土建结构工程的安全性,即结构安全性是结构防止破坏倒塌的能力,是结构工程最重要的质量指标。结构工程的安全性主要取决于结构的设计与施工水准,亦结构的正确使用有关。从结构工程的设计方面,结构的安全性主要体现在结构构件承载能力的安全性、结构的整体牢固性与结构的耐久性等几个方面。 The safety of civil structure engineering, that is, structural safety is the ability of the structure to prevent collapse and collapse, and is the most important quality indicator of structural engineering. The safety of structural engineering mainly depends on the design and construction level of the structure, and also on the correct use of the structure. From the aspect of the design of structural engineering, the safety of the structure is mainly reflected in the safety of the bearing capacity of structural components, the overall solidity of the structure, and the durability of the structure.
