“…The interrelation between shape, material, and behavior of structures found in Nature becomes a base of new methods of optimization. Biomimetic inspirations are the main factor of the designing process, where the properties of selected materials, structural behavior as well as manufacturing technologies influence the early stage of designing and, therefore, the structural optimization process [10] [11]. The integration of tools that help to optimize the construction process under human-machine collaboration is continuously invented [12].…”

Trends in contemporary architecture are constantly changing the quality of engineering solutions through broadly understood optimization. The designers, as never before, are facing the possibility to adjust the material and manufacturing technology to desired aesthetic outcomes, by not only the material usage but also the self-organization of the optimization of the structure. The development of modern computational software and the ability to modeling structural forms in non-Euclidean geometry while using algorithms lead designers to new fields of designing and constructing. Parameterization of modeling tools and processes caused an increase in interest in bionic and biomimetic inspirations. It is expressed by imitation of the structure and behavior of living organisms. Such actions enabled the implementation of ideas as forms follow energy and forms follow forces. Analysis of the morphology of structural forms as well as generative modeling based on logical patterns taken from Nature are one of the contemporary tools of designing. Nowadays, the development of building technologies is strongly supported by digital techniques of manufacturing building elements, which has a significant impact on the architectural detail shaping. Geometrically complex forms are generated as non-modular elements; due to the rapid growth of digital fabrication (components with different shapes are made individually-cut out by CNC machine tools, printed, cast). with outstanding precision). A vital element of new technologies development is the search for new materials and the improvement of manufacturing methods at the same time. The article presents new tools and methods for the optimization of structural elements on selected examples.

Computational manufacturing technologies such as 3D printing hold the potential for creating objects with previously undreamed‐of combinations of functionality and physical properties. Human designers, however, typically cannot exploit the full geometric (and often material) complexity of which these devices are capable. This STAR examines recent systems developed by the computer graphics community in which designers specify higher‐level goals ranging from structural integrity and deformation to appearance and aesthetics, with the final detailed shape and manufacturing instructions emerging as the result of computation. It summarizes frameworks for interaction, simulation, and optimization, as well as documents the range of general objectives and domain‐specific goals that have been considered. An important unifying thread in this analysis is that different underlying geometric and physical representations are necessary for different tasks: we document over a dozen classes of representations that have been used for fabrication‐aware design in the literature. We analyze how these classes possess obvious advantages for some needs, but have also been used in creative manners to facilitate unexpected problem solutions.

“…Long-spanned free-form roofs and building skins are realized as grid shells connecting a set of discrete (opaque or transparent) panels to a supporting grid structure. Before the structural aspects, the engineering process of the geometrical and constructional definition of the facetted architectural shape is related to the feasibility and the modalities of the base-surface subdivision (Adriaenssens et al Adriaenssens et al 2012Baldassini et al 2010;Pottmann 2013;Pottmann et al 2007;Sassone and Pugnale 2010).…”

Grid shells supporting transparent or opaque panels are largely used to cover long-spanned spaces because of their lightness, the easy setup, and economy. This paper presents the results of experimental static and dynamic investigations carried out on a large-scale freeform grid shell mock-up, whose geometry descended from an innovative Voronoi polygonal pattern. Accompanying finite-element method (FEM) simulations followed. To these purposes, a four-step procedure was adopted: (1) a perfect FEM model was analyzed; (2) using the modal shapes scaled by measuring the mock-up, a deformed unloaded geometry was built, which took into account the defects caused by the assembly phase; (3) experimental static tests were executed by affixing weights to the mockup, and a simplified representative FEM model was calibrated, choosing the nodes stiffness and the material properties as parameters; and (4) modal identification was performed through operational modal analysis and impulsive tests, and then, a simplified FEM dynamical model was calibrated. Due to the high deformability of the mockup, only a symmetric load case configuration was adopted
