Random response to stochastic floor loading
Abstract In order to model random structural responses to floor loads, floor load-effects are modelled with regard to the randomness of the loads and of the influence functions relating loads to load-effects. The floor loading is represented by a stochastic process model, and influence functions are represented as random functions of distributed structural stiffnesses. Approximate expressions are obtained for the means and variances of floor-load-effects and related equivalent uniformly distributed loads. These expressions involve load parameters, stiffness parameters and influence factors derived from influence functions. Influence factors for deflections of several floor systems are tabulated and the practical application of the results is illustrated with calculations for the means and variances of the long-term deflections of two reinforced-concrete floor slabs. The proposed model is distinguished from a well-known load-effect model by its ability to account for the response randomness due to local fluctuations of stiffness. This ability is useful in modelling deflections and other load effects which might be significantly affected by random stiffness fluctuations.
