| 摘 要： | 本文用试验研究了钢管超高强混凝土RPC(后称钢管RPC)短柱在轴压荷载作用下的性能,从分析RPC与普通混凝土和高强混凝土性能上的差异着手,探讨了钢管RPC在轴压作用下的受力变形机理与破坏特点。基于对试验结果和相关文献资料的综合分析,得到了计算钢管RPC承载力的经验公式,并与相关现行规程的计算结果进行了比较。结果表明,国内现行的一些钢管混凝土设计规程不适用于计算钢管RPC的承载力。

| Abstract: | Experimental investigation for characteristics of RPC-filled steel tubular columns with ultra high performance subjected to axial compressive loading are performed in this paper.Based on the analysis of the characteristic differences among the RPC,normal concrete and high strength concrete,the deformation mechanism and the failure modes of the RPC-filled steel tubular columns are discussed.Through processing and analysis of test results in the experimental investigation and literatures,the empirical formulas for estimating the load carrying capacity of the RPC-filled steel tubular columns are statistically worked out and compared with those in current design criteria.It is shown that the current design criteria for concrete-filled steel tubular columns are not suitable for the RPC-filled steel tubular columns. |
