Abstract
Optimization of elastic rod systems under pulsive loading is considered for the case when the vector of variable parameters consists of two groups: geometrical parameters of sections of elements and additional nodal masses. A two-stage iterative optimization process is proposed to increase the convergence rate, including two independent optimization problems with different objective functions solved for each iteration. Optimization of a five-storey two-span steel frame under the pulse and static loads is implemented in the proposed two-stage process. The obtained results show the effectiveness of using the proposed two-stage optimization and additional nodal masses as variable parameters.
