Abstract:

The use of computational methods and tools for analysis, safety assessment and retrofitting of existing structures is becoming increasingly important in intervention planning (e.g., maintenance, repair, rehabilitation, strengthening). Nonetheless the state of development of the computational methods and numerical tools, there are still many uncertainties and difficulties in their use in the assessment of existing buildings and bridges. Actually, worldwide there is an increasing attention to the safety assessment and improvement of existing structures and infrastructures, due to their state of conservation and safety. New strengthening materials and techniques are emerging. Also, new structural codes are being proposed with different approaches and demand requirements, particularly with focus on the assessment and retrofitting. Robust and liable numerical modelling tools have to be developed, validated and calibrated to be adopted into practice, guiding the designer to adopt optimum sustainable solutions in terms of cost and efficiency, respecting the original values of the construction.
In this context, the mini-symposium aims to attract academics, researchers, postgraduate students and professional engineers who deal with the development and application of computational methods in support to the safety assessment and retrofitting of existing structures of any type (heritage or modern; buildings, bridges or other), adopting innovative materials and design concepts. In the mini-symposium are expected contributions in terms of development and application of models, and numerical strategies, in the assessment and design of repair and retrofitting. Presentation of case studies and applications using numerical modelling in support to retrofitting interventions are also of particular interest.

Abstract:

Structural design should be robust with respect to uncertainties inherently present in resistance of structural materials, environmental and man‐imposed loads, boundary conditions, physical, mathematical and numerical models, and generally to different types of intrinsic and epistemic uncertainties. Structural performance and reliability should be robust against unexpected fluctuations or changes in problem parameters. Proper decision making in presence of uncertainties is fundamental to avoid severe or fatal consequences and/or costly posteriori changes over the built structure. These issues have led to the recent development of structural reliability methods and reliability‐based optimization. This mini‐ symposium aims at bringing together researchers, academics and practicing engineers concerned with the various forms of structural reliability analysis and structural optimization in presence of uncertainties. Contributions addressing both theoretical developments and practical applications, in the following topics, are invited:

  • Structural reliability methods (FORM, SORM, Monte Carlo Simulation);
  • Applications of structural reliability to challenging engineering problems;
  • Robust structural optimization;
  • Performance‐based optimization;
  • Reliability‐based structural optimization;

  • Modeling of extreme or rare events;
  • Decision‐making in presence of uncertainties;
  • Modeling of uncertainty with probability theory, Bayesian theory, imprecise probabilities including evidence theory, interval models, fuzzy set theory, information gap theory, etc.
  • Structural health monitoring,system identification and damage detection.
  • Development and application of surrogate models for uncertainty quantification and structural optimization.

Abstract:

The wave approach in structural dynamics focus on local properties such as the dispersion relations, phase and group velocities, waves modes and energy transmission. This is in contrast to the modal approach, which typically focus in global properties such as the natural frequencies and modes shapes. Experimental technics for modal analysis are well stablished and have been successfully applied in the past decades unlike the experimental approaches for wave propagation. This paper aims to investigate experimental approaches for the identification of the wavenumber in light weight strucutres undergoing flexural vibration. The underlying experimental setup consists of measuring frequency response functions by impact hammer or shaker excitation at evenly spaced points. Different estimation techniques are used, such as the Inhomogeneous Wave Correlation (IWC) and Discrete Fourier Transform (DFT) based approaches and the influence of measurement points distance, positioning along the structures are investigated. The IWC approach estimates a wavenumber at each frequency in which the measurements presents a maximum correlation with a prescribed wavefiled. DFT-based approaches rely on the concept of spatial frequency of the Operational Deflection Shaped (ODS), obtained from the FRF measurements in a regularly spaced grid. The wavenumbers are estimated by the dominant components in the DFT wavenumber spectrum . Upper and lower limits of the frequency bands for the analysis are given for light weigth structures such as honeycomb sandwiche panel, for aerospace applications, and metamaterial beams produced from additive manufacturing with locally resonant band gaps. Results are compared to an available analytical and numerical solutions show good agreement.

Abstract:

Established engineering works and projects show us that architecture and structure projects must be conceived and developed together. Despite this, what we normally see is a relation of distance between these two elements of civil construction. This mini-symposium aims to bring together the two fields of knowledge and show that the design of the structural system plays an essential role in determining the architectural design. Projects that explore the relationship between architecture and structure and the direct relationship between form and structure, where the definition of the structural system has effective participation since the design of the projects, provide works marked by structural boldness and major technological challenges. The mini symposium aims to gather contributions and obtain data that, through analyzes that use computational technologies and numerical methods, allow us to understand how the structural design allied to architectural creation provide innovative aesthetic results. Through these studies, it is possible to emphasize the importance of the technical knowledge for the realization of projects of good quality, evidencing the presence of the structural system in the architectural form. These analyzes contribute to the understanding of the importance of technical and technological knowledge for the production of an innovative architecture.

Resumo:

Grandes e consagradas obras nos mostram que os projetos de arquitetura e estrutura devem ser concebidas e se desenvolver juntos. Apesar disso, o que se vê normalmente é uma relação de afastamento entre esses dois elementos da construção civil. Esse mini simpósio visa aproximar os dois campos do conhecimento e mostrar que o projeto do sistema estrutural tem um papel essencial na determinação do desenho arquitetônico. Projetos que exploram a relação arquitetura-estrutura e a relação direta entre forma e estrutura, onde a definição do sistema estrutural tem participação efetiva desde a concepção dos projetos, proporcionam obras marcadas pelo arrojo estrutural e por grandes desafios tecnológicos. O mini simpósio tem como objetivo, reunir contribuições e obter dados que, por meio de análises que utilizam tecnologias computacionais e métodos numéricos, permitam entender como a concepção estrutural aliada à criação arquitetônica proporcionam resultados estéticos inovadores. Por meio desses estudos é possível destacar a importância do conhecimento técnico para a realização de projetos de boa qualidade, evidenciando a presença do sistema estrutural na forma arquitetônica. Essas análises contribuem para o entendimento da importância do conhecimento técnico e tecnológico para a produção de uma arquitetura inovadora.

Advances on the Design and Optimization of Membranes, Gridshells and Bending-active Structures

Ruy Marcelo de Oliveira Pauletti, Associate Professor, Polytechnic School at the University of São Paulo, +55.11.3091.5588 / +55.11.99118.5914, pauletti@usp.br

Abstract:

Light structures such as cables net, tensegrities, membranes, pneumatics, gridshells and bending-active structures contribute to reduce the material consumption, the need for scaffoldings, the time-span for construction and the required labor time. Thus, they allow reducing the overall energy embedded in buildings and their environmental footprint. However, to achieve this potential, these structures require a thorough design, including shape-finding and optimization methods as well as nonlinear structural analysis, under complex load cases, such as wind pressures on highly flexible, free-form structures. In recent years, advances in computational methods for shape finding, fluid-structure interaction and parametric modelling and optimization allow designers to explore a much broader design space, achieving structurally efficient and formally remarkable buildings. These session aims to review the advances on the field, providing a forum for the exchange of new ideas and concepts among researchers.

Abstract:

Evaporates are economically important because they are sources of raw material for the manufacture of various products. Silvita, for example, is the most exploited mineral for the production of potassium, because its chemical structure of chloride simply favors its industrial use. In addition evaporites are sealing rocks par excellence serving for storage of natural gas and toxic waste among other uses. Analyzes of stabilities and deformation of cavities in evaporites are thus extremely important allied to analyzes of laboratory tests in salt rock. This mini symposium aims to bring together both fields of knowledge, both field-scale and laboratory studies, and show that previous studies of evaporites in salt-pumping projects, gas storage, oil wells and others can contribute in a positive and effective way in reducing costs and increasing security stability. The mini symposium aims to gather contributions and obtain data that through analyzes using computational technologies, numerical methods and mathematical models allow to understand how the evaporites behave, as an example, thermo-mechanical and chemical, in a coupled or do not.
