【摘要】 结构力学是直接为工程结构设计服务的,而工程设计中包含大量不确定性因素和信息,包括随机性、模糊性和未确知性信息．由于引用统计数学方法处理随机性问题,在结构力学中产生了可靠性理论和随机振动理论．随着模糊性和未确知性问题的提出和研究,近年来在结构力学中又逐渐形成了一些新的分支,包括结构的不确定性优化设计,广义(模糊随机)可靠性理论,模糊随机振动理论和模糊地震工程学等．本文简要地介绍这四个新的分支的发展情况,主要介绍作者及其学生们的工作,并着重介绍基本概念．更多还原

【Abstract】 Structural mechanics is directly used for engineering structural design, in which existsa vast amount of uncertain (including random, fuzzy and unascertained) information. With thetreatment of random information in engineering design, theory of structural reliability and theoryof random vibration were developed. Similarly, along with the treatment of fuzzy and unascer-tain information, some new branches of structural mechanics are developed. They are uncertainoptimum design of structures, generalized (fuzzy-random) theory of reliability, theory of fuzzy ran-dom vibration and fuzzy earthquake engineering. The fundamental ideas of those fields are brieflyintroduced in this paper.更多还原
