Tools for analysis of reinforced concrete sections

Hi there 👋

conctools's Issues

Embed a small cross section plot to capacity diagram

Description

Add an option for plotting a small version of the cross section in the same figure as the interaction diagram.
This could be useful to avoid having to plot the the cross section geometry in a separate figure.

Add coverage bagde to README

Add a badge to README showing the percentage of code that is covered by tests.

Include examples in docs and readme

Description

Include examples of hos to create a cross section and plot interaction diagrams. Both in the documentation and in the readme.

Ease rebar modelling of slabs

Description

Make it easy to generate reinforcement based on diameter and spacing for rectangular slab sections. A slab in this sense means that the cover at the sides is 0mm.

Something like:

# Pseudo input
rebar_input = ['layer1: 32s150', 'layer2: 25/150']

# Section creation
Section(b, h, rebars=rebar_input)

• Both formats 32s150 and 25/150 should be supported
• Cover to rebar layer should be input as well

At first, it would be reasonable to have this for rectangular sections, where it is most useful.

Limitations

When given a rebar size with spacing, the exact locations of rebars are not known. Thus, a rebar layer should be represented as a smeared out line with equivalent properties for bending about the horizontal axis.

Only uniaxial bending is allowed for such a section, since the distance from the neutral axis to the rebar layer "line" is always known then. If the neutral axis rotates, the distance to each bar becomes a problem to evaluate (might be doable with some tricks though)

Note: Biaxial bending is a long way from being implemented, so probably not a concern
