摘要
结构可靠性理论的引入使工程结构的设计更合理、更科学,桁架结构布置灵活,目前已经广泛应用于工业与民用建筑中。本文主要介绍了桁架结构可靠性及其应用的国内外研究状况,对桁架结构可靠性理论的主要研究方向进行了总结。研究表明,桁架结构可靠性理论可以应用于结构的优化设计、加固、改造、监测和损伤识别等。最后结合桁架结构的受力特点,提出了桁架结构可靠性进一步研究的方向。
The introduction of structural reliability make the design of engineering structure more scientific and reasonable.The structural arrangement of truss is flexible,and the truss structure has been widely used in the industry and civil engineering currently.The study on the reliability of truss structure and its application domestic and aboard is mainly introduced,and the main study direction of the reliability of truss structure is summarized.The study indicated that the reliability theory of truss structure can be applied in optimization design,reinforcement,reconstruction,monitoring,damage identification,and so on.Finally,according to the mechanical characteristics of truss structure,the direction of further study is pointed out.
