project G:Gerry Hobbelman
Meeting with Gerry Hobbelman
Structural engineer
14-12-2011
First we explained the project to Gerry Hobbelman after which he already was very interested.
He refered to a project the faculty was thinking of themselves. In this project elements came out of the floor to form walls. The whole project was meant to be able to test out out different lay outs of space.
On the structure:
In principle the design is possible and with the wright materials stabile.
To get to know the forces he gave us some basic calculations:
N*z=m
N=m/z
N = the pulling or pushing force on the side of the box (bottom pulling, top pushing)
Z = The distance between the highest point where the boxes touch and, the lowest point where the boxes are kept together.
M = Moment which excist in a ‘beam’ of boxes
The beam or cantilever is the most challenging set up which the boxes can reach (with the biggest moment)
With a big difference between boxes the Z becomes small so the pulling and pushing forces become bigger.
To make the Z as big as possible we should connect the boxes at the lowest and highest possible point with an element free of movement. this will also prevent a lot over bending moment in the threat.
He also mentioned the telescope arm to fix the intervention when it doesn’t need to move. This will help with load bearing but more important it becomes more stabile.
The connection between the two boxes should have a bit more height and stifness
Finally we need to support the threats to coop with the weight they need to carry under pressure circumstances.
