The paper pertains to a comparative study of the efficacy of three predictive models for progressive build-up of pore water pressure during cyclic loading. The equivalent cycle method using a standard weighting function, modified equivalent cycle method and experiment based model were used for assessing the generation of pore water pressure values during cyclic loading. Various cyclic loading patterns, such as, uniform sinusoidal, non-uniformly increasing, exponentially decreasing, wavy irregular artificial shear stress histories were used for computation of progressive built-up of pore water pressures using above predictive models. Use of the standard weighting factor curve for equivalent cycle method provides a very rough and approximate estimation of the values of the progressive built up pore water pressure. Therefore, a new weighting curve for Ottawa sand has been developed and presented in this article. The predicted values implementing the newly developed approach show very good agreement with experimental results.
