Investigation of P-Y curve changes for analysis of reinforced concrete piles under lateral load due to different pile conditions

Article abstract:

These curves are based on laboratory research, according to the P-Y parameters of one of the methods of pile analysis under lateral load, using curves.
Has been stated. But different APIs such as type, density and shear strength of soil, pile diameter and depth, by different researchers and regulations such as regulations
It seems that other parameters are also effective in the behavior of the pile under lateral load, including the hardness, type, behavior of materials and the support conditions of the pile
Pile and soil modeling is continuous environment. In this, he mentioned P-Y as well as the amount of vertical load on the candle. Another way to calculate a curve
For pile modeling (with COM method, the effect of all the above parameters can be easily examined. In this study of male finite element software
The use of the fiber element) and the surrounding soil (using the element of 20 cubic nodes) have been used. After comparing the results of male software with the results
It has been studied by parametric study. Laboratory P-Y and software and model validation, the effect of different parameters on the curves
The results are also compared with the regulatory relations.
