Proportional Topology Optimization under Reliability-based Constraints [PDF]
Journal of Applied and Computational Mechanics, 2022 Topology optimization is a methodology widely used in the design phase that has gained space in engineering. On the other hand, uncertainty is present in material properties, loads, and boundary conditions in practically any design.

Robust and reliability-based design optimization of steel beams [PDF]
Archives of Civil Engineering, 2023 In line with the principles of modern design a building structure should not only be safe but also optimized. In deterministic optimization, the uncertainties of the structures are not explicitly taken into account.

Optimal reliability-based code calibration [PDF]
Structural Safety, 1994 Calibration of partial safety factors is considered in general, including classes of structures where no code exists beforehand. The partial safety factors are determined such that the difference between the reliability for the different structures in the class considered and a target reliability level is minimized.
