Abstract

 Large-span spatial buildings are among the most technically challenging building types in modern engineering. Based on design requirements, this paper introduces technical issues related to structural form selection, parametric design, design loads, seismic and wind-resistant design, beam-column joint design, reinforcement detailing, structural optimization, and design scheme evaluation. It also proposes improvement measures from two aspects: structural parameter optimization and the application of new materials. The results show that the design of large-span spatial structures should pursue the goals of economy, safety, and aesthetics. On this basis, the use of advanced design concepts and technical methods is an effective approach to improving the design level of large-span spatial structures.
