Based on a case study this research aims to answer if it is possible to, automatically, materialize fire safety standards in 3D forms using algorithmic-design software and also, to analyse means, methods and requirements for its creation. First, with a short literature review it was possible to approach the concepts of BIM and parametric design as well as its use throughout design process, this review was extended to fire safety standards seeking to understand how it defines architectural details in Brazilian state of Minas Gerais. Finally, a digital tool was developed using software Windows Excel and Rhinoceros/Grasshopper, and a set simulations were made to validate its use. The study showed it is possible to achieve results similar to the ones obtained by conventional methods; therefore, the use of legal constraints as parameters on an algorithm design software may bring more flexibility to design process as it can fasten the design choices validation.

Abstract This paper describes the construction of an information flow that combines parametric modelling and genetic algorithms to optimise both the total weight of a structured steel roof and the shape of its surface to maximise the generation potential of photovoltaic energy. Through the systematisation of a design process using genetic algorithms integrated with generative design as an architectural design method, architects can work with problem parameterisation, going one step further than the mere formal proposition of solutions.As a result, we present a process in which there is a dialogical relationship between the architect and project in a continuous flow of information in the initial steps of the design process, guided by predefined optimisation objectives. Therefore, it is relevant to note that the designer accepts a reduced creative control over the final shape in favor of control over the core principles that constitute the optimisation algorithms. An approach that involved the designer in a process of post computational processing evaluations is also highlighted, giving him better support to discuss and analyze the design options.

<p>Freeform structures can provide both aesthetically interesting and material efficient solutions but are considered a demanding task for both structural design, manufacturing and architectural design. A free form surface is therefore rationalized into something more buildable like the gridshell. However, a digital design process with freeform geometry can be a complex and confusing task. By defining a gridshell as <i>nodes</i>(joints) and <i>elements</i>(members), we can set up a parametric workflow that handles the complexity in design and analysis. Optimization and rationalization of shape, topology, and cross-section are studied real-time, giving the designer confidence and design- freedom. This paper explains a parametric workflow for designing freeform gridshells. Through the design and construction of a timber gridshell pavilion with 3D printed nylon nodes, we discovered important elements of the parametric design process of freeform gridshells.</p>

<p><br clear="none"/></p><p>During the optioneering phase, engineers face the challenge of choosing between myriads of possible designs, while, simultaneously, several sorts of constraints have to be considered. We show in a case study of a 380 m long viaduct how parametric modelling can facilitate the design process. The main challenge was to satisfy the constraints imposed by several different stakeholders. In order to identify sustainable, aesthetic, economic as well as structurally efficient options, we assessed several key performance indicators in real time. By automatically estimating steel and concrete volumes, a simple, yet suitable approximation of the embodied carbon (considering 85-95%) can be obtained at a very early design stage. In summary, our parametric approach allowed us to consider a wider range of parameters and to react more flexibly to changing conditions during the project.</p><p><br clear="none"/></p>

In this study, a design methodology based on prototyping is proposed. This design methodology is intended to enhance the functionality of the test, differentiating it from the prototyping that is being conducted in conventional architectural design projects. The objective of this study is to explore reference cases that enable designers to maximize the utilization of both digital models and physical models that have been currently used in architectural designs. Also, it is to explore the complementary roles and effects of digital models and physical models. Smart Building Envelopes (SBEs) are one of challenging topics in architectural design and requires innovative design process included tests and risk management. A conceptual prototyping-based model considering the topic is applied to the design studio (education environment in university). Designing SBEs is not difficult to conceive ideas, but it is impossible to “implement” using the conventional design method. Implementing SBEs requires to strengthen validities and improve responsibilities of ideas in the stages of architectural designs, with cutting-edge technologies and smart materials. The design methodology enables designers (represented by students) to apply materials and manufacturing methods using digital models (parametric design, simulation, BIM) and physical models, rather than representing vanity images that are considered simple science fiction.

Class 1

The orthosis is considered a class 1 medical device which often originates from a nonstructured development process. As these devices are mainly developed by small- and medium-sized enterprises, with no standard research method, the result can be an unadapted device which may not respond to the user’s needs and which in the short term may be abandoned. One way to solve this problem is to define and apply standard rules and procedures throughout the development/design process. Although methodologies may solve the “empiricism” in orthosis design problems, these design strategies are not applied during orthosis development due to the particularities of this field and the difficulties in linking the required knowledge and the actors that may be present during the orthosis development. The objective of this work is to develop a methodology to structure the orthosis design process that takes into account both the device life cycle and the different stakeholders involved in the design process. A case study was used to validate the proposed methodology. It was applied to the development of an orthosis to treat a specific postural disorder called camptocormia, also known as bent spine syndrome. This disorder is characterized by the anteroflexion of the trunk and especially affects elderly people. Contrary to scoliosis, the characteristics of camptocormia are not permanent, which means that the patient is able to straighten his posture. A postural brace is used to treat this disorder which enables the patient to redress and maintain the correct upright posture of the trunk.

Mechanical products design process always focuses on the description of product structure information, while lacking of the expression and application of function and knowledge information. This paper proposes an intelligent design approach of mechanical products based on Function-Knowledge-Structure (FKS). The gene coding of function, knowledge and structure are constructed, and the correlation matrix of the Functional-Structure (FS) and Knowledge-Structure (KS) are introduced to calculate the fitness function. A case study of the conceptual design on bag forming, filling and sealing machine shows the intelligent design process based on FKS.

Main Effects

During conceptual design, designers need tools to help improve design decisions and reduce design times. We are working to develop techniques to create Bayesian surrogate models that respond to designers’ needs during conceptual stages of the design process. Bayesian surrogate models give analytical form to the overall performance of a system and can evolve along with the design. Bayesian surrogate models provide a mathematically rigorous framework in which computational models can be updated based on previous outcomes. In this paper, we present techniques that allow the addition or suppression of parameters without discarding previously obtained information. We also present a case study that illustrates how a surrogate model is constructed in stages when parameters are added or suppressed during the design process. Visualization tools, such as plots of the main effects of parameters, can be derived from surrogate models. These tools can be used to provide knowledge about the parameters that influence the design. Finally, a design problem is used to illustrate how Bayesian surrogate models can inform the designer about tradeoffs that would not be apparent from simulation data alone.
