钢筋混凝土构件中的梁式构件在结构体系中占有重要的地位,在实际工程中,梁式构件的结构性能会受众多因素的影响而减弱,严重时会造成巨大的人员伤亡和经济损失。结构可靠度设计中,基于正常使用极限状态下的可靠度研究,由于涉及到较多的随机变量,计算难度较大且模型较为复杂,所以对于这一方面的研究仍是值得深入探索的重要课题[1]。本文对钢筋混凝土构件可靠度研究中国内外现状以及发展趋势进行综述。
Beam members in reinforced concrete members occupy an important position in the structural system. In practical engineering, the structural performance of beam members will be weakened by many factors, causing serious casualties and economic losses in severe cases. In the design of structural reliability, based on the study of the reliability under the limit of normal use, as more random variables are involved, the calculation is more difficult and the model is more complicated, the research on this aspect is still an important topic worth exploring deeply [1]. In this paper, the status quo and development trend of the research on the reliability of reinforced concrete members in China and abroad are reviewed.
