After talking with the tutors is decided to start simple. The inspiration starts with the bridge. Further we are going to develop a way of showing mechanical formulas about displacement and strain or stress in real time. In a later phase this can be used in showing what happens with the bridge.
The first step is to make the displacement of a standard rectangular beam visible. Not only the maximum displacement but also the total displacement in a random point can be shown. All the parameters of the formulas considering the displacement are introduced.
Because the displacement normally is very small considering the height this must be shown in some proportion.
How to show this is the question. Because the displacement differs in different spans and different loads all possible input must be shown. Also the cross section is a factor that must be looked at. Further the lines of the moments, distortion in the end points and support loads can be shown in a later phase. Length of the span and measurements of the cross section of the beam can be inserted. All that is dependent from each other and this must be worked out.
It might also be possibility that the maximum displacement is known and so some other parameters, like measurements of the cross section of the beam, can be shown.
If one beam is worked out than also a floor with beams can be worked out. Also beams with other cross sections can be made. In this the area can be introduced and the number of beams carrying this. Further this can be worked out in general for the entire bridge.
The first step is to find out all about the formulas and parameters that consider the displacement of a beam. This must be shown graphically and an idea must be worked out how to show changes. Further must be found out how these changes can be made visible.
The program that I want to use is Microstation Generative Components. In this I think I have to use some scripting in creating a field for input and some fields for the numeric and graphic output.
How changes can be made and visualized:
The output is dependent from several parameters. These can be changed numeric, but the goal is to make this also possible by using a sliding bar. During the sliding of the bar it must be shown what happens. This will give a good view of what the effect of a made decision really is.
The goal is to make architectonic designs adaptable so changes in program or environment are automatically being changed in the construction. Doing this by redesigning the construction of the bridge in a generative way. (with the program generative components)
What are the basic parameters of the bridge?
- heights
- widths
- minimum or maximum spans
- area’s
What are the basic constructive demands, in constructive formula’s?
- height of construction versus span
- global loads per meter or per square meter?
How to work the bridge out?
- Listing basic elements
- putting in programmatic demands
- putting in constructive orders, for example number of columns and number of small parabolic parts.
- Introducing measurements of the constructive parts.
In a class about the program Microstation – Generative Components was told about a point related generative way of constructing. This is ideal to redesign the bridge and its construction. So the goal now is to redesign the bridge by using this method.
A first step is to find out about how the program Generative Components works.
The second step is to find out about all the relations that can be found in the bridge.
- program
- points that contact the floor
- points that contact the program borders
- mechanical needs (calculation of basic relations in order of length or height of the construction)
Put the relations into generative components.
In the class during the presentation I was told that not the program was the purpose but a design related program. In this it was advised to turn back at the bridge itself and than use all the given parametric information and possible changes for redesign the constructive parts of the bridge.
Maybe try to put in all information about basic mechanical formulas related to shape the bridge and then try to change the bridge because of a changing program or difficulties in the environment. So parametric information is used in defining the height, width and connections of the bridge.
In the class also was told that other programs are able to use parametric functions in points. Maya does have a function of using geometry that looks like a point.
During class I thought that first the design had to be looked at again. Further all forces have to be defined, per m2 or per meter. So making basic mathematical formulas that shape the form.
Rudi Stouffs said us to formulate the idea and than try to define the methodology which has to be used. It is always allowed to contact and put new information on the blog. Further the contact of the whole always has to be in thought. Initiative always has to be there.
The tutors that are helping are Andrew and Elza. Questions and how to go further has to be defined. Information about the bridge and my thoughts can be send.
After the second class some changes about the subject can be made. In general I will look at de designed bridge again. In this design I will try to figgure out a way of creating the construction again in generative components. I will look at the construction by using mechanical formulas and so trying to create a system that automatically changes the measurements of the construction if some parameters (read contact to the floor or changes in the programm) are changed. In the next days I will try to learn working with the generative component program and I have an appointment with the turors. After these steps I can tell more about the research.
This is the presentation of week 2. A suggestion for a research is introduced.
