Timber gridshells: beyond the drawing board

In March 2011, a week-long workshop that invited participation from all architecture and architectural technology students at Sheffield Hallam University, UK was organised with the objective of enhancing students’ thinking and experience by construction thinking. It was aimed at creating a sense of realness to realise a design project collectively. Timber was set as the material of exploration. The students had to make use of bending to design and create a timber gridshell structure. This made use of a quality traditionally felt to be a structural weakness of the material. To do this, students form-found non-mathematically and non-digitally using paper gridmats. This paper describes the aims, activity and outcome of the timber gridshell workshop as a way of preparing architects and technologists of the future and introducing the challenges of architectural design in terms of economics and construction process, aesthetics, effective communication and structural intuition by working with a given material – all important aspects in achieving effective architecture

An overview of historical and contemporary concrete shells, their construction and factors in their general disappearance

Only through understanding why concrete shells’ loss in popularity over the course of modern history can designers be equipped with the skills to create and apply this type of construction. Through modifications to design processes, construction stages, material understanding and relevant formwork improvements will architects and designers be able to meet the demands of the 21st century and beyond. To understand why concrete shells are no longer commonly built is to understand its construction process. An amorphous material, the fundamental relationship between formwork and the resultant concrete shell needs to be raised, appreciated, understood and analyzed for a holistic understanding of concrete shells. Through understanding this, issues and factors affecting concrete shells can be tackled and designed out in reviving this type of structures because they can be efficient in structural performance, economical in cost and provide high aesthetic value. This paper discusses concrete shells as an architectural solution by asking the question to what constituted their popularity and factors that led to their demise in the modern age of technological advancement, construction process and environmental concerns. This paper presents a cultural perspective and an overview of seminal, historical and contemporary concrete shells so as to bring about a renaissance of such structures in our built environment once again because of all the benefits it can offer.</p

Structural Engineering Heroes and their Inspirational Journey

[EN] In the nineteenth century, civil and structural engineers received much public acclaim for their built works (e.g. Brooklyn Bridge, Eiffel Tower). One hundred years later, the engineer was perceived by many as "out" or as not requiring much skill. This paper examines how this erroneous perception of structural engineering can change by presenting structural engineers as heroes. Using parallels to the monomythical hero, and examples of engineers, the authors present the journey and characteristics of the structural engineering hero. The journey, which has many paths, begins with the engineer leaving the comfortable "Ordinary World" of design into a "Special World", where new forms, new materials, and/or scale for projects is needed. For underrepresented groups of people such as women and minorities, the heroic journey could be simply becoming an engineer and developing a career in conditions of equality and equity. As structural engineering heroes enter the Special World, they may face trials of nature and criticism, and face constraints of economy, time and knowledge. In the final Act of the journey, they return to the Ordinary World wiser, disseminating their knowledge and inspiring others. The authors define the characteristics of structural engineering heroes by four "P"s: they are prepared, they are planners, they have (super) powers and they are persona grata. The education of the structural engineer should train and inspire future engineers using the lessons learned from the heroes and their diversity. By doing so, what seems exceptional today can become common in the future.Paya-Zaforteza, I.; Garlock, MEM. (2021). Structural Engineering Heroes and their Inspirational Journey.

Environmental, economic, and social sustainability in aquaculture: the aquaculture performance indicators

Aquaculture is a rapidly growing food production technology, but there are significant concerns related to its environmental impact and adverse social effects. We examine aquaculture outcomes in a three pillars of sustainability framework by analyzing data collected using the Aquaculture Performance Indicators. Using this approach, comparable data has been collected for 57 aquaculture systems worldwide on 88 metrics that measure social, economic, or environmental outcomes. We first examine the relationships among the three pillars of sustainability and then analyze performance in the three pillars by technology and species. The results show that economic, social, and environmental outcomes are, on average, mutually reinforced in global aquaculture systems. However, the analysis also shows significant variation in the degree of sustainability in different aquaculture systems, and weak performance of some production systems in some dimensions provides opportunity for innovative policy measures and investment to further align sustainability objectives.Taryn Garlock has received financial support from NIFA Hatch Project #7006413, and Frank Asche has received financial support from NIFA Hatch Project #7004716.
