Optimum Analysis of Damper Braces Based on Genetic Algorithm

The aims at optimization of structure with damper braces is studied in this paper.The sum of damping coefficient of all damper braces is considered as a goal function,and the storey displacements are considered as constraint conditions.The program,which introduces the non-proportional damp matrix,based on genetic algorithm and time history is used to analyze the optimization of a damper braced frame.The results are reasonable and show that the genetic algorithm is an efficient method to optimize the damper braced structure.
