Based on the illustration of the using state of industrial buildings and the present appraisal method of structural reliability , the paper indicates the relationship between structural state and reliability , by analyzing the feature rule and reason of scathe and demolish of steel workshop , and puts forward the basic view of appraisal method of structural reliability . structural state is the external performance of structure ; the decline of structural performance and decrease of the reliability level are shown as the alter of structure state . therefore , the analysis and appraisal of structure state can evaluate the structural reliability indirectly 论文在阐述我国工业建筑使用状况和现有结构可靠性评定方法的基础上，通过分析钢结构厂房损伤、破坏的特点、规律和原因，指出结构状态与其可靠性之间的关系，并由此提出结构可靠性的状态评定方法的基本思想：结构状态是结构的外在表现，结构性能的衰退和可靠度水平的降低一般都可表现为结构状态的变化，因此通过对结构状态的分析和评价，可间接地对结构的可靠性作出评定。
The presentation of possibilistic reliability method have make it possible for reliability evaluation when only little information is available , or available information is limited or incomplete . ( e ) 5th , hybrid reliability theories of stochastic and non - probabilistic , stochastic and fuzzy , for structural systems were founded 能度可靠性方法的提出，西北工业大学博士学位论文郭书祥：非随机不确定结构的可靠性方法和优化设计研究为掌握数据信息较少、或信息不完整时结构的可靠性评估提供了依据。
Durability detection and evaluation of concrete structures origined in 1960 ' s of 20th century , china has made much research on it since 1990 ' s of 20th century . but , it nessary to build a system of durability detection and evalution of existing concrete structures now 混凝土结构耐久性检测与评估主要起源于二十世纪六十年代，我国于二十世纪九十年代初期起对此展开大量研究工作，但到目前为止，仅限于对混凝土结构的可靠性鉴定，缺乏一套完整的、适合工程实际特点的耐久性检测与评估体系。
For existing building , however , subgrade deformation usually exceeds the allowable subsoil deformation that is anticipated in design phase because of many reasons , which is especially serious in soft soil area . and this produces additional stress not considered in design stage and reduces the reliability of superstructure 对在役结构而言，地基往往会因为各种原因而出现超出设计预期的变形，尤对软土地区上建筑物的影响更为突出，导致上部结构产生设计未考虑到的附加效应，降低上部结构的可靠性。
For verifying the level of design about space structure and investigating the law of difference between practical internal force and internal force of design about member and nodal point , controlling the stress correctly and achieving optimum design . it is important that we investigate a new stress detecting technology which is easy used and has aptitude function for detect the internal force of long - span space structure . this topic take it as background 因此，为了检验大跨结构的设计水平，进行在役结构的可靠性评定，研究这类结构各杆件及节点的设计内力与实际值之间的变化规律，从而对其进行较为准确的控制并进行优化设计，寻找一种新的便于携带、使用可靠且具有一定智能功能的应力检测系统，用于测试大跨结构杆件及节点的实际内力就显得尤为重要，并且也具有很强的开发和应用前景。
So far , according to the design criterions of buildings , railways and ports , the design of the structures is based on the sections reliability of the components , the reason that it could not be designed based on the structural system reliabilities theory is the question of the failure dependences of the units or the sections of the components 目前，我国的建筑设计规范以及港口、铁路和水工规范等还都是以设计截面满足目标可靠指标来进行结构的可靠性设计的。致使不能进行结构体系可靠性设计的一个关键性问题即是结构体系中各失效单元或失效截面的失效相关性问题。
However , the structural modality is onefold , building of dwelling house remain with the extensive production in china , the productivity is low and wastage of the resource is generous ; so , it is necessary for housing structure sysyem to study and application new technology the technological development of housing industriy modernization is acomplex systematic project ; technological development in dwelling house structure is important for housing industriy modernization in china after the study of dwelling house structure class and characteristic , there set up a primary index system for evaluating the grade of dwelling house structure system 本文从住宅结构体系出发，研究了住宅结构体系的分类及各自特点，在此基础上建立了住宅结构体系评价指标体系，从住宅结构的可靠性、节能环保性、经济性、适用性、产业化程度等五个方面进行综合评价。应用本文建立起来的住宅结构评价指标体系对密肋壁板轻框结构体系进行了模糊综合评价，评价的方法为： ahp ? fuzzy法。
After analyzing the main modes of the duplicated fault tolerance system currently , the author gives readers new duplicated fault tolerance system based internet / intranet . the author also describes the architecture and their functions and the design and the implement of the software on the duplicated fault tolerance . the paper analyzes the reliability and safety of dual module hot spare architecture which is widely used to achieve high reliability and safety 作者在深入细致地分析、比较了当前常见的双机容错热备份系统的设计原理、设计思路、实现方法及其性能优缺点后，提出了一种新型的基于网络的双机容错热备份解决方案，阐述了该设计方案中的设计思路、设计原理、各部分的组成、功能以及设计方案实现过程，并且利用马尔可夫模型综合多种失效模式分析本文中双机容错热备结构的可靠性和安全性。
Structural health monitoring ( shm ) is an emerging applied technology in recent years , dealing with the development of techniques and system for the continuous monitoring , inspection and damage detection of structures , and its ultimate goal is to increase reliability , improve safety and reduce maintenance costs 结构健康监测是近年迅速发展的一项应用技术，涉及结构的连续监测、检查以及损伤探测。最终目的是增加结构的可靠性和安全性，降低结构维修的成本。
