Our group attempted to have an
efficient structure by minimising the amount of material we were using. We
opted for a triangulated form braced from the corners to adjacent bridging
members.
The structure was rigid and held
up well to an extent. However since the joints were heavily secured, the
structure was lacking a way to transmit fluidly the forces towards the entire
structure and so with nowhere for the force to be transmitted to other members,
the skewers snapped.
Tension:
The Bracing held up to an extent.
However the make-shift pin joints wasn’t not secure enough and so the structure
was vulnerable to deformation with a simple rotation.
The bracing however worked well
and the whole structure deflected and adjusted with the simulation of the
weight test.
The pint joints allowed for slight
movement to occur and so the energy being transferred could fluidly be
dispersed around the structure and not have choke points where all the stress
was isolated in one area.
However the problem again was that
to an extent if the stress was too much, the pin joints would rotate too much
and so the whole structure would enter a twisting motion and fail
If in returning to this model, I
would secure a way to have a limit on the pin-joint rotation and hopefully
avoid the twist.
Paper:
The structure worked quite well.
The honeycomb of paper utilised the notion of going against the grain giving
more structure from materiality. As the weight was placed onto the model, the
cylinders began to deform and compress and that deformation increased the
radius of the cylinders and the whole model collectively. To counterbalance
this, the band of paper worked to contain this and so underwent tension from
physical expansion from the cylinders. These two systems worked together to
give a homogenous and well structure model.
However where the model failed was
bracing, so the overbearing weight began to tilt, the vertical structure failed
and collapsed on its side. In thinking about re-doing it, I would apply walls
or bracing support around the outside to prevent the rotating of the cylinders
