The Obverse/Reverse Pavilion: An Example of a Form-Finding Design of Temporary, Low-Cost, and Eco-Friendly Structure

Temporary pavilions play an important role as experimental fields for architects, designers, and engineers, in addition to providing exhibition spaces. Novel structural and formal solutions applied in pavilions also can give them an unusual appearance that attracts the eyesight of spectators. In this article, the authors explore the possibility of combining structural novelty, visual attractiveness, and low cost in the design and construction of a temporary pavilion. For that purpose, an innovative structural system and design approach was applied, i.e., a membrane structure was designed in Rhino and Grasshopper environments with the use of the Kiwi!3D IsoGeometric analysis tool. The designed pavilion, named Obverse/Reverse, was built in Opole, Poland, for the occasion of World Architecture Day in July 2019. The design and the construction were performed by the authors in cooperation with students belonging to the Humanization of Urban Environment organization from the Faculty of Architecture Wroclaw University of Science and Technology. The resultant pavilion proved the potential of obtaining a low-budget but visually attractive architectural solution with the adaption of parametrical design tools and some scientific background with innovative structural systems.

Strength Analysis of Alternative Airframe Layouts of Regional Aircraft on the Basis of Automated Parametrical Models

This publication presents the results of complex parametrical strength investigations of typical wings for regional aircrafts obtained by means of the new version of the four-level algorithm (FLA) with the modified module responsible for the analysis of aerodynamic loading. This version of FLA, as well as a base one, is focused on significant decreasing time and labor input of a complex strength analysis of airframes by using simultaneously different principles of decomposition. The base version includes four-level decomposition of airframe and decomposition of strength tasks. The new one realizes additional decomposition of alternative variants of load cases during the process of determination of critical load cases. Such an algorithm is very suitable for strength analysis and designing airframes of regional aircrafts having a wide range of aerodynamic concepts. Results of validation of the new version of FLA for a high-aspect-ratio wing obtained in this work confirmed high performance of the algorithm in decreasing time and labor input of strength analysis of airframes at the preliminary stages of designing. During parametrical design investigation, some interesting results for strut-braced wings having high aspect ratios were obtained.

Parametrical design tool and the production of technical data for superadobe domes

The interest in earthbag dome construction (also known as earthbag or superadobe) has been increasing as world consciousness develops to achieve the planet’s equilibrium for sustainable living. The main objective of this research is to develop a parametric tool to help architects modeling virtual earthbag domes from ideation to construction phase. This challenge has been addressed by adopting an experimental methodology that explores parametric generative design with the use of a visual programming language (VPL). In this paper we present the development of a tool for the ideation level including features that allow for the calculation of material quantification. Even thought, the tool does not work in a Building Information Modeling environment, the generative model outputs technical information to support construction, namely material quantities. The usability of the tool was validated by a random international sample of experts.

Multi-Objective Dynamic Optimum Design of Crane Gearbox

The lower vibration and lightweight design is of great significance to large mechanical equipment. In order to achieve the best dynamic performance of cranes, this paper presents a multi-objective optimization approach based on finite element method. Firstly, the finite element model of coupling system consist of gear-rotor-bearing-housing is established. Subsequently, the transient response of the gearbox is studied using modal superposition method. Then with the purpose of reducing the vibration and preventing sympathetic resonance, a multi-objective optimizer is developed by employing a parametrical design language and obtained the optimal combination of design parameters after several iterations. The method and conclusions can be used as a reference of dynamic modification of large machineries.
