摘要

复合材料柱的可靠性和性能受到许多因素的影响。本文对考虑力学和几何变异的方形组合柱在轴压作用下的可靠性和性能进行了比较研究。选择普通混凝土和高性能混凝土填充的金属空心型材。在这项研究中,提出了一个机械可靠性模型来计算可靠性指标和不同立柱的失效概率。响应面法用于实现这种耦合,以便在合适的模型中描述不确定性,并研究它们对可靠性评估的影响。结果表明,立柱的材料和几何特性对其强度和可靠性有显著影响。利用该方法对结构可靠度随机参数的敏感性进行了评估。

Reliability Analysis and Comparative Study of Ordinary Concrete and High Performance Concrete Filled with Steel Tube under Axial Compression
Reliability and behaviour of composite columns is influenced by many factors. This paper presents a comparative study of the reliability and performance of square composite columns under axial compression, taking into account mechanical and geometric variability. The choice is opted for metal hollow profiles filled with ordinary concrete and high-performance concrete. In this study, a mechanic-reliability model to calculate the reliability index and the probability of failure of different columns is presented. The response surface method is used to accomplish this coupling in order to describe the uncertainties in a suitable model and to study their influence for a reliability assessment. The results show that the material and geometric characteristics of the columns have a significant influence on strength and reliability. The sensitivity of the random parameters of structural reliability is assessed from the proposed method.

期刊介绍: "International Journal of Engineering Research in Africa" is a peer-reviewed journal which is devoted to the publication of original scientific articles on research and development of engineering systems carried out in Africa and worldwide. We publish stand-alone papers by individual authors. The articles should be related to theoretical research or be based on practical study. Articles which are not from Africa should have the potential of contributing to its progress and development.
