Jetann, Charles A., Thambiratnam, David P., Kajewski, Stephen L., & Farr, Andrew (2007) Frequency Response of Flat Post-tensioned Concrete Floors: Frequency Coefficient-Root Function Method.

Vibration is a serviceability limit-state for the design of suspended floor systems in buildings that is not well understood by many structural engineers, and is often ignored. Dynamic response is an important design consideration for slender, two-way floors, particularly for those of post-tensioned concrete construction. At present, there are no reliable design guidelines that deal with this problem. This paper describes a research program, which will enable the development of much needed design guidance on the dynamic behavior of suspended post-tensioned concrete floors. Results from this parametric investigation have led to the preliminary development of new approach for predicting the natural frequency of flat, post-tensioned concrete floor structures. This new method has been named, the Frequency Coefficient-Root Function (FCRF) method. The FCRF method is a revolutionary and convenient tool structural engineers can use to design for the vibration serviceability limit-state of cast-insitu, post-tensioned concrete floor systems.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
