A key question is raised in the case of integrating and matching structure and architecture when creating structural architecture: is it possible to identify factors affecting this architecture and the status of these factors? For this purpose, this study explores the "theory of structural architecture" using grounded theory to reveal the causal, intervening, and context conditions, as well as the strategy and consequence of structural architecture. The results of this study show that the underlying approach for the design of structural architecture is to obtain causal conditions with some attributes, such as scientism and critical wisdom. Moreover, intervening conditions in this architecture includes tectonic background including executive power, economic issues, land and adjacencies, building use, ecology and vernacular identity and climate, culture, and coordination with time and building scale that have intervening effect on the context conditions or tectonic features within three functional, Formal, and semantic or meaning fields. These attributes include 18 features: smartness, safety, flexibility and resilience, strength and balance, optimality, paying attention to details, the definition of space, inspired by nature, paying attention to post-operational requirements, unity, combined with context, force cutting and optimal form, geometry, scale-based proportions, conveying a message, beauty, consistency, and stability. The structural architecture strategy derived from this study is divided into two parts of survey and action. In tectonic surveys and categories of analysis and decision, the designer must pay attention to vernacular architecture and ecology architecture, while it is essential in tectonic or tectonic action to use constructive pedagogy in structural architecture instruction based on various components, including exploratory model, critical and creative thinking. The consequence of structural architecture can be seen in different components, such as improved peace and comfort in the living environment.
