一、前言系统可靠性分析是可靠性理论在结构分析和结构设计应用中的一个极为重要的内容。也是当前迫切需要解决的问题。“结构系统可靠性与结构单元可靠性”一文对此已作了较为详细的论述。该文介绍了结构系统可靠性分析的几种主要方法。并在综合这些方法的基础上,提出了结构系统可靠性分析的一般原则和步骤。本文是前文的继续,是在这些基础上,针对工程结构中一些最常见的基本结构,包括简支梁、桁架、刚架和连续梁进行了结构系统可靠 I. INTRODUCTION System reliability analysis is an extremely important part of reliability theory in structural analysis and structural design applications. It is also an urgent issue to be solved. The article “Structure System Reliability and Structural Unit Reliability” has been discussed in more detail. This paper introduces several main methods of structural system reliability analysis. On the basis of synthesizing these methods, the general principles and steps of structural system reliability analysis are put forward. This article is the continuation of the previous, is based on these, for some of the most common structure of the basic structure of the project, including simple beams, trusses, rigid beams and continuous beams of structural system reliability
