| 摘 要： | 大跨空间结构由于其体量大且多作为人流密集的公共场所,因而在各种非常规荷载作用下破坏将造成更大的经济损失、人员伤亡和社会影响。系统的从以下3个方面总结了近年来大跨空间结构抗震理论所取得的主要进展:(1)大跨空间结构精细化的抗震性能评估理论,主要包括材料本构模型、地震动多点输入和结构强非线性模拟;(2)大跨空间结构抗震性能提升与修复技术,主要包括结构减震技术和隔震技术的研究与应用;(3)大跨空间结构抗震设计理论与方法,主要包括基于性态的设计方法和功能可恢复性的抗震设计方法。通过以上部分的系统总结和论述,形成大跨空间结构统一的抗震设计指导思想,并对此类结构的抗震研究的发展趋势和方向进行展望,从而为大跨空间结构设计、施工和监测提供借鉴。

| Abstract: | The large span spatial structures, which characterized as large-scale buildings and public places with a large number of people flow, could cause greater economic losses, casualties and social impacts under various abnormal loads. In this paper, the main progress of seismic design theory of large span spatial structure in recent years is summarized from the following three aspects. (1) The theory of seismic performance evaluation for large span spatial structure mainly includes material constitutive model, ground motion multi-point input and simulation of structural strong nonlinearity; (2) The seismic performance improvement and repair technology of large span spatial structure mainly includes the research and application of structural vibration reduction technology and structural isolation technology; (3) The theory and method of seismic design for large span spatial structures, including performance-based seismic design and seismic design method with functional recovery. Through systematic summary and discussion, the unified seismic design guidelines for large span spatial structures, the development trend of seismic study on this structure and the direction of the future are discussed, which could lay a foundation for the design, construction and monitoring of large span space structures. |
