Abstract
A wood floor analysis methodology is described which utilizes a finite‐element mathematical model along with input parameters which can be obtained through nondestructive evaluation and the use of predictive techniques. The mathematical model is implemented through the computer program FEAFLO (Finite Element Analysis of FLOors). The comprehensive method was verified by comparing computed deflections under concentrated loads to measured results from 22 full‐sized experimental floor specimens built and tested in earlier studies. The analysis method predicts floor behavior far more closely and consistently than do other analysis methods which consider the stiffness of the loaded joist only. Consideration of both the component variability and the structural interaction in the floor were shown to be needed to accurately predict the response of wood floor systems. With the availability of this verified analysis method, along with results of studies under both concentrated and uniformly‐distributed loads, sufficient information now exists for the design profession to utilize a more rational analysis procedure for rectangular, simplysupported wood floor systems.Keywords
