I am so excited to release the first version of LEMSlope today. I believe LEMSlope will provide geotechnical engineers with new slope analysis experiences.
The initial motivation for creating LEMSlope is to have a declarative way to define the model geometry for slope analysis and free engineers from tedious geometry calculation, especially for design projects, in which many iterations of adjustment are required.
To ensure the declarative nature of model definition and maximize the flexibility, Python, as one of the most popular script languages in the world, is selected as the script language for LEMSlope. Many young engineers and student are familiar with Python. Even if you don’t know Python, the simplicity of the language should not steepen the learning curve too much.
Each analysis model, defined with the script, consists of one base case and one or many analysis cases. The analysis cases are based on the base case and modified with fill, excavation, phreatic surfaces, loads, and different materials.
The default script in the program should be able to provide users with a general idea about how the script structure looks like. Many example files are available in the example folder with the program package. The function cheat sheet in the program provides a list of all the modelling functions and associated function explanation.
Since this is the very first version, many functions are still in the todo list. If you think any functions need to be prioritized, please leave me a message or send me an email. Enjoy!
Compared to uniform piles, tapered pile has a varied pile width and varied bending stiffness along the pile length. Since usually the angle of tapering is relatively small, the lateral soil resistance affected by the pile width variation is relatively small. To analyze tapered pile under lateral load with PyPile 0.8.5, one can simply changes the pile bending stiffness along the pile length through User Defined Function bending stiffness type.
I am very happy to announce that BSTunnelLining is released today.
BSTunnelLining is a finite element modeling program using beam and spring elements to analyze multi-ring segmental tunnel linings.
This is just the very first version of BSTunnelLining. I believe that there will be many aspects of it required to be improved or implemented. I am more than happy to hear from you if you have any questions, suggestions, or comments.
I am very happy to announce PyPile 0.8.0 is released today.
After a long period of quiet time, I am so excited to announce the release of PyPile 0.7.0. Some significant changes and new functions will be discussed below.
Finite element method is implemented to replace the original finite difference method. FEM brings much higher flexibility for current functions and higher future extensibility for PyPile.
With this new release, lateral single ground springs, rotational springs, distributed springs provided by soils can be assigned to any depth along the piles. Piles can be fixed for lateral movement and rotation at any depths.
Concentrated lateral loads and moments, distributed lateral forces can be assigned to any depths along the analyzed piles. Distributed forces generated by relative soil movement can be easily applied to piles.
Distributed force generated by relative soil movement can be exported and used as input in other software programs, such as slope stability analysis programs.
In addition, weak rock and c-phi soil models are also implemented in this release.
I am happy to announce that Frost1D 0.1.0 is released. Hopefully it can help engineers or researchers for projects in the cold or relatively cold regions.
Frost1D is a one dimensional frost penetration analysis program. It can analyze multi-layered materials with various boundaries. Built-in fine and coarse grained soils, general freezable material and simple material can meet various project requirements.
I am happy to announce PyPile 0.4.0 is released today.
With PyPile 0.4.0, users can analyze laterally loaded piles with: 1) axial pile head loads; 2) English units; 3) result graph export to svg, emf, pdf, and png formats; 4) more HP pile types; 5) some other minor improvements.
Please feel free to let me know if you have any questions, suggestions, recommendations, or bug reports. Thank you for your support!
I am happy to announce that PyPile 0.3.0 has been released today and available for download from the Download menu.
Multiple piles can be analyzed in one run with PyPile 0.3.0; analysis results for all piles are summarized in one excel file. HP piles are added in the cross section types and the HP pile library is editable for end users. As requested by some users, load generation tool is back on the load dialog. Analysis result can also be viewed in the Result Data tab of the main window next to the Result Graph tab now. Some other minor improvements and bug fixes are also included in this release.
