Two structural elements with the same moment plastic Mp subjected to the same loading
and with the same conditions of support have the same theoretical collapse load.
The present study presents a characterization for sections R.C* and R.S.C*, equivalent to
different profiles ECI. For R.C, previous work, using the characteristics adopted by two codes
(CP11O [5] and Eurocode2 [8]), were accomplisher (1.2.3). The purpose of the present study
is to achieve this characterization for the R.S.C and consolidate the work previously realized
this by using the "MATLAB version 6.5." This work has helped to consolidate and confirm
the three eaten charts.
The characterization obtained allowed to conduct a comparative study on several fronts,
concrete and ordinary concrete sand as materials and armed plain concrete and concrete sand
armed as structural elements. This comparison enables an economic study whose main
conclusion is that the structural elements in R.S.C would have a slightly higher cost than the
R.C.
