We observed that actually the dimension of steel bars submits to efforts action is done, most of time, using computer programs or a sequence of formulas without happening an understanding of the structure behaviour. The no understanding of this behaviour difficults the aplication of the formulary or of the softwares in new and less common problems. It will be introduced, in this work, a computer program that simulates the behavior of steel pieces submited to efforts. It will be showed, through animations, the behaviour of tensioned bars, compressed bars, beams, bars subject to combined tensions and mixed beams. We intend to introduce, also,a software that monitors the dimension of steel bars submited to efforts. The program has a data bank with the formulas and necessary tables. The calculist should bring this formulas to his work surroundings, that's the page in wich he is working, and later specify the values adopted for each one of his parameters. The program controls and points out the mistakes that has been done. The software allows the calculist to use the sequence of formulas that he wants and monitors the resolution of a big number of problems.
