Sustainable seismic design (SSD) is a relatively new field of study that promises improved human welfare and innovative developments in structural engineering worldwide. In the present context, SSD refers to structural operability with a view to post-earthquake realignment and repair (PERR). The difference between conventional seismic design and SSD is the expected behaviour during and after earthquakes. In conventional earthquake-resistant systems, attention is focused on the response of the structure to code-level seismic demand whereas, in SSD, the post-earthquake attributes of the system are as important as those during the event. SSD is neither part of contemporary curricula nor codes of practice. This article promotes the notion that a structure can be seismically sustainable if it is able to prevent actual collapse, overcome residual effects and lend itself well to PERR. In order to gain insight into the inner workings of SSD, resort has been made to adaptive design, bioinspiration and the study of structural differences between conventional and seismically sustainable structures. It is shown that conventional seismic design can be upgraded to SSD without resorting to untenable costs and technologies.

开发可持续抗震结构的基础

可持续抗震设计 (SSD) 是一个相对较新的研究领域，有望改善全球结构工程的人类福利和创新发展。在目前的情况下，SSD 是指结构可操作性，以期地震后重新调整和修复 (PERR)。传统抗震设计与 SSD 之间的区别在于地震期间和之后的预期行为。在传统的抗震系统中，注意力集中在结构对代码级地震需求的响应上，而在 SSD 中，系统的震后属性与事件期间的属性一样重要。SSD 既不是当代课程的一部分，也不是实践规范的一部分。这篇文章提倡这样一种观念，即如果结构能够防止实际倒塌，它就可以在抗震方面具有可持续性，克服残余效应并很好地适用于 PERR。为了深入了解 SSD 的内部工作原理，采用了适应性设计、生物启发以及对传统结构和抗震可持续结构之间的结构差异的研究。结果表明，传统的抗震设计可以升级到SSD，而无需诉诸站不住脚的成本和技术。
