Structural analysis often prioritizes load-bearing capacity and economic efficiency, neglecting qualitative criteria such as spatial and functional performance, which are critical to user experience and architectural design. This research introduces a novel quantitative assessment model employing fuzzy logic to bridge this gap, offering a systematic approach to evaluating spaceframe structures—renowned for their structural efficiency and aesthetic versatility. By addressing the inherent uncertainties in architectural evaluations, the model quantifies qualitative attributes like flexibility, geometric order, and safety, translating them into measurable metrics. Through theoretical exploration and case studies of diverse spaceframe structures, the study validates the model\\\\\\\\\\\\\\\'s precision, showing minimal deviations between expert evaluations and model scores. This innovative framework integrates user-centered and human-perception dimensions into structural assessments, making it a valuable tool for refining performance-based design practices in architectural engineering.
