“…This approach allows analyzing single piles with free or fixed head Huang et al [43] and Wu et al [58] thus assigned a reduced flexural rigidity to the relevant section of the pile to simulate cracking. The reduced values of E p I p were necessary in both cases to achieve a suitable match between the load versus deflection curve obtained in their analysis and that measured during the lateral load test (Figure 10).…”

“…Note that in the work of Huang et al [43] the load of 1462 kN was identified as the value at which corresponds the beginning of cracking in the concrete, and therefore there is a progressive decrease in the flexural rigidity EpIp. Huang et al [43] and Wu et al [58] thus assigned a reduced flexural rigidity to the relevant section of the pile to simulate cracking. The reduced values of EpIp were necessary in both cases to achieve a suitable match between the load versus deflection curve obtained in their analysis and that measured during the lateral load test (Figure 10).…”

Featured Application: An analysis method has been developed to study single piles under horizontal loading. The proposed method is innovative because it considers the highly non-linear response of circular reinforced concrete pile sections, taking also into account the influence of tension stiffening, and considers suction for partially saturated soil conditions. Abstract: A hybrid BEM-p-y curves approach was developed for the single pile analysis with free/fixed head restraint conditions. The method considers the soil non-linear behaviour by means of p-y curves in series to a multi-layered elastic half-space. The non-linearity of reinforced concrete pile sections, also considering the influence of tension-stiffening, has been considered. The model reproduces the influence of suction by increasing the stress state and hence the stiffness of shallow soil-layers. Suction is modeled using the Modified-Kovacs model. The hybrid BEM-py curves method was validated by comparing results from data of 22 load tests on single piles. In addition, a detailed comparison is presented between measured and computed data on a large-diameter reinforced concrete bored single pile.

A Boundary Element Method (BEM) approach was developed for the analysis of pile groups. The proposed method includes: the non-linear behavior of the soil by a hyperbolic modulus reduction curve; the non-linear response of reinforced concrete pile sections, also taking into account the influence of tension stiffening; the influence of suction by increasing the stiffness of shallow portions of soil and modeled using the Modified Kovacs model; pile group shadowing effect, modeled using an approach similar to that proposed in the Strain Wedge Model for pile groups analyses. The proposed BEM method saves computational effort compared to more sophisticated codes such as VERSAT-P3D, PLAXIS 3D and FLAC-3D, and provides reliable results using input data from a standard site investigation. The reliability of this method was verified by comparing results from data from full scale and centrifuge tests on single piles and pile groups. A comparison is presented between measured and computed data on a laterally loaded fixed-head pile group composed by reinforced concrete bored piles. The results of the proposed method are shown to be in good agreement with those obtained in situ.
