deFining OptimizatiOn the

Fitness criteria and gens

The multi-objects optimization in this project done using Wallacei. Wallacei is an Evolutionary multi-Objective optimization and analytic engine for Grasshopper3D. This tools use the Non-dominat Sorting Genetic Algorithm (NSGAII) for performing multi-object optimizations.

Gens

The Multi-object Optimization problem has been run regarding each model seismic performance.The seismic performance indicators including drift and lateral displacement (Dis)as the indicators of measuring the vulnerability of NSCs and the overturning moment(OvM) and weight per unit area of the structure(Wsqr) as the indicator of the optimal structural design of tall buildings.
