460 x 150 30 × 106 × 5000 Am = 36 Advanced Geotechnical Engineering Hence, the values of Am from 0–5 are computed as follows: Node Point (m) Depth, x in (cm) Am 1440 (3658) 1152 (2926) 864 (2195) 576 (1463) 288 (732) 0 (0) A0 = 662 A1 = 530 A2 = 397 A3 = 265 A4 = 132 A5 = 0 0 1 2 3 4 5 also C1 = 2 Pt 2 × 50,000 (∆x )3 = ⋅ (288)3 = 16 EI 80 × 106 (5000) To calculate displacements, we need to find Bm and Dm. The expressions for B2m, and B2m+1 are given below: B2 m = 6 + Am − B2 m 1 − B2 m −1 (4 − B2m − 3 ) and B2m+1 = B2m (4 – B2m–1) These expressions are used for values of Bm greater than B3.

1). 1b. It should be noted that such a beamcolumn idealization represents a linear superposition of effects of the column and the beam, and it does not take into account nonlinearity, which may lead to effects such as buckling. 1 shows a pile structure subjected to axial and lateral loads; it can be analyzed as a classical beam bending and column problem. Hence, we will first present closed-form solutions for the beam-bending problem that has been used to analyze laterally loaded single piles embedded in linear elastic soils.

The rotation about the x-axis (θx) represents torsion, which is described briefly below. 13d). These springs are assumed to be uncoupled. 14 shows the combined bending and axial loadings and the 1-D FE. 13 One-dimensional idealization of axially and laterally loaded pile. (a) Structure; (b) idealization; (c) generic element; and (d) translational and rotational springs. Here, the effects of lateral and axial loadings in respective axes can be coupled. However, for simplicity, they are evaluated separately and superimposed for overall effects on the behavior of the beam-column.
