一、概况结构构件设计时,应使所设计的构件在使用期内力求在经济合理下满足(1)强度、(2)适用、(3)耐久和(4)整体稳定。这里(1)、(4)项关系到人身安全,结构具有这种性质一般用结构的安全性来描述。(2)项属于结构的适用性而(3)项则属于结构的耐久性。结构安全性,适用性和耐久性三者的总称即结构的可靠性。可靠性的数量描述一般用可靠度;安全性的数量描述则用安全度。可靠度比安全度的含义更广泛,更能全面地反映结构的安全程
I. Overview When designing structural components, the designed components shall be designed to meet (1) strength, (2) application, (3) durability, and (4) overall stability under economical reasonable conditions during the use period. Here, items (1) and (4) are related to personal safety, and the structure has such properties that are generally described by the security of the structure. (2) belongs to the applicability of the structure and (3) belongs to the durability of the structure. Structural safety, applicability and durability are the general term for structural reliability. The quantitative description of reliability is generally used for reliability; the quantitative description of security is used for safety. Reliability is more extensive than safety, and it can more fully reflect the structural safety process.
