“…A criticism of all of the above systems, as Mora et al [7] point out, is that they do not look at the design problem in its entirety, although Mora et al neglect to consider building services. This lack occurs because the necessary techniques are still being developed and inevitably, given the nature of research projects and the difficulty of the challenge, they are being developed in a piecemeal fashion.…”

“…However, it must be recognised that the ideal system is one which allows all members of the design team to collaborate in the decision making process with all disciplines being given equal status. Thus the concept of Mora et al [7], where the architect makes the initial decisions and the structural system is then made to fit within this concept, is not practical because this will significantly restrict the search process. What is needed is a system where the impact of the decisions made by each design discipline is transparent so that, for example, when designers impose constraints, they are able to assess the impact of their decision on the ability of the rest of the design team to reach a good solution.…”

“…Other forms of system to support conceptual design have been proposed (e.g. [7]) but without some sort of search engine to guide the designer through the huge number of feasible options, it is difficult to see how designers will be able to find anything other than a satisficing solution, unless they are extremely lucky.…”

“…There are two fundamental approaches for zoning. One approach is that the zoning is applied with the aid of a computer design tool (Mora et al, 2004), figure 1, whereas another approach is that zoning is a part of a more or less autonomous design solution cycle (Hofmeyer et al, 2005), figure 2. The last mentioned approach can be compared with the approach of shape grammars that generate design solutions (Kotsopoulos, 2005), often used for space related problems but here applied to structural design problems.…”

Structural zoning is the recognition of forms in spatial designs. It can be used by a structural designer to develop a structural system. This paper will start with the presentation of a proof that neither user action nor a two-dimensional approach -two existing approaches of zoning-are able to recognize all possibilities for the application of a structural design to a spatial design. Only full threedimensional structural zoning is considered to be an appropriate instrument to give useful solutions. Two new concepts will be presented to overcome problems for three-dimensional zoning: (1) Geometrically Related Reducers and (2) Matrix Coupling. These concepts are first defined in a general form and thereafter the definitions are condensed into a practically applicable format. Both concepts are demonstrated when finding rectangular zones in spatial designs up to 44 separate spatial entities. They are programmed procedurally using the C++ computer language and are used for a comparison between structural designers and computer performance.

“…Interaction of spatial and structural design is not specifically defined but it is hoped that the managing of spatial and structural agents will yield interaction automatically (Fenves et al, 1994). The second project session 15: digital design methods -eCAADe 23 | proposes a methodology to synthesize structural systems within a spatial design (Mora et al, 2004). The building design process is regarded as more or less linear: the structural system follows the spatial design, however some feedback from the structural system towards the spatial design is possible.…”

During a building design process, a structural designer transforms a spatial design into a structural design and this structural system can be improved by optimisation methods or expert views of other structural designers. The improved structural system allows the architect a new spatial design, which can be transformed or altered again by the architect. This design cycle can be repeated several times and is defi ned as interaction of spatial and structural design. Case studies are used to demonstrate that this interaction occurs in practice and is needed to improve building quality. This paper presents a program with more or less autonomous spatial and structural generators. Each generator will facilitate one direction in the interaction process. Then using both consecutively leads to a design method that provides interaction between spatial and structural design. For the spatial generator, named "room positioning with structural constraints" a space allocation technique is used including constraints that handle structural boundary conditions. A zone generator based on pattern recognition and shape grammars handle the structural design. A Prolog-2 program was developed to demonstrate the application of the two proposed generators. "Zone generation" is performed per building storey and thus represents a horizontal two-dimensional procedure. Similarly "room positioning with structural constraints" is a planar vertical operation. In future these procedures can be made three-dimensional.
