This project aims to partially fund the visit to Brazil of Prof. Michael Faber, Department of Built Environment at Aalborg University, Denmark. Prof. Faber has an extensive list of research achievements in the areas of probabilistic modeling and analysis of systems with applications to governance and management of risks, resilience and sustainability in the built environment. Prof. Faber …
This research project aims at developing techniques for reliability-based optimization, focusing on the analysis and design of structural systems considering progressive collapse. In this context, progressive collapse is understood as the process where damage develops in a structural system from a local or individual component and propagates to the rest of the structure, resulting into a …
Structural engineering design should be robust w.r.t. the uncertainties inherently present in loads, material strengths and engineering models. This perception has led to the concept of Reliability Based Design Optimization or RBDO, where design constraints are written in terms of minimal reliability levels. A literature review reveals that most papers addressing this subject replace dete…

The following project aims to study the optimal design under uncertainties of truss systems considering the progressive collapse. This phenomenon has raised engineers' and researchers' awareness in recent years. In general, the causes of progressive collapse in structures are related to the existence of uncertainties, which are classified as aleatory and epistemic. In this context, optimi…
This research proposal intends to find an optimal design of structures subjected to seismic actions, through the methodology of Probabilistic-Based Earthquake Engineering (PBEE) and Risk Optimization (RO). Brazil, based on its geographic location inside a tectonic plate, had for many years its structures built with no consideration regarding seismic events. Brazilian standard for seismic …
Currently, the usual project design is made member by member and in a semi probabilistic way, using partial safety factors calibrated to lead to the target reliability. Redundancy, typical of hyperstatic structural systems, is not objectively accounted in the design. However, recent occurrences of partial and global progressive collapse have instigated the designers to consider the system…
This research project aims at proposing a formulation for topology optimization of manufacturing tolerant compliant mechanisms which respect a stress failure criterion. The proposed formulation follows the three-field density approach developed in Sigmund (2009) and Wang et al. (2011), first proposed for the design of manufacturing tolerant continuum structures. The novelty in this propos…
Results of structural optimization should be robust with respect to the uncertainties inherent to strength of materials and structural actions. This observation has led to the development of diferente methodologies for structural optimization under uncertainties: stochastic or robust optimization, fuzzy optimization, reliability-based optimization and risk optimization. However, a review …

The design of reinforced concrete (RC) frames considering progressive collapse is a complex problem due to the large impact of element removal on structural loads, hence also on strengthening costs, in spite of its low probability of occurrence. The candidate and his supervisor in Brazil are pioneering the development of novel reliability-based cost-benefit analysis for such designs, as d…
This research project aims at proposing a topology optimization framework to solve high resolution 3D topology optimization problems considering local stress constraints and manufacturing uncertainties. In order to achieve such a goal, the stress-constrained formulation presented in Da Silva, Beck and Sigmund (2019) is employed, which follows the three-field density approach developed in …
