摘要

摘要: 对8个圆钢管橡胶混凝土轴心受压短柱进行试验研究，探讨橡胶粉取代率和橡胶粉粒径对圆钢管橡胶混凝土承载力的影响。采用有关设计规程包括：美国ACI(2005)和AISC(2005)、日本AIJ(2008)、英国BS5400(2005)、欧洲EC4(2004)及中国DL/T 50851999(1999)、DB21/T 17462009(2009)等对圆钢管橡胶混凝土的承载力进行计算。结果表明：随着橡胶粉取代率的增加和橡胶粉粒径的增大，圆钢管橡胶混凝土的承载力、刚度均有下降的趋势；上述各设计规程均能较好地计算圆钢管橡胶混凝土短柱的承载力，且计算结果偏于安全，其中，DL/T 50851999与圆钢管橡胶混凝土短柱试验结果最为吻合。

Abstract: Experiments on eight circular rubber concrete-filled steel tubular stub columns subjected to axial loadingare carried out． The influence of rubber replacing ratio and rubber particle size on the bearing capacity of the circularrubber concrete-filled steel tubular stub columns is analyzed． The bearing capacity of these specimens is calculated respectively by different codes，including ACI (2005，American)，AISC-LRFD (2005，American)，AIJ (2008，Japan)，BS5400 (2005，British)，EC4 (2004，Europe)，DL /T 50851999(1999，China)，DB21 /T 17462009(2009，China)，which are also compared respectively． The test results show that the bearing capacity and stiffness both decrease with the increase of rubber replacing ratio，and with the increase of rubber particle size． All results are somewhat conservative，the results of code DL /T 50851999(1999，China) are in agreement well with those of the tests． It is suitable to adopt the code DL /T 50851999(1999，China) to design circular rubber concrete-filled steel tubular columns．
