PREDICTION OF ROW REDUCTION FACTOR OF PILE GROUPS UNDER LATERAL LOADING

There are various methods to evaluate the response of piles and pile groups under lateral loading. Rees method is one of the most conventional approaches in which p-y curves are used. One of the most common methods of accounting for the group effects in p-y method is to modify the single pile p–y curves using a p–multiplier, as suggested by Brown et al. (1988) [1]. In this approach, the soil resistance, p, is reduced by multiplying by a constant factor, P, as shown in Figure 1. (Each row has personal reduction factor because of group effects).
