Hi, I'm a Civil Engineering student doing my final project for my BE degree. I have developed a software that uses a genetic algorithm for optimizing reinforced concrete columns. I have tested my program with a 17 stories building, and got some very unusual results in the design but much cheaper. I would to hear some opinions regarding the feasibility of constructing this design in terms of security, if the desgin complys satisfactory with the norm (ACI) and if there would be dificulties with the conections of longitudinal reinforce between each story

The optimization is focues in lowering the overal costos, wich includs material and workload costos of concrete, reinforced and formwork.

The criteria for recycling the formwork is done for each diferent face in the column, and only if the faces are the same for two stories down. For example, the sizes of the columns for the stories 6,7,8,9 are 45x55,45x55,40x55,40x55 (cm). In this case, for the stories 8 and 9, the formwork for both parallels faces with dimension 55 cm are recycled because the 8th story uses the same two planks used in the 6th story for the faces with 55 cm, and the 9th story uses both planks of the 7th story for the faces with 55 cm. But the other faces of story 8 are not able to be recycled because story 8 has 40 cm and story 6 has 45 cm and the same happens with the 9th story.

The results are in the following link:

It is also important to note that I have worked with costs from my origin country (Bolivia), and costs of man workload are very cheap compared to material costs. Specialy steel because all steel has to be imported into the country.

Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.

send me your coding to see that and then i can tell you where you have problem.

Hi, thanks for replying. I don't have a problem in the code, I only would like to hear some comments on the design, if it is applicable in real life.
