Response spectrum analysis for floor acceleration
Earthquake Engineering & 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 ...

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

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.
