Abstract
The aim of the study is to develop an original, methodical, and practical approach to the early stages of parametric design of roof shells formed by repetitive modules of Catalan surfaces. It is presented on the example of designing the roof shells compound of four concrete elements. The designing process proposed by us consists in linking geometric shaping of roofs’ models with their structural analysis and optimization. Contrary to other methods, which use optimization process in order to find free roof forms, we apply it in order to explore and improve design alternatives. It is realized with the application of designing tools working in Rhinoceros 3D software. The flexible scripts elaborated by us, in order to achieve roofs’ models of regular and symmetrical shapes, are converted into simulation models to perform structural analysis. It is mainly focused on how the roof shells perform dependently on their geometric characteristics. The simulation enables one to evaluate various roof shells’ shapes, as well as to select an optimal design solution. The proposed approach to the conceptual design process may drive the designing to achieve geometric and structural forms which not only follow the design intentions but also target better results.
Highlights
The underlying compositional rules for architectural design were established by Vitruvius in TheTen Books on Architecture, in the early ages [1]
The classical architecture was determined by order and composition of forms being mostly shaped on the basis of platonic solids arranged on the Cartesian grid [2]
Thanks to Galapagos Evolutionary Solver, we have found the optimal height for each roof shell, as well as the minimal area of the Catalan surface which covers the unit area
Summary
The underlying compositional rules for architectural design were established by Vitruvius in TheTen Books on Architecture, in the early ages [1]. No linear architecture as well as organic one historically appeared in the Baroque period. This evolution of design activity understood as the process of form generating was caused by wider scientific search for theory of morphogenesis in the natural word. At first digital media were applied rather as a representation tool, soon they became the means of conceptual design. Due to this fact, the first stage of the architectural design process moved away from a traditional paper-based process consisting in 3D model creation based on the 2D drawing [4,5]. Due to widespread application of information technology tools in designing, the boundary between physical and virtual
