Problem statement: Self-organizing particles in nature have long inspired structural form-findings. These forms shaped to transfer forces efficiently use minimal materials and are light-weight. Physical models have been used to explore these self-organizing particles and served as a basis for design and calculation. However, making, measuring, and scaling these models is tedious and hard, especially for complex geometries such as tree-like structures. Nowadays, computer simulations can apply nature’s logic to create digital models. These models simulate form-finding and scaling faster and easier.Research

The purpose of this research is to present a digital tool derived from algorithmic design for the digital form finding of branching structures based on the physical testing of a wet thread model.Research

This research was first formed through the study of available resources and scientific articles in this field, and then the results were used to design digital tools using computational methods.

Algorithmic design based on the wet thread model simplifies the optimal design of tree-like structures. It optimizes both the design outcome and the design process. Physical form-finding often faces difficulties in converting models into construction plans. By digitizing this process, the measurement of the final form becomes faster and easier. This enhances the constructability of these forms.

Today, smart cities are a new paradigm in the global urban planning system. Based on the capabilities of information and communication technology, these smart cities try to improve the quality of life in places which are immersed in numerous problems with social, economic, environmental and other dimensions. However, a comprehensive, multidimensional, complex smart city is based on the urban planning paradigm of complexity and chaos which can lead to successful planning and management. The present study, from the perspective of modern chaos theory, is aimed to formulate strategic requirements for the realization of the smart city in Ahvaz metropolis.

This article is in the category of applied-developmental research, which is question-based. It has been accomplished using bibliographic and survey method, using exploratory factor analysis, one-sample t-test and Friedman ranking test in SPSS software. The survey instrument was a 5-point Likert questionnaire whose final content validity was confirmed by professors and its reliability was confirmed by Cronbach’s alpha coefficient of 0.906. The statistical population consist of the experts of the institutions involved in the smartening process of Ahvaz metropolis. A combination of clustered snowball sampling methods and monitored network was used in this research. Finally, 380 questionnaires were completed. The adequacy of the number of samples was confirmed by KMO method.

Based on the findings of the research, in relation to the theory of chaos, it is possible to conclude that Ahvaz metropolis is affected by the non-linear effect in the smartening process; also, the butterfly effect is significant in this metropolis. Moreover, in connection with the modulating variable of the power of universities and research institutes, sensibly, it can be accepted that the condition of this component is also not inappropriate. Using Friedman’s ranking test, the authors ranked the components and indicators including the butterfly effect of social and ethnic pluralism, social moderators, steady flow of energy, people, non-linear effect, variable modulating power of universities and research institutes, contexts, structural forces, institutional forces. Finally, the use of communication and information technology capabilities in promoting environmental quality (motivators) are located.

Based on the results of the research, nonlinear effects govern the process of smart city development in Ahvaz significantly. This implies that a nonlinear system, influenced by variables such as conflicting interests, developmental contradictions, ownership conflicts, and the level of technology acceptance by the public, dominates the realization of the smart city in Ahvaz. These factors have led to turbulent conditions in this metropolis. In this context, the impact of two key factors, namely, government and oil, on this process and system, as well as the central-peripheral dynamics shaped in the country, particularly in connection with the oil-rich city of Ahvaz, cannot be overlooked. As many researchers have emphasized in their studies, the government has commercialized money and capital in the cities through the vast banking system. It has helped the expansion of cities and urbanization more than ever. This extensive and unmatched influence of the government originates above all from the way of obtaining its revenue sources, i.e. the export of crude oil, the resulting national surplus has an important contribution to the accumulation of capital and expanding reproduction in the economic process of the country. In such an atmosphere, the military creation of the center and the periphery has caused the emergence of an unbalanced national development model. Therefore, as observed in the analytical research model, the government and oil entities, in addition to their impact within the framework of internal structural institutions of the Ahvaz metropolis, are considered external influential factors in the overall drivers of smart city realization in Ahvaz. The presence of these two entities, due to their interactions with each other and the factors of conflicting interests, developmental contradictions, ownership conflicts, and the level of technology acceptance by the public, intensifies the nonlinear effects in the process of smart city development in Ahvaz. Inside, the stimuli have stimulated the drives and the drivers - based on the theoretical foundations of smart cities - with the goal of achieving a more efficient, sustainable, livable and fairer city in an urban framework with dimensions of smart environment, smart life, smart economy, smart mobility, smart governance and smart people to mobilize resources and facilities. But in the meantime, the factor of social and ethnic pluralism as a factor with a butterfly effect can be effective in this movement from drivers to a smart city. Also, in this transformation, two social moderator variables and the power of universities and research institutes are effective in this movement. In addition, the internet access flows as a constant flow of energy on the entire system.

 From the perspective of modern sciences, fractal knowledge is a study of self-similar and self-organized structures that are the conceptual core of understanding nature’s geometry. From a mathematical viewpoint, nature follows fractal rules to create different forms. In this rationale, a direct interaction between architecture and fractals can be proposed.Research

This research, by posing questions about how fractal geometry is applied, explains the geometric laws of nature in the process of self-organizing in form-based architecture.Research

This applied research employs the method of correlation in applying geometries according to fractal properties conducting a qualitative, phenomenological view. In this study, seven stages are explained in fractal geometry as a form-based structure. These stages in form-finding, the hierarchy of connections, and geometric progressions provide a credible process in the application of fractal geometry to architecture. In addition, an architecture inspired by principles of nature’s geometry is based on three laws and functions in structure as described by the research: the law of self-similarity, the law of self-organization, and the law of unity. To validate these laws, three buildings are selected from the Gothic, Art Nouveau, and traditional Persian architecture periods, according to fractal properties. Fractal rules are analyzed in the evaluation of these structures using a comparative-descriptive model.

Based on the results, it can be concluded that fractal geometry has been incorporated into the structure, elements composition, and aesthetic concepts of ornamentation in the architecture of these edifices. Inspired by nature’s geometry, laws of proportions, rhythm, and self-similar forms, these architectural structures have created a wide range of fractal patterns, generating internal connections and external unification among the structural elements and architectural forms.
