PyPile is a lateral pile analysis software program based on p-y curve and finite element method. Pile deflection, bending moment and shear force can be analyzed with different load cases and multiple pile types.
PyPile has common pile cross sections and custom cross section. Typical soft clay, stiff clay, sand p-y curves (Barry J. Heyer and Lymon C. Reese, 1979), API sand, weak rock, c-phi soil, and custom p-y curve are included.
Free pile head, fixed pile head, and arbitrary boundary conditions at any pile depth are implemented. Concentrated load, moment, distributed load can be applied at any depth along piles. Nonlinear pile bending stiffness was also integrated in the program.
PyPile has undergone rigorous verification through extensive user application and benchmarking against existing commercial software. For detailed research and case studies, please refer to the Publications section. To get started, navigate to the program folder to find sample data files.
