摘要:
采用配筋的超高性能混凝土(UHPC) 圆筒为模板,并内浇普通混凝土(NC)的UHPC-NC组合柱,具有强度高、耐腐蚀等优点。基于现有承载力计算方法并结合理论分析,提出UHPC-NC 组合柱轴压承载力简化计算方法。分别采用所提方法和他人的计算方法,计算所收集试件的轴压承载力,结果表明:所提方法的计算值与试验值的比值均值为1.023,方差为0.005,与有限元拓展参数值对比误差也均在10%以内,其计算精度较高。相关研究可为UHPC-NC组合柱在实际工程的推广应用提供参考。
Abstract:
The UHPC-NC composite column, which uses a reinforced ultra-high performance concrete (UHPC) cylinder as a formwork and is internally cast with normal concrete (NC), has advantages such as high strength and corrosion resistance. Based on the existing bearing capacity calculation methods and combined with theoretical analysis, a simplified calculation method for the axial compression bearing capacity of UHPC-NC composite columns is proposed. The axial compression bearing capacity of the collected specimens was calculated using the proposed method and other calculation methods. Results show that the mean value of the ratio of the calculated value to the test value by the proposed method is 1.023, with a variance of 0.005. The comparison error with the finite element extended parameter value is also within 10%. The calculation accuracy is relatively high. The relevant research can provide reference for the promotion and application of UHPC-NC composite columns in practical engineering.
