Falseworks


Most falseworks
are designed to support
vertical
loads,
but in practice
they are also subjected
to forces in the horizontal plane.

These result
from dynamic effects
such
as the rapid pouring
or vibrating of concrete,
from the movement of ten-
sioning cables,
from the wind, from differential
expansion
under heat or load,
and from many
other causes.

Some of these forces
can be estimated
but others can not,
and the fact
that they
are usually contained
is no proof
that they are not important.

They may be
particularly significant
in skew spans
where displacements in two
perpendicular directions
produce unexpected strains
in the third,
or in cases where
the design loads are applied
consecutively
rather than simultaneously.

poetry doesn't mean that you put texts in verses and hope it'll make people think. it's not that simple. yes, of course it reads differently, but there's still nothing new behind it and nothing will change that.

This was a found poem ie the poetry was already there - nothing needed to be added - it was simply reframed.

"Always be a poet, even in prose."
Charles Baudelaire
