• Resumen

  • This study presents an application of the response surface methodology to optimize a 5 m high concrete wall. The objective of this research work is to obtain a design solution of a concrete wall, using the CO2 emissions as an objective function to reduce its impact. To reach this objective, a factorial experimental design has been carried out to reduce the number of variables. After this, a steepest descent method has been used to look for the optimum neighborhood. Once the region around the optimum has been found, a second order response surface has been adjusted to reach the minimum. The objective function has been modified to allow a penalty for solutions that do not meet the Ultimate Limit States or stability restrictions. With this methodology, a good solution has been obtained, while also allowing the identification of the geometric design variables that mainly affect CO2 emissions.
