作者: P Jeanjean 摘要: In this paper, an efficient method is proposed to derive cyclic p-y curves from either push-over or shaking table test results. The Fourier series function, satisfying the boundary conditions of a pile, is used to represent deflection behavior of the pile-soil system...
Fig. 1. Illustration of framework for deriving monotonic p-y curves from stress-strain response measured in DSS tests [11,29]. 2.2. The cyclic p-y approach Combining the concept of equivalent number of cycles Neq, which is defined as the number of cycles at the current load level that wo...
The cyclic response of foundations deviate from the behaviour predicted by macro-elements developed for monotonic loading. The macro-element by Nguyen-Sy [21], which was developed in the hyperplasticity framework for bucket foundations for OWTs consider cyclic loading, hence it is most relevant in ...
Model framework The PISA design model is concerned with computing the performance of a monopile foundation for the loading conditions shown in Fig. 1. A monotonic lateral load H is applied at a height h above the seabed level (referred to in this paper as ‘ground level’). The PISA model...
Within the framework of the analysis of phase diagrams, a superposition of phase transitions in the blends of amorphous and crystallizable polymers with a low critical separation temperature was considered. A superposition of phase separation and glass transition in such blends is accompanied by the ...
Unmodified muskeg has a density of 0.2 g·cm−3, which is strongly enhanced upon infiltration of the silica precursors and formation of the siloxane framework reinforced with various amounts of mulch and hydroxyethylcellulose (0.6–1.05 g·cm;−3 Table 1). In contrast, the density ...

According to the curves in Figure 22, the primary grain size that dominated in the samples is the size between the sieves of the (0.075) mm and (0.125) mm sizes, or the Phi values of four and three, respectively, with a percentage range of 50–90% of the sizes. This result shows ...
Fig.4ashows the shear stress-strain curves for intact clay under monotonic shearing. It is apparent that the undrained resistance of intact clay is strongly dependent on the shearing direction. The maximum shear resistance occurred atα=0° while the minimum shear stress resistance occurred atα=30...
