A preceding companion paper[1] examined the experimental time-dependen
t service-load response of wood joist floor systems, including an asse
ssment of time-dependent deflections and load distribution. The result
s of the experimental program are used herein to develop an analytical
model for the time-dependent response of wood joist floors. Time-depe
ndent component (i.e. joist, sheathing and connection) models are deve
loped from component tests. These component models are then integrated
into a system model. The focus of this paper is to present the theore
tical basis for the rime-dependent system model, and illustrate its pr
edictive capabilities. The system model approximates the time-dependen
t system creep of parallel-member wood systems to an acceptable degree
of accuracy. Moreover, the model requires relatively little computer
time, thus making it suitable for use in a Monte Carlo simulation. (C)
