength reduction factors via normalized pseudo‐acceleration response spectrum
Earthquake Engineering & Structural Dynamics, 2006AbstractEstimation of design forces in ductility‐based earthquake‐resistant design continues to be carried out with the application of response modification factors on elastic design spectra, and it remains interesting to explore how best to estimate strength reduction factors (SRFs) for a design situation.

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.

Abstract Mode truncation is often used in seismic structural analyses of the classically as well as the nonclassically damped structures. In some cases, however, it can introduce significant error in calculated response due to the, so-called, missing mass effect.

Response spectrum of incompatible acceleration, velocity and displacement histories
Earthquake Engineering & 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 ...

Abstract The dynamic response of pavement, especially in term of vibration, provides information on pavement damage prediction, noise control and so forth. The vibration of pavement is also a potential energy which can be collected by energy harvester and utilized by sensing technology to obtain information of traffic and pavement conditions. In this
