# Wall reinforcement

Hello!

I would like to kindly ask for your help with automatization of wall reinfrocement made in grasshopper and linked to tekla. Let me shortly describe what I would like to achive.

I have a concrete wall in tekla made as a panel together with few openings made as polygon cutouts.
This is just an example- there could be less/more openings with different size.

I would like to crate automatic reinforcement that will adjust when location or size of the openings will change. Reinforcement must be placed as “Equal distribution by target spacing value” since this value is shown on the drawing.
I need to create some reinforcement around openings like on the screen but I already figure it that I need to get children from main part then find points and finaly create reinforcement.

From this point I have no idea how to handle rest of horizontal and vertical reinforcement. My idea is to consider it as 2 separate aspects.
Vertical reinforcement:
Since I already have some vertical bars from the openings I would like to use them and divide wall to some “zones” where I will put rebar groups. To find vertical boundaries I will just find all X points of openings and sort them. However, I am not sure how to place 2 separate rebar groups for example in zone 4 and 5 or 7 and 8.

Horizontal reinforcement:
Assuming that vertical reinfrocement will be solved I am facing a problem how to handle horizontal reinforcement. Basic assumption is that I am placing horizontal reinforcement from bottom to top with equal spacing and then I would like to divide it somehow considering openings. In fact wall should be divided in another “zones”- horizontal this time. Unfortunatelly, I have no idea how to handle that because I would have to crate seperate bar groups with traget spacing value. I know that I can calculate exact spacing and then theoreticaly maneuver with insertion point at Z axis, however I do not know hot to handle zones where bars are for example between windows only.

After that there are some other challanges I need to face but first of all I would like to focus to solv this issue.

I would appreciate every single comment and help to solve this puzzle. Maybe my approach is totaly wrong and it can be done in different way!

Hi Arek,

Here I would perhaps try with Tekla components rather than doing rebar groups. E.g. Wall panel Reinforcement, Mesh bars, Hole reinforcement etc. You can insert them from Grasshopper as well.

Or then rebar sets would probably work well in this scenario - those aren’t available in Grasshopper at this point though, but we’re hoping to add them at some point. But even used manually they can be quite fast and adaptive.

Cheers,

Sebastian

Hi Sebastian

I already tried few components (even some other downloaded from warehouse) but none of them fit to my specific requirements that is why I would like to create my own component. Nevertheless, I will try to use figure it out.

there are good tutorials with the tekla connection like this Tutorial

Also there are some webinars from the Youtuber Learn Grasshopper but there getting quite complex. This should fit to your needs i think.

Navigating the intricacies of automatic reinforcement in Grasshopper for Tekla integration is challenging. Consider dividing the wall into zones for vertical bars and calculate spacing for horizontal bars, addressing unique challenges in each zone.
