INSPIRATION

Date: September 26th. 11:30 – 13:30.

Workshop given by:

Tullia Iori
Università di Roma Tor Vergata

Description:

There are different approaches to designing a structure.

For example, there is a “naturalistic” approach: it is based on the idea of imitating nature, of finding in the forms existing in nature for the minimum one, the perfect one.

Then, instead, there is an approach that, given a rationally compatible solution, tries to improve it by adding loads that balance others, balancing forces, compensating stresses, correcting nature.

In the workshop we will see how these two approaches have been interpreted in the Italian School of Engineering: in particular, by Pier Luigi Nervi, Riccardo Morandi, Silvano Zorzi, Sergio Musmeci. And we will see how these approaches are still relevant and valid for the future of structural engineering.

DATA COLLECTION

Date: September 26th. 16:30 – 18:30.

Workshop given by:

Julián Moreno

Description:

Currently, the works for surveying and following up the evolution of structural pathologies of concrete structures are carried out employing digital cameras from the ground level or scaffoldings. When we face the characterisation of surfaces of dams, cooling towers, bridges or big vertical structures, many times depend on companies of work at height, having the structuralist to accept to carry out his work with the pictures provided by them, without having the chance to neither measure them, nor seeing them by himself.

Additionally, when it is about of following up the evolution of structural pathologies, we find it is not easy, since traditional photography does not support a valid dimensional characterisation. Sometimes, it can be draw on installing gauges, but it is not a simple methodology, due to the access difficulty or even hazardousness of the place where many times the pathology is located.

In this workshop we will describe how, by using drones and a technology developed by Hemav based on direct-orientation photogrammetry, it is possible to carry out photographic characterisation of concrete pathologies, including dimensional information and directly capturing their location, allowing the structuralist to easily obtain damage maps and to trace its evolution.

Description:

The “Monitoring, Big Data, Artificial Intelligence and Diagnostic” workshop aims to illustrate the key breakthroughs and the emerging challenges related to the structural health monitoring systems. It is also intended to discuss how the smart SHM technologies can be used to understand the evolution of structural behaviour with time and detect possible damages, with a view to improving safety and maintenance based on a large-scale data sets.

The workshop will consist of two main parts.

The first part will show a framework for the safety evaluation of critical civil infrastructures, such as tunnels and bridges, through a reliable monitoring system based on MEMS clinometers. In particular, data elaboration techniques will be illustrated, in order to underline the importance of cleansing data coming from sensors before process them. A number of case studies will be presented; thresholds evaluation will be also illustrated based on the total variation of the monitored parameters with respect to the expected ones.

The second section will describe the application of MEMS accelerometers in a high performance and cost-effective SHM system for bridge structures. The focus will be on the “Big Data” challenge that is the possibility to collect a huge amount of data and find a way to properly process and manage them, in order to find significant parameters able to synthesize the most relevant information. Results from a real time monitoring system installed in a box section composite highway bridge will be presented and discussed.

The workshop will include also some interactive activities in which attendees become active participants who contribute to the outcome.

Workshop given by:

Sarai Zaballa

Francisco Tabanera
Modelical, Spain

Description:

The aim of this workshop is to introduce to the attendees to the thorough use of point-clouds as the basis for existing conditions modelling of structures. Working with  point-clouds poses several challenges that are not generally well understood among the structural design community: physical survey, point-cloud processing and registration, evaluation, rationalisation and modelling, each step requires careful planning and the use of a mix of tools that include geometry workbenches -Rhinoceros in our case- and BIM environments -Revit- with statistical analysis and scripting environments -Grasshopper and Dynamo.

The workshop will illustrate, through a case study, the general approach, key parameters and techniques required to obtain a useful structural model from a point-cloud, based on our experiences in extreme projects like Santiago Bernabeu Stadium or Sagrada Familia. First we will cover the different gathering techniques that include laser scans, land-based photogrammetry and drone and aerial imaging, and will show how each system applies to each purpose. Then we will present the different processing approaches that are required to obtain the base point-cloud. Next we will explain how to use the point-cloud as a reference for modelling, either directly or by means of mathematical analysis, and will reflect on the decisions the engineer needs to take in order to ensure a useful and lean model that is fit for design purposes.

The workshop will be taught in the form of an instructional demo, with examples supporting all the key contents, but participants are encouraged to follow the contents with their computers.

CREATIVITY

Date: September 27th. 11:30 – 13:30.

Workshop given by:

Clemens Preisinger
Bollinger + Grohmann, Austria

Description:

As an introduction to the topic the attendees will be presented projects done in the structural engineering office of Bollinger + Grohmann which showcase the integration of parametrically defined geometries and structural analysis via Karamba3D, a plug-in for Grasshopper for Rhinoceros. A basic introduction into the usage and capabilities of Karamba3D forms the main part of the workshop. Pre-assembled definitions serve as the basis for discussing typical use-cases and different styles of user-interaction. During a hands-on section the attendees get the opportunity to try out the presented techniques.

In order to get the most out of this workshop attendees are asked to install Rhino6 and the current version of Karamba3D on their Laptops and bring them along. For Rhino6 the Trial-version is sufficient. Licenses for Karamba3D will be sent to the attendees prior to the workshop. In order to follow the workshop no prior scripting experiences in Grasshopper are required.

Date: September 27th. 11:30 – 13:30.

Workshop given by:

Description:

The aim of this workshop is to introduce the participants to a novel design method for the generation of equilibrated structures in three-dimensions using graphic statics and specifically the Combinatorial Equilibrium Modelling (CEM). CEM is an innovative approach to structural design in which, contrary to other equilibrium-based form finding approaches (such as particle-spring systems, force density method and dynamic relaxation), the equilibrium condition is inherent to the model and does not require any numerical simulation to be computed. CEM is grounded on vector-based 3D graphic statics and graph theory and allows the designers to take full advantage of the relationship between topology, form and structural behavior during the early stages of the design process. To make this approach operative, an interactive, computer-aided design tool has been developed within the 3D software environment McNeel Rhinoceros and Grasshopper. The tool enables the designers to work in real-time and in an intuitive way to generate non-conventional 3D spatial networks in equilibrium (form diagram) for any designer-specified connectivity, any combination of compression and tension forces (topological diagram) and any set of force magnitudes (force diagram).

The workshop consists of two halves: a taught part discussing principles and containing simple exercises and demonstrations; a second part where a couple of relevant case studies developed using the CEM will be presented to the participants.

Date: September 27th. 11:30 – 13:30.

Description:

The search for structural efficiency and material optimization has been a constant source of inspiration in structural engineering. Historically motivated as a material necessity, a number of efficient designs tailored to the potential of the structural materials have been developed in the past, notably within the 20th century. In many cases, relying on simple calculations (mostly based on equilibrium considerations) and with a sound structural concept and detailing, true masterworks were constructed. 

In this contribution, it is explored the process of the conceptual design of structures. This process is shown following a case-based approach where selected projects are analysed. It is shown the significance of the analysis by means of simple equilibrium-based approaches and the necessity to consider the site specifications. A special emphasis is dedicated to the evolution of the conceptual design and how even radical changes are eventually required to satisfy the project constraints that may evolve during the project or construction phases.

Description:

Nowadays we live in a society where any product needs to be visually attractive to be consumed. The realm of engineering and architecture are not an exception since the aesthetic component is as equal or even more important than functionality or technique. The appearance definitely sells itself, and our industry needs buyers.

Renders and other digital techniques are the tools for translating projects from the abstract sphere, where they have been elaborated, to an emotional and visual level where they will connect with the consumer.

During this workshop, we will go inside the kitchen to see how a render is made by analyzing different stages of the process: Image approach, modeling, camera selection, lighting and postproduction. We will also show several examples of architectural visualizations and will take a close look at the relation and workflow with the client.

Date: September 27th. 16:30 – 18:30.
