Create milestones for the project

[mortenengen]

Edited June 2nd, 2023

We plan to track the progress of the project using milestones. What should these milestones be?

We suggest to use milestones for grouping issues and pull requests in related topics.

We suggest to adopt continuous integration, providing fast releases, so linking milestones to releases is perhaps not necessary. However, milestone # 0 is related to the framework of the package, and upon completion could mark the initial stable release, 0.0.1. We suggest that further releases, that should be incremental upon merging PRs, should follow semantic versioning.

We suggest that the milestone numbering could indicate the timeline, but not necessarily indicate consequentiality, i.e. milestone # 3 does not require milestone # 1 and # 2 to be completed, however, milestone # 2 requires # 1 to be completed, since # 2 is related to integrating # 1 in the package framework.

0 Framework → 0.0.1

• Naming conventions: recommended rules that need to be followed in naming classes and functions in the public namespace.
• Material classes: MC2010 Concrete, EC2 Concrete, MC2010 Reinforcement, EC2 Reinforcement
• Section classes: Rectangular reinforced concrete, generic reinforced concrete section
• Structural element classes: column, straight beam
• Framework for documentation
• Documentation for material, section and structural element classes

1a EC2 2023: Properties and property development

• Property development: strengths, stiffnesses, creep, shrinkage, etc.
• Constitutive relations
• Design strengths

1b EC2 2023: Ultimate limit state

• Stress distribution for ULS
• Transverse shear ULS
• Torsion ULS
• Punching ULS
• Combined actions ULS: bending, axial, shear
• Slender members
• Prestressing losses

1c EC2 2023: Serviceability limit state

• Crack width calculations
• Minimum reinforcement
• Deflection calculations

1d EC2 2023: strut and tie and detailing

• Reinforcement detailing
• Strut and tie modelling

1e EC2 2023: Fatigue

• Fatigue

1f EC2 2023: Misc

• Durability?

2a Integrate EC2 2023 in the framework

• Material classes
• Section classes? Depends on how this is implemented in #0.
• Structural element classes? Depends on how this is implemented in #0.

3 MC2020

...

4 Integrate MC2020 in the framework

...

etc. for EC2 2004 and MC2010

Another proposal for the milestones:

Milestone 1: Example code to set the template (release 0.1).

For this milestone we define the structure of the computer code, conventions, etc., which is illustrated for a couple of design clauses. This milestone is meant to showcase the whole idea to others and to provide clear example code for potential new team members. We expect to reach this milestone in short time.

In this milestone we realized:

• Main structure of the computer code
• Naming conventions
• prEN1992-1-1:
  • Code formulas (level 1) on crack width calculations
• fib Model Code 2010:
  • Code formulas (level 1) on creep and shrinkage
  • Code formulas (level 1) on shear resistance
• EN1992-1-1:
  • Code formulas (level 1) on shear resistance

Milestone 2: Code formulas fib Model Code 2020 + examples (release 0.2).

For this milestone we implement all ULS and SLS code formulas (level 1) and material classes (level 2) of the fib Model Code 2020. Furthermore, we connect to the fib task group that work out different calculation examples with the new Model Code, and elaborate these examples with our computer code. We expect to reach this milestone in xxx of 2024.

In this milestone we realized:

• ULS and SLS code formulas fib Model Code 2020 (level 1)
• material classes fib Model Code 2020 (level 2)
• example calculations

Milestone 3: Code formulas prEN1992-1-1 + examples (release 0.3).

For this milestone we implement all ULS and SLS code formulas (level 1) and material classes (level 2) of the prEN1992-1-1. Furthermore, we elaborate different calculation examples (similar as in milestone 2) using the new Eurocode 2 with our computer code. We expect to reach this milestone in xxx of 2024.

In this milestone we realized:

• ULS and SLS code formulas prEN1992-1-1 (level 1)
• material classes prEN1992-1-1 (level 2)
• example calculations

Hi. As a new member on this project I would like to see some text explaining the vision and motivaion for this work, what the aim currently is, and how we envision this program/code to be used for the end user (are we doing only one calculation or several millions when we run the program).

Thanks for the comment, @slobbeat. We have updated the initial comment above based on your input 😃

[mortenengen]

I have created milestones related to the package framework, and also Eurocode 2 2023 based on a brief review by @talledodiego and myself. We should do the same for fib Model Code 2020. @DanielGMorenaFhecor: could you do a brief review and suggest milestones for MC2020 similar to EC2 2023 in a comment below?

• [x] Review fib Model Code 2020 and create related milestones.

Here is my draft for the milestones for the package framework related to MC2020. As the MC2020 is extensive, we may need to add more sections in the future under demand.

@aperezcaldentey and @MestreCarlos , feel free to add or remove chapters if you consider it necessary.

* Next to all bullet points, I have written the respective chapter as of the last Draft of the Model Code 2020.

3a MC2020: Material properties (14 – 16)

• Concretes (14): compressive strength (14.6.1.1), tensile stress (14.6.1.2), modulus of elasticity (14.6.1.4), stress-strain relations (14.6.1.5), time effects (14.6.1.6) and temperature effects (14.6.1.7).
• Reinforcing steel (15): stress-strain relations and strength (15.10.1, 15.10.2).
• Prestressing steel (16): stress-strain relations and strength (16.1.5.3, 16.1.9.2).

3b MC2020: Ultimate Limit State (30.1)

• Bending with and without axial force (30.1.2)
• Shear (30.1.3)
• Torsion with and without axial force and/or bending (30.1.4)
• Punching (30.1.5)
• Strut-and-tie models (30.1.6)
• Compression members (30.1.7)
• Fatigue (30.2.2)

3c MC2020: Serviceability Limit State (30.5)

• Limit state of cracking (30.5.2.4)
• Limit state of deformation (30.5.2.5)
