结构可靠度理论的发展为钢管混凝土结构的可靠性分析提供了常用的概率分布和计算方法。根据钢管混凝土结构的承载力计算公式和四种影响误差,可以计算出其可靠度,与可靠指标比较,判断结构是否可靠。钢管混凝土结构可靠性分析的研究现状表明:由于试验数据有限、计算方法复杂、承载力计算公式不统一等问题,钢管混凝土结构的可靠性分析需要进一步的发展。
The development of structural reliability theory provides a common probability distribution and calculation method for the reliability analysis of CFST structures. According to the calculation formula and the four influence errors of the bearing capacity of the concrete-filled steel tubular structure, the reliability can be calculated and compared with the reliable index to judge whether the structure is reliable or not. The research status of CFST reliability analysis shows that the reliability analysis of CFST structure needs further development due to the limited test data, complicated calculation methods and the unification of bearing capacity formula.
