The Optimization of a Wooden Floor Design Based on Validated Finite Element Models

摘要

This paper describes a research project to develop a dowelled joist floor design which has a similar thickness to typical concrete floor constrictions in Switzerland but with better environmental life cycle impact and impact sound insulation below 200 Hz. The dynamic properties of the floor designs were evaluated using a systematic process of developing and then elaborating on initially simple finite element models which were validated based on experimentally determined material properties. This approach was successful with close agreement in both the mode frequencies and the MAC values. Results from the finite element analysis are presented as are the results from impact testing of full scale floor designs.
