Optimal Whole-Llife-Cycle Seismic Design of Concrete Frames
Abstract eng: In this study multi-objective optimization of structural frames is investigated. Two different materials, reinforced concrete and reinforced engineered cementitious composites (ECC), with different response characteristics are used to model the frames. ECC is characterized by high tensile strength and ductility, high energy absorption and reduced crack widths when compared to conventional concrete. However, the material is more expensive than conventional concrete. Therefore, in order to quantify the potential benefits that could be obtained by replacing concrete with ECC, the structural performance is evaluated for the whole-life-cycle of the structure. The results of the optimization problem are presented in Pareto-optimal form which is preferred by decision makers due to the provided flexibility in selecting the solution alternatives. The option of replacing the conventional material, concrete, with a high performance alternative, ECC, is investigated in an optimization framework with the ultimate goal of higher safety, increased sustainability and improved performance.
