大跨空间结构理论研究和工程实践

Theoretical Study and Engineering Practice of Long-Span Spatial Structures

结构形式的创新和有力的理论研究支持 ,是大跨空间结构健康发展的两个关键因素。文章结合笔者参与的若干大型工程 ,从一个侧面反映我国十余年来在空间结构形式创新方面所进行的努力。简要介绍了笔者在悬索体系解析计算理论、单层网壳结构稳定性、网壳抗震性能和振动控制。

The development of long span spatial structures is characterized by the continual innovation of structural forms and the prompt support of theoretical studies. Several unconventional spatial structures designed by the author are introduced in this article as examples to demonstrate the efforts of Chinese engineers to create innovative structural forms in the recent two decades. Some theoretical studies by the author including the analytic theory of cable suspended structures, the stability of reticulated shells, the seismic behavior and vibration control of reticulated shells, as well as the wind induced response analysis of cable structures are also presented.
