Manolis Papadrakakis, Nikos D. Lagaros

The paper examines the efficiency of soft computing techniques in structural optimization, in particular algorithms based on evolution strategies combined with neural networks, for solving...

Recent advances in reliability-based structural optimization under earthquake loading (2005)

Yiannis Tsompanakis, Nikos D. Lagaros, Michalis Fragiadakis, Manolis Papadrakakis

In this paper a robust and efficient methodology is presented for treating large-scale reliability-based, structural optimization problems under seismic loads using the pushover analysis method. The...

Structural design in the framework of cascade evolutionary optimization (2005)

Nikos D. Lagaros, Dimos C. Charmpis, Yiannis Tsompanakis, Manolis Papadrakakis

In structural sizing optimization problems the aim is to minimize an objective function under certain constraints. The design variables of the optimization problem are generally discrete and belong...

Multi-performance robust optimum design of steel structures (2005)

Nikos D. Lagaros, Vagelis Plevris, Yiannis Tsompanakis, Manolis Papadrakakis

In engineering problems the randomness and uncertainties are inherent, thus the scatter of structural parameters from their nominal ideal values is unavoidable. Robust Design Optimization (RDO)...

Multi-objective optimization of skeletal structures under static and seismic loading conditions (2002)

Manolis Papadrakakis, Nikos D. Lagaros, Vagelis Plevris

Almost every real world problem involves simultaneous optimization of several incommensurable and often competing objectives which constitutes a multi-objective optimization problem. In...

Abstract Reliability-based structural optimization using (2002)

Neural Networks, Monte Carlo Simulation, Manolis Papadrakakis, Nikos D. Lagaros

paper examines the application of neural networks (NN) to reliability-based structural optimization of largescale structural systems. The failure of the structural system is associated with the...
