RuiXue Multi-Hall-Human machine collaboration in reciprocal structures

Abstract

This article centers on the RuiXue Multi-Hall architectural design project in Chengdu, China, with a specific focus on a comprehensive workflow framework that integrates reciprocal geometric design and digital construction methods, primarily within the context of shell structures. The research expands on the concepts of structural design, adjustments of performance parameters, and the optimization of free-form shells. In addition, it outlines the spatial design approach for the shell structure. The study delves into reciprocal geometric design for the existing shell structure, establishing a library of reciprocal geometric shapes suitable for architectural design. The primary focus is on the application of these shapes to the shell structure, optimizing parameters for several grids within the library, and comparing various design schemes. Furthermore, the article discusses digital construction methods for the existing shell space and reciprocal structure, with a specific emphasis on the material performance of timber components. This discussion includes reciprocal timber structures and 3D-printed roofs for shell surfaces, all guided by a geometric control system to facilitate an interactive design and construction process. This research on reciprocal geometric design and digital construction methods for shell structures holds dual significance. It not only traces the historical development of reciprocal structures but also explores innovative construction methods using digital technology. The establishment of a comprehensive framework for reciprocal geometric design-construction is expected to catalyze innovative breakthroughs in future architectural design, spanning aspects such as space, form, materials, and structure.
