—In concrete structures molded in situ it is
necessary to use temporary structures, called prop. These
support the actions of the permanent loads and variable as well,
while the fresh concrete becomes self-supporting. Support posts
are normally made from wood or steel. Little reuse,
deforestation and low productivity are the disadvantages of the
wood column application, against of advantage of the low cost.
On the other hand, steel column presents high productivity,
time reduces and not only high reuse but also it is renewable.
This work was carried out on the criteria design, experimental
tests and computational simulation of the steel support post.
The design criteria used in this research it’s from the Brazilian
standard. The lab tests were applied in six typical size
prototypes. And finally, for the computational simulation was
developed one specific program called FLEP. The results show
an especial care of parameter buckling in the Brazilian design
criteria and the program FLEP as well, for to obtain the same
result in experimental tests.
