A structural analysis model for parallel-member wood joist floors is d
eveloped that includes the effect of component creep. Viscoelastic mat
erial models are calibrated using the data from a recently completed e
xperimental program conducted as part of this overall study. Using thi
s system model, deflection serviceability reliability analyses of para
llel-member wood systems, including the effects of creep deformation,
are conducted. Stochastic load models are used to simulate the time-va
rying nature of applied loads. Multiple limit state definitions for de
flection serviceability of parallel-member wood floors are considered.
Monte Carlo simulation is used to evaluate limit state probabilities.
Reliability indices for current serviceability design provisions are
also evaluated, and a serviceability system factor for Load and Resist
ance Factor Design (LRFD) is recommended.
